Discover the Oldest Cave Art: Hand-Painted Stencils Dating Back 68,000 Years

Recent findings reveal that these stencils are over 15,000 years older than cave paintings in another Sulawesi cave, which were dated in 2024. The painting features three anthropomorphic figures interacting with pigs, believed to be approximately 51,200 years old.

“I thought my previous work was impressive, but this photo completely eclipsed it,” Blum remarked.

“This underscores the long-standing tradition of rock art creation in this region. It spans an incredible timeline,” he emphasized.

Researchers are optimistic about uncovering even older art forms, including narrative art, in Indonesia, a largely unexplored archaeological treasure trove.

Liang Methanduno, a prominent cave art location, attracts tourists. However, most artworks discovered so far, depicting domestic animals like chickens, are relatively recent, estimated to be around 4,000 years old.

In 2015, Indonesian rock art expert and lead author, Adi Octaviana, spotted a faint drawing behind a modern painting, speculating it might be an ancient hand-painted stencil.

“These had never been documented before; their existence was unknown until Addy discovered them,” Blum stated.

Previous generations of researchers exploring Ice Age cave art, dating back 30,000 to 40,000 years in regions like France and Spain, believed it marked the dawn of modern artistic culture.

However, recent discoveries in Indonesia indicate that humans outside Europe were crafting “extraordinarily sophisticated” cave art tens of thousands of years ago, even before our species arrived in that area.

Blum noted that this discovery could also shed light on the timeline of when the first humans settled in Australia.

It is widely accepted that Aboriginal populations have inhabited Australia for at least 50,000 years, though evidence suggests one of the country’s archaeological sites is around 65,000 years old.

“The finding of 67,000 to 68,000-year-old rock art on Sulawesi, nearly adjacent to Australia, supports the theory that modern humans may have arrived in Australia at least 65,000 years ago,” Blum explained.

The parched landscapes of northeastern Saudi Arabia were once sufficiently moist to sustain a thriving fauna. Evidence suggests that ancient hominins also inhabited the area.

“This paper offers the initial comprehensive survey of the archaeological findings in the interior of northeastern Arabia, a vast region that has been largely overlooked,” states Monika Markowska from Northumbria University in the UK, who was not part of the study.

This research targets a largely uncharted segment of the Arabian Peninsula situated between Qatar and Kuwait. Despite the lack of recorded prehistoric human activity, scientists are aware that the region historically enjoyed enough rainfall to support a diverse ecosystem.

“Hominins have existed in Arabia for over 500,000 years and likely underwent several periods of habitation,” remarks Hugh Gourcutt from the University of Malta.

In their efforts to understand how ancient humans may have thrived in this environment, Gurkat and his team pinpointed ancient rivers and caves located near deposits of chert, a durable rock that prehistoric peoples used for tool-making. “Caves often serve as crucial archaeological sites, preserving fossils and climatic data,” Gurkat explains.

A total of 79 caves and their adjacent regions were investigated. Some contained signs of ancient life, both human and animal. One cave, in particular, was found next to an area where over 400 stone tools were scattered on the ground. Additionally, remains of ancient reptiles, bats, birds, camels, gazelles, hyenas, and wolves were uncovered within the cave.

By analyzing the characteristics of the stone tools, Groukat and his colleagues established that humans inhabited the vicinity of these caves between 10,000 and 100,000 years ago.

“Today, [Arabia] reveals an exceptional preservation of thousands of bones within these caves, providing invaluable insights into historical ecosystems,” notes Markowska.

Team member Michael Petraglia, who has dedicated years to researching Arabian archaeology at Griffith University in Australia, adds, “This research marks another milestone in understanding caves, rivers, their contents, and what they reveal about life in Arabia’s dynamic ecosystem.”

Cheetah Discovered Preserved as a Mummy in a Cave in Saudi Arabia

One of the mummified cheetahs found in a cave

Ahmed Boug et al. 2025/Saudi Arabia’s National Center for Wildlife

Recent findings report the discovery of seven cheetah mummies, dating back thousands of years, in caves located in Saudi Arabia.

