Archeopteryx’s Feeding Structures: Evidence of Evolving Flight Demands, Researchers Reveal

A groundbreaking study by paleontologists at the Field Museum of Natural History reveals that Archeopteryx, the oldest known bird, has a feeding mechanism intricately shaped by the demands of early flight. This discovery implies a simultaneous evolution of diet and aerodynamics during the early history of birds. For detailed insights, check the full report, coming this week in Innovation.

Flying demands a significant amount of energy compared to walking, swimming, or running, making it one of the most physically taxing forms of exercise. Birds have therefore evolved specialized strategies for efficient food intake and digestion.

Archeopteryx, the oldest known bird-like dinosaur, inhabited regions of present-day Germany around 150 million years ago during the Jurassic period.

Dr. Jingmai O’Connor, associate curator of fossil reptiles at the Field Museum, states, “For a long time, the characteristics defining the transition from land-based dinosaurs to avian dinosaurs were poorly understood.”

Dr. O’Connor notes, “The unique features found in Archeopteryx that are also present in modern birds provide new criteria for determining avian characteristics in dinosaur fossils.”

This research focused on the latest Archeopteryx specimen from Chicago, enhancing our scientific understanding of this ancient bird.

The team compared the preserved tissues of Archeopteryx to the oral papillae of contemporary birds, leading to the significant finding that they identified the first example of an oral papilla in Archeopteryx, as well as the first in the fossil record.

Additionally, the study uncovered several previously unseen features within the skull of Archeopteryx.

A small bone fragment, identified as a tongue bone, was discovered. While human tongues lack bones, many birds possess a series of bones that structure their tongues, allowing for greater flexibility and food manipulation.

“This tiny bone is one of the smallest in the body, yet it indicates that Archeopteryx had a highly mobile tongue, similar to many modern birds,” said Dr. O’Connor.

CT scans also revealed small tunnels at the tip of Archeopteryx’s beak, indicating the presence of nerve traces. Many birds possess a beak tip organ, a sensitive feature at the end of the beak that aids in food foraging.

These findings collectively suggest that Archeopteryx utilized oral papillae, lingual bones, and beak tip organs to develop advanced feeding mechanisms, reflecting their adaptive strategies for survival in flight.

“Our results indicate a significant transformation in feeding strategies as dinosaurs took to the air to meet the high-energy demands of flight,” Dr. O’Connor added.

“Birds possess incredibly efficient digestive systems, designed to maximize the energy extracted from food—a process that begins right in the mouth.”

Jurassic Dinosaur Fossils Illuminate the Evolution of Flight

Paleontologists studied fossils that are 160 million years old. Anchiornis Huxley, a non-avian theropod dinosaur, was unearthed from the Late Jurassic Tianjishan Formation in northeastern China. The preserved feathers indicated that these dinosaurs had lost their flying capability. This rare find offers insights into the functions of organisms that existed 160 million years ago and their role in the evolution of flight among dinosaurs and birds.

This fossil of Anchiornis Huxley has nearly complete feathers and coloration preserved, allowing for detailed identification of feather morphology. Image credit: Kiat et al., doi: 10.1038/s42003-025-09019-2.

“This discovery has significant implications, suggesting that the evolution of flight in dinosaurs and birds was more intricate than previously understood,” said paleontologist Yosef Kiat from Tel Aviv University and his team.

“It is possible that some species had rudimentary flight abilities but lost them as they evolved.”

“The lineage of dinosaurs diverged from other reptiles approximately 240 million years ago.”

“Shortly after (on an evolutionary timeline), many dinosaurs began developing feathers, unique structures that are lightweight and strong, made of protein, and primarily used for flight and thermoregulation.”

About 175 million years ago, feathered dinosaurs, known as Penaraputra, emerged as distant ancestors of modern birds; they are the only dinosaur lineage that survived the mass extinction marking the end of the Mesozoic Era 66 million years ago.

As far as we know, the Pennaraputra group developed feathers for flight, but some may have lost that capability due to changing environmental conditions, similar to modern ostriches and penguins.

In this study, the researchers examined nine specimens of a feathered pennaraptorian dinosaur species called Anchiornis Huxley.

This rare paleontological find, along with hundreds of similar fossils, had its feathers remarkably preserved due to the unique conditions present during their fossilization.

Specifically, the nine fossils analyzed were selected because they retained the color of their wing feathers: white with black spots on the tips.

“Feathers take about two to three weeks to grow,” explains Dr. Kiat.

“Once they reach their final size, they detach from the blood vessels that nourished them during growth and become dead material.”

“Over time, birds shed and replace their feathers in a process known as molting, which is crucial for flight.” He notes that birds that depend on flight molt in an organized and gradual manner, maintaining symmetry and allowing them to continue flying during the process.

Conversely, the molting of flightless birds tends to be more random and irregular.

“Molting patterns can indicate whether a winged creature was capable of flight.”

By examining the color of the feathers preserved in dinosaur fossils from China, researchers could reconstruct the wing structure, which featured series of black spots along the edges.