The cheetah (acinonyx jubatus) populations have seen drastic reductions due to habitat destruction, hunting, and the wildlife trade, leading to their disappearance from the Arabian Peninsula several decades ago. Ahmed Boug and his associates at the National Wildlife Centre in Riyadh revealed details about these seven mummified cheetahs along with 54 skeletal sites found in the Lauga Cave Network in northern Saudi Arabia during the years 2022 and 2023.

The mummies, preserved through a unique process that inhibits decomposition, date back approximately 4,000 to 100 years.

“These discoveries are incredibly significant,” states Anne Schmidt Künzel from the Cheetah Conservation Fund in Namibia. “While the mummification of Negrids isn’t wholly unexpected, this marks a groundbreaking and important find.”

“The stable temperature and low humidity in the cave environment likely aided the mummification process,” the researchers noted.

The reason for the cheetahs’ presence in the cave remains a mystery, as these animals typically do not utilize caves as dens or for storing carcasses. At the time of investigation, none of the five caves revealed any water supply.

Many of the remains were located in caves accessible solely via sinkholes, leading Schmidt Künzel to propose that the cheetahs may have fallen and become trapped. Additionally, remains of other animals including insects, wolves, striped hyenas, gazelles, and red foxes were also discovered here.

Upon examining 20 complete cheetah skulls, researchers found that six belonged to adults, while the rest were from individuals aged between 6 and 24 months. There were also nine cub skeletons located in the primary cave. The abundance of young cheetahs indicates that adult females might have used the cave for collective protection, according to Schmidt Künzel.

Camera traps set up during the investigation indicated that wolves were also using these caves. “This implies that during the cheetah’s lifespan, they may have frequented several, if not all, of these caves, enabling them to enter intentionally,” Schmidt Künzel added.

While there is only one species of cheetah, it is divided into four genetically distinct subspecies. The Southeast African cheetah (acinonyx jubatus jubatus) is the most populous, while the Northeast African cheetah (acinonyx jubatus soemmeringii) and Northwest African cheetah (acinonyx jubatus heck) exist in smaller, fragmented groups. The Asian cheetah (acinonyx jubatus venaticus), meanwhile, has very few remaining members in Iran.

Boug and his team sequenced the genomes of three sets of artifacts. Their research indicated that the mummified individuals are most closely related to the Asian subspecies, currently found in that region.

Schmidt-Künzel emphasizes that this work supports the notion that all cheetah subspecies can adapt to similar arid conditions, making it feasible to reintroduce them to the area through selective breeding of African subspecies.

Study shows deliberate use of geometric patterns in Paleolithic artifacts from the Levantin Cave

In the new study, archaeologists analyzed five inscribed artifacts from the Paleolithic period in central Levantin. Two engraved levalovacores from the Manot and Kahuze caves, engraved plackets from the site of Kneitra, and flakes and cortical blades from the Amdo caves. Their findings highlight the intentionality behind the sculpture and provide important insights into the development of abstract thinking and the cultural complexity of mid-Paleolithic society.

Until now, the intentionality of central Paleolithic incised stone artifacts has been widely accepted and not fully supported by empirical testing.

Many archaeologists view these marks as functional and were created through the use of tools or natural wear.

Being skeptical of the existence of abstract or symbolic thinking in early hominins, understanding that symbolic actions such as art and abstract expressions appear much later than human evolution and are particularly relevant to modern people. I have.

Current research challenges the view by providing evidence of intentional and symbolic sculptures before global colonization by modern humans.

This study focuses on artifacts from major Levantin sites, including Dr. May Goldberger, an archaeologist at Hebrew and Ben Gurion University, as well as the outdoor sites of Manot Cave, Amdo Cave, Kahuze Cave and Queneitra. I guessed it.

Using advanced 3D surface analysis, the researchers examined the shape and pattern of the incision to distinguish intentional engraving from functional marks.

The findings reveal significant differences. The artifacts of Manot, Kahuze and Queneitra feature careful sculptures with geometric patterns that match the surface topography, highlighting aesthetic and symbolic intent.

In contrast, the incisions of artifacts from Amud Cave are shallow and unscattered, consistent with their functional use as an appraider.

“Abstract thinking is the basis of human cognitive evolution,” said Dr. Goder-Goldberger.

“The intentional sculpture found in these artifacts emphasizes the ability to represent symbolic representation and proposes a society with high conceptual capabilities.”

“The methodology we employed not only emphasize the intentional nature of these sculptures, but also provides for the first time a comparative framework for studying similar artifacts, enriching understanding of mid-term paleolithic society.” Zentrum für Archäogie, University of Johannes Gutenberg, University of Algarve.

“The inscribed artifacts of Qafzeh, Queneitra, and Manot are isolated initiatives within time series and geographical contexts, but the similarity of the shared properties and pattern structure of the incision itself suggests intentional and pre-determined behavior. I am.

“These findings provide a greater understanding of symbolic behavior and provide important insights into the cognitive and cultural development of early hominins.”

“This study illustrates an important step in understanding the scope of our ancestors' symbolic behavior and bridging the gap between the use of functional tools and abstract representation.”

Footprints of Pleistocene cave bears found in Spain

Paleontologists have discovered ancient bear footprints in Honseca Cave in northern Spain. Distinguishing cave bear and brown bear tracks is complicated, but cave bears are thought to be most likely to leave tracks at Honseka.

Cave bear footprints in Honseca Cave, Spain. Image credit: Rodriguez others., doi: 10.1080/10420940.2024.2446153.

Cave badger (Ursus Spelaeus) was a very large bear that formed the sister lineage of extant brown bears and polar bears.

These animals lived in Europe and Asia during the Pleistocene, but went extinct about 24,000 years ago.

It measured 2.7 to 3.5 meters (8.9 to 11.5 ft) in length, up to 1.7 meters (5.6 ft) at the shoulder, and weighed 225 to 500 kg.

People may have had occasional encounters with cave bears.

Despite their name, they did not actually live in caves, only using them for hibernation.

Nitrogen isotope data from giant crushed molars and their bones indicate that cave bears were primarily herbivorous, with leaves as their staple food.

“Cave bear footprints are not uncommon in the soft sediments of caves on the Iberian Peninsula, and many speleologists are well aware of their presence,” said Dr. Ana Mateos of the Center for Human Evolution and Human Research (CENIEH). .

“However, until now these fossil traces have not been the subject of systematic study.”

“In fact, only one study of this kind has ever been carried out in Romania's Ursilor Cave.”

Mateos and his colleagues discovered 16 cave bear footprints in Honseca Cave in Palencia, Spain.

The footprints were assigned to Ursichnus europaeus This is the first record of this species discovered in a cave on the Iberian Peninsula.

“We performed a scan of the footprint surface and its surroundings using a laser scanner that creates a three-dimensional cloud of millions of points, and combined this with a photogrammetric model.” said Dr. Adrian Martinez. CENIEH technician.

“This model has been used to take various measurements of footprints and compare them with those of other caves in Europe, such as the Ursilol Cave in Romania.”

“Furthermore, by processing the model, we were able to generate images that highlight the shape of individual footprints,” added Dr. Alfonso Benito, also from CENIEH.

“The shape of the toe impressions and the length of Urushiro's and Honseka's claw marks suggest that in both cases they belong to the cave bear, which went extinct about 28,000 years ago, rather than to brown bears.”

“Unfortunately, before scientists knew about their existence, some of the footprints were destroyed by the footprints of amateurs who had not paid attention and visited the interior of the cave,” said Jesús of CENIEH. Dr. Rodriguez said.

“Therefore, one of the goals of this type of research is to highlight the value of these fossils and promote their preservation.”