Additionally, newly grown feathers, which had not fully matured, were identifiable by their deviation in black spot patterns.

A detailed analysis of the new feathers in nine fossils revealed an irregular molting process.

“Based on our understanding of contemporary birds, we identified a molting pattern suggesting these dinosaurs were likely flightless,” said Dr. Kiat.

“This is a rare and particularly intriguing discovery. The preservation of feather color offers a unique opportunity to explore the functional characteristics of ancient organisms alongside body structures found in fossilized skeletons and bones.”

“While feather molting might seem like a minor detail, it could significantly alter our understanding of the origins of flight when examined in fossils,” he added.

Anchiornis Huxley‘s inclusion in the group of feathered dinosaurs that couldn’t fly underscores the complexity and diversity of wing evolution.”

The findings were published in the journal Communication Biology.

Baby Palace Took Flight Immediately After Hatching, But Crashed in the Storm

Artist’s impressions of a pterodactyl hatchling battling a tropical storm

The young pterodactyl appeared to have taken flight just days post-hatching, yet some individuals suffered broken wings during a turbulent storm that struck their lagoon habitat.

This immature pterodactyl possessed an adult-like wing configuration, showcasing strength and aerodynamic traits conducive to flight. However, paleontologists have long questioned whether newly hatched individuals were capable of flying.

At the Solnhofen site in southern Germany, countless plant fossils are trapped in limestone. During an examination using ultraviolet light at Haassov’s Museum Bergel, David Unwin and Robert Smith from the University of Leicester, UK, identified a fractured wing of a Pterodactylus antiquus specimen. They soon discovered another hatchling exhibiting the same wing fracture.

“We were astounded,” stated Unwin. “We are not easily shocked. Under UV light, it practically leapt out of the rock. Our immediate reaction was, ‘Bloody hell!’

Unwin and his team estimated that these two specimens, both measuring just 20 cm and still in their growth phase, lived around 150 million years ago, approximately two million years apart. At that time, the location was part of an archipelago, featuring numerous islands and saltwater lagoons, where intense tropical cyclones occasionally triggered rapid underwater landslides that helped preserve fossilized remains.

The hatchling’s bones exhibited a healthy structure without signs of rotation or healing, apart from clean, angled breaks in the humerus (the upper arm bones supporting the wings). These injuries resemble the typical wing damage that adult birds and bats sustain when navigating through oceanic storms.

“The most plausible explanation for these unfortunate pterosaurs with fractured wings is that they were airborne during the incident,” Unwin notes.

“In calm conditions, they could potentially float, but turbulent, wave-driven surfaces would cause them to sink.”

These findings bring valuable evidence to the long-standing debate regarding flight capabilities in hatchling pterosaurs, according to researchers.

“I don’t believe they hatched and simply leapt into the air,” Unwin stated. “However, they were likely airborne almost immediately post-hatching. This is one reason why these very young specimens are represented in the fossil record today.”

SpaceX’s Starship Rocket Successfully Concludes Test Flight

SpaceX Starship Rocket launches in its 10th flight test from Starbase, Texas, Launch Complex 1

UPI/Alamy

The SpaceX Starship, recognized as the most powerful rocket globally, has successfully completed a suborbital test flight following three previous launches that ended in catastrophic explosions.

SpaceX aims to develop a highly reusable and formidable launch vehicle. After several years, the Starship program is set to take over the deployment of Starlink satellites and play a pivotal role in NASA’s Artemis Moon Missions. Elon Musk, the owner of SpaceX, has stated that Starship is crucial for his ambition to colonize Mars.

The company embraces a fail-fast approach, more typical of Silicon Valley than the traditional methods prevalent in the aerospace industry. Despite aiming for rapid iterations, recent failures have raised concerns among observers.

Previous test flights (7, 8, and 9) ended in disaster with the upper stage either exploding or failing to land safely. The preparations for the 10th flight faced challenges when the upper stage detonated while holding propellant during ground tests.

This failure drew criticisms and led to doubts about SpaceX’s ability to achieve rapid reusability. Nevertheless, the test flight on August 10 from Starbase, Texas, was mainly successful, despite two previous cancellations.

The upper stage reached orbit and successfully deployed eight mock Starlink satellites to evaluate engine performance in a vacuum. Although an unexpected explosion damaged the engine area, the spacecraft completed its objectives, re-entering Earth’s atmosphere and achieving a controlled splashdown in the Indian Ocean. The positioned camera-equipped buoy provided engineers critical insights into the craft’s operations.

The booster stage detached and performed a controlled splashdown in the Gulf of Mexico.

While SpaceX did not provide specific comments, they stated on their website that all “primary objectives were met” during the mission.

Patrick Harkness, from the University of Glasgow, remarked that the launch was “an incredible achievement that allowed them to approach high volumes of space at low-cost altitudes.”