Archaeologists claim Eswatini’s Lion Cave is the oldest ocher mine in the world

Archaeologists say they have discovered the world’s oldest known evidence of intensive loess mining at least 48,000 years ago at Lion Cave in Ngwenya, in the landlocked southern African nation of Eswatini. .



Selected hand specimens of samples from sources included in the study: Ngwenya High Grade (AC), Ngwenya Low Grade (DF), Kubuta (G), Bulembu (HJ), Ruhorodum (K,L), Munyongane (M , N), Maroma (O). Scale bar – 1 cm. Image credit: McDonald’s others., doi: 10.1038/s41467-024-53050-6.

Ocher is widely recognized as a red, yellow, or purple pigmented earth mineral, often confused with manganese oxide (black ocher), and its importance throughout human history has been debatable. there is no.

Records remain from ancient times, where it was extracted through intensive mining operations, transported over long distances, used in symbols and funerary expressions, and processed to enhance its properties and performance in complex paint mixtures. Masu.

It continues to hold widespread cultural significance in many descendant communities today.

However, the differences between ocher colors are not always obvious, and pigments that appear the same in color and texture often have different physicochemical properties.

“Ocher can be said to be the earliest pigment used by humans to depict the world,” said archaeologist Dr. Gregor Bader of the Senckenberg Center for Human Evolution and Paleoenvironment at the University of Tübingen.

“We humans and other humans have been using red, yellow, and sometimes purple earth minerals for at least 500,000 years, and probably much longer.”

In the most comprehensive study to date of ocher use in Africa, Dr Bader and his colleagues investigated how this mineral was used south of the Sahara.

Based on 173 samples from 15 Stone Age sites, the researchers reconstructed the regional network of mineral selection, extraction, transport and use of ocher.

“We were interested in the entire processing chain of loess: from the selection of minerals from different geological formations, their extraction, and the mixing of other substances such as milk, fat, blood, and vegetable resins as binders to the loess. It’s an archaeological site,” Dr. Bader said.

“How was the knowledge of ocher extraction transmitted? Was there interaction between different hunter-gatherer groups? And are there regional or temporal differences?

This study shows that there was both a regional strategy for sourcing ocher and long-distance transport of important minerals through a network of different mineral deposits.

Archaeological investigations at 15 sites suggest the existence of long-term cultural continuity in the intergenerational transmission of knowledge regarding ocher extraction and use, including geological conditions and desirable physicochemical properties of mineral pigments. I’m doing it.

These communities of practice did not develop in isolation but were part of a broader system of relations influenced and mediated by social interactions such as technical learning, seasonal migration, exchange of material culture, and symbolic expression. It was a club.

“Our data support the hypothesis that hunter-gatherers in Stone Age Eswatini were highly mobile, sometimes traveling long distances to transport ocher pigments,” Bader said. said.

“It is noteworthy that such traditions continue to this day in Eswatini. For example, it is ethnographic that plant healers travel to collect mineral earth pigments for painting and healing ceremonies. known from research.

“Ocher is also considered an important part of the wedding ceremony. On the morning of the wedding, the bride is painted in red ocher and animal fat to signify her new status within the community.”

“Our current research shows that Eswatini researchers are in a leading position in the study of Stone Age loess resources, and provides an impressive demonstration that this country holds vast wealth of this important pigment. It shows.”

“In addition to elucidating the chain of loess exchange, we also used optically stimulated luminescence dating to show that Ngwenya’s Lion Cave is the oldest concentrated loess site in the world, dating back approximately 48,000 years. We have confirmed that this is known evidence of mining.”

“Furthermore, here we see some of the earliest evidence that humans were actively reshaping the environment.”

Tajikistan Unearthed: A Paleolithic Rock Cave Called Soy Havzak

The Soy Habzak trenches in Tajikistan's Zeravshan Valley are the remains of several Paleolithic occupation phases rich in stone tools, fauna, and charcoal remains.



The Soi Habzak Caves are one of the few multi-layered Paleolithic ruins in Central Asia. Image credit: Yossi Zaidner & Sharof Kurbanov, doi: 10.15184/aqy.2024.149.

Soy Habzak is a small tributary of the Zeravshan River approximately 10 km north of Panjikent in northern Tajikistan.

The Soi Havzak ruins are rock shelters/overhangs carved into the cliff face approximately 40 meters above the river.

Professor Yossi Zeidner of the Hebrew University, Dr. Sharov Kurbanov of the National Academy of Sciences of Tajikistan and colleagues excavated three areas of the site, revealing layers of human activity.

Archaeologists have discovered a wealth of Paleolithic stone tools, animal bones, and plants.

The finds date back to various periods between 150,000 and 20,000 years ago.

These provide important evidence that Central Asia played an important role in early human migration and development.

“It turns out that the Zeravshan Valley, which in the Middle Ages was primarily known as the route of the Silk Road, was an important route for human expansion long before that, from 20,000 to 150,000 years ago,” said Zeidner. the professor said.

“This region may have served as a migratory route for several human species that may have coexisted in this region, including modern Homo sapiens, Neanderthals, and Denisovans, and our The aim of the study is to determine who the humans were who lived in this region and the nature of their interactions.

The well-preserved finds at Soi Habzak not only provide valuable clues about the ancient climate and environment, but also the possibility of discovering hominin artifacts that could identify the species of humans that lived in the area. also brings.

“The state of preservation of not only the bones but also the organic matter, such as the remains of burnt wood, is amazing,” said Professor Zeidner.

“This allows us to reconstruct the region's ancient climate and provides hope that further excavations may reveal clues about the region's human biology.”

“This is critical to understanding the development of human population and behavior in Central Asia.”

This research has broader implications for the study of human evolution and migration, particularly for understanding how ancient human populations interacted.

The Soi Habzak site in the mountain corridor of Central Asia may have served as an important transition point for human populations, allowing early humans to spread across vast areas.

“We hope that ongoing research at this site will provide new insights into how different human groups, including modern humans, Neanderthals, and Denisovans, interacted in this region. '' said Professor Zeidner.

“This discovery is an important step towards understanding the history of ancient humans in Central Asia and demonstrates important collaboration between international scientific teams.”

Possible Discovery of Lunar Cave Entrance Deep Hole on the Moon

Proposed underground geometry of the Mare Tranquillitatis on the Moon

Wagner and Robinson

A network of caves may be hidden just beneath the Moon's surface, and researchers may have finally discovered an access point. These caves have long been predicted, but until now it has been difficult to prove their existence or find a way to directly explore them with future missions.

The Moon's surface is dotted with holes, or so-called skylights, which are openings in the ceilings of caves that are thought to have been formed by the collapse of ancient lava tubes – tunnels formed when lava flows beneath the solid crust. Leonardo Carrell Researchers from the University of Trento in Italy have discovered that the deepest part of these formations, the “The Pit of the Sea of ​​TranquilityThese images were taken by NASA's Lunar Rover in 2010.

By comparing their simulations with lava tubes on Earth, the researchers found that the Mare Tranquillitatis hole appears to open into a large cavern buried at least 400 feet (130 meters) underground. The cave appears to be about 150 feet (45 meters) wide and at least 100 feet (30 meters) long, but could be much larger.

Caves like these could offer a unique window into the evolution of the Moon, says Carell. “Analyzing rocks from lunar caves, which have not been altered by the harsh lunar environment, could provide important insights into key scientific questions, such as the timeline and duration of volcanic activity on the Moon and the actual composition of the Moon's mantle,” Carell says.

The same stone ceiling that protects the cave rocks from the intense radiation experienced on the surface could also provide valuable shielding for future human explorers on the Moon. “Unlike the surface of the Moon, where temperatures change dramatically between day and night, [the caves] “It has a stable internal temperature, and it's also a natural shield against radiation and impacts,” Carrell says.

The idea of ​​using natural caves like these as lunar base camps has long been popular, and future astronauts may one day call the Sea of ​​Tranquility home.

Oldest Evidence of Storytelling in Art Found in 51,200-Year-Old Indonesian Cave Paintings

Archaeologists used a new technique called Laser Ablation U-series (LA-U-series) to re-date some of the oldest cave paintings in the Maros-Pangkep region of South Sulawesi and date stylistically similar motifs at other Maros-Pangkep sites. They found a minimum age of 50,200 years ago (± 2,200 years) for a hunting scene from the Leambur Sipong 4 cave site, first dated to a minimum of 43,900 years ago using a previous approach, meaning it is at least 4,040 years older than previously thought. They also assigned a minimum age of 53,500 years ago (± 2,300 years) to the newly described Leang Karampuang cave painting. Painted at least 51,200 years ago, the narrative work depicts human-like figures interacting with pigs and is now known as the world's oldest surviving example of figurative art and visual storytelling.

Prehistoric rock art provides important insights into past human cultures, but is typically difficult to date in an accurate and reliable way.

Over the past few decades, solution-based U-series methods have been used to determine early dates for rock art in several regions, including Western Europe, island Southeast Asia, and Siberia.

In Spain, a handprint stencil was dated to at least 64,800 years ago by solution U-series analysis of the overlying calcite and attributed to Neanderthals.

Until now, the oldest evidence of representational art is a naturalistic painting of a warthog at Reang Tedonggae in Maros-Pangkep, Sulawesi, which was dated to at least 45,500 years ago using the solution U series.

“We have previously used uranium-series methods to date very ancient rock art in two areas of Indonesia, Sulawesi and Borneo, but our new laser ablation U-series (LA-U-series) technique is more accurate,” said Professor Maxim Aubert from Griffith University, lead author of the study.

“This will allow us to date the oldest calcium carbonate layers that formed in the murals and get a more accurate idea of when the murals were created. This will revolutionize the dating of murals.”

“The innovative technique we developed allows us to create a detailed 'map' of the calcium carbonate layers,” added study co-author Professor Renaud-Joannes Boyau from Southern Cross University.

“This feature makes it possible to precisely identify and avoid areas affected by natural diagenesis resulting from complex growth histories.”

“As a result, dating of rock art becomes more certain and reliable.”

The discovery that the Leang Karampuang paintings are at least 51,200 years old has important implications for understanding the origins of early art.

“Our results are very surprising. Apart from some controversial finds in Spain, none of the famous Ice Age rock arts in Europe are this old. This is the first time that Indonesian rock art has been dated to more than 50,000 years,” said the study's lead author Adi Agus Octaviana, a rock art expert at Jakarta's National Research and Innovation Agency and a doctoral student at Griffith University.

The scientists also used the LA-U series technique to re-date calcium carbonate deposits that lie above cave paintings at the Leang Bru Sipon 4 cave site.

The paintings, which consist of narrative “scenes” depicting figures interpreted as therianthropes (half-human, half-animal) hunting warthogs and dwarf buffalo, were estimated by the team to be at least 43,900 years old.

Using new techniques, the authors prove that the artwork dates to a minimum of about 48,000 years ago, making it 4,040 years older than present.

“The cave paintings at Leang Karampuang and Leang Bul Siphon 4 shed new light on a great period and the vital role of storytelling in art history,” said Professor Adam Blum of Griffith University, co-author of the study.

“It is remarkable that the oldest cave paintings found so far in Sulawesi consist of recognizable scenes – pictures of humans interacting with animals – and we can infer that the artists were trying to tell some kind of story.”

“This was a new discovery because the academic consensus on early figurative cave art was that it consisted of panels with single figures, no clearly defined scenes, and that pictorial representations that conveyed a narrative emerged much later in European art.”

This discovery suggests that narrative storytelling has been an important part of human artistic culture in Indonesia from very early times.

“Humans have probably been telling stories for much longer than 51,200 years, but because words don't fossilize we have to rely on indirect evidence like depicted scenes in artwork, and the Sulawesi artworks are the oldest such evidence known to archaeology so far,” Octaviana said.

Exploring a Hidden Mexican Cave and Diving with Manatees

A mother manatee (pictured above) swims up to a cave diver in a flooded cave in Quintana Roo, Mexico's Yucatan Peninsula. Klaus ThiemannThey captured amazing photos of these endangered mammals living in unique, unexplored habitats. “Of course I think she's looking at me,” Tyman says. “But in reality, she's probably seeing what's on camera.”

Carved into the limestone by flowing water, this cave system is thought to be up to 16,000 kilometers long and connects coastal and inland cenotes, freshwater-filled sinkholes created when cave roofs collapse. is. Timan and his fellow divers have been exploring this system (pictured above) to photograph manatees, which, unlike humans, can easily navigate passages.

Although manatees have likely lived in the area for generations, it is estimated that fewer than 250 manatees exist in the Mexican Caribbean, Tiemann said. Timan is concerned that nearby construction projects are endangering aquatic species in the area. A new railway line will further develop this popular tourist destination (pictured above). Construction can impede the flow of water through the system, starving it of oxygen and trapping manatees. Wastewater from surface runoff and sewage systems degrades the water quality of local aquifers.

Although the coastal area is protected as a manatee sanctuary, it does not extend as far inland as the manatees were photographed. So while the discovery of manatees in a relatively pristine cave system is good news, these habitats may not remain pristine for very long.

This reptile specimen and associated skeleton were collected by long-time paleontology enthusiasts Bill and Julie May. Richards Spara limestone cave system in Oklahoma that is currently undergoing quarrying.

The skin fragments are smaller than fingernails and have a pebble-like surface, most similar to crocodile skin.

This is the earliest preserved example of the epidermis, the outermost layer of skin, in terrestrial reptiles, birds, and mammals, and was an important evolutionary adaptation in the transition to terrestrial life.

“Every once in a while, we have a unique opportunity to glimpse deep into time,” said Ethan Mooney, a graduate student at the University of Toronto.

“Discoveries of this kind can really enrich our understanding and appreciation of these pioneering animals.”

Skin and other soft tissue rarely fossilize, but Mooney and colleagues say that this is possible thanks to unique features of the Richards Spur Cave system, including fine clay deposits that slow decomposition, oil seepage, and a cave environment. We believe that in this case it was possible to save the skin. It was probably an environment without oxygen.”

“Animals would have fallen into this cave system during the early Permian period and become buried in very fine clay sediments, slowing down the process of decay,” Mooney said.

“What is surprising, however, is that this cave system was also the site of an active oil seepage during the Permian, and the interaction of the hydrocarbons in the oil with the tar is likely what enabled the preservation of this surface. is.”

Analysis of the specimens revealed epidermal tissue, a characteristic of the skin of amniotes, a group of terrestrial vertebrates that includes reptiles, birds and mammals that evolved from amphibian ancestors during the Carboniferous Period.

“What we saw was completely different from what we expected, so we were in complete shock,” Mooney said.

“Finding ancient skin fossils like this is a unique opportunity to peer into the past and learn what the skin of these early animals looked like.”

The skin shares features with ancient and extant reptiles, including a pebble surface similar to crocodile skin and hinge areas between epidermal scales similar to the skin structure of snakes and earthworm lizards.

However, because the skin fossils are not associated with skeletons or other artifacts, it is not possible to determine which species or body part the skin belonged to.

The fact that this ancient skin resembles the skin of reptiles living today shows how important these structures are for survival in terrestrial environments.

“The epidermis was an important feature for vertebrates to survive on land. It is an important barrier between internal processes and the harsh external environment,” Mooney said.

“This skin may represent the skin structure of an early amniote terrestrial vertebrate ancestor that allowed for the eventual evolution of feathers in birds and hair follicles in mammals.”