Despite advancements, questions linger regarding whether the spacecraft will be ready in time for NASA’s Artemis III lunar landing, planned for 2027. SpaceX remains committed to sending the spacecraft to Mars in 2026, amid ongoing challenges.

Two Unwelcome Viruses Could Be Disrupting Honeybee Flight

Honeybees battle infectious fungi, bacteria, mites, and viruses daily.

Anthony Brown/Alamy

Two non-threatening viral infections in adult honeybees are surprisingly covert and might disrupt their flying ability. One virus enhances speed, while the other acts as a brake.

Bees face a continual fight against infectious fungi, bacteria, mites, and viruses, many of which pose a threat to entire colonies. However, not all pathogens are equally harmful. For instance, both the deformed wing virus (DWV) and the sacbrood virus (SBV) can lead to severe symptoms if they infect honeybees during their early development. Despite being linked to increased mortality and a decrease in colony size, infection in adult honeybees is often viewed as asymptomatic. Michelle Flenniken from Montana State University and her team questioned whether these viruses were truly harmless.

The researchers studied bee health through their flight capabilities and infected bees with either DWV or SBV. After three days, the bees were tethered to a device resembling a set of small balls, forcing them to fly in circles. A total of 240 bees were observed, and the team measured their flight speed, duration, and distance.

Flenniken and her colleagues found that bees infected with DWV flew at slower speeds compared to uninfected counterparts. Conversely, those infected with SBV exhibited enhanced flight performance. The team predicts that bees with high DWV levels will cover 49% shorter distances than healthy honeybees. In contrast, severely infected SBV bees could experience a flight range increase of up to 53%. “SBV infections are detrimental to larvae and typically harm overall colony health,” says Flenniken.

This research reshapes our understanding of the subtle and odd impacts stealth infections can have on honeybee behavior. Other pathogens are known to influence bee actions. For instance, the Kako virus, a distinct variant of DWV, may provoke more aggressive behavior in bees, as noted by Eugene Riabov, who was not part of this research at the James Hutton Institute in the UK.

“It’s fascinating to observe how members of both DWV and SBV, which are closely related, exhibit such contrasting effects on honeybee aerodynamics,” remarks Riabov.

By disrupting bees’ ability to fly and collect nectar, viruses like DWV could negatively affect their pollination of nearby plants, complicating their foraging efforts. Consequently, as bees struggle, the implications reverberate throughout the entire ecosystem.

SpaceX Gears Up for Its Ninth Starship Test Flight

SpaceX is set to launch the Starship Megarocket on a crucial test flight this Tuesday, following two earlier unsuccessful attempts. Both previous launches ended in failure when the upper-stage vessels exploded in the Gulf of Mexico and parts of the Caribbean, resulting in substantial debris.

The upcoming Non-White Crime Launch, marking Starship’s 9th Test Flight, is scheduled for liftoff from the Starbase facility in Texas, with a launch window opening at 7:30 PM.

Standing at 400 feet, this spacecraft represents the most powerful rocket ever created and comprises two main components: a first-stage booster known as Super Heavy and the upper-stage spaceship. The Megarocket is central to CEO Elon Musk’s ambitions for Mars exploration.

Following Tuesday’s test flight, Musk is anticipated to deliver a presentation from Texas titled “The Road to the Road Beyond the Lifespan.”

Musk has recently shifted his focus back to SpaceX and Tesla, having stepped back from his prominent presence in the Trump administration. Since the start of the current presidential term, he has overseen significant layoffs across the federal government as part of efficiency initiatives.

Future testing will be closely monitored following the two prior failures of Starship. This will be the first flight utilizing the Super Heavy booster from a previous mission, which successfully returned to Earth.

SpaceX aims for Starship to be a completely reusable system. In three previous test flights, the company successfully executed a spectacular “catch” maneuver, returning the Super Heavy booster to the launch tower’s robotic arm.

The Starship’s most recent flight in early March was cut short after mission control lost contact with the upper vehicle approximately nine minutes post-liftoff.

Footage from Florida and the Caribbean revealed a cloud of smoke, with debris scattered across the sky. The Florida airport issued a temporary ground stop due to “space-fired debris.”

In another test on January 16th, the upper-stage vehicle exploded over the Caribbean, with dust and debris falling on the Turks and Caicos islands; fortunately, local authorities reported no injuries or significant property damage.

The Federal Aviation Administration is conducting an investigation into both incidents and confirmed last week that SpaceX must pause flights again, enlarging the hazard zone along the rocket’s path in accordance with updated safety protocols.

While previous flights had a hazard zone extending 885 nautical miles, Tuesday’s mission will see this area expand to 1,600 nautical miles, affecting the Florida Channel and covering both land and water at launch sites in South Texas, including the Bahamas and Turks and Caicos.

In this latest test flight, SpaceX plans to experiment with various “nominal scenarios” using the Super Heavy booster. Consequently, the first stage will not return to the launch site as part of the catch maneuver. According to the company.

Once in orbit, the upper-stage vehicle will attempt to deploy eight simulated Starlink satellites, which are designed to burn up upon re-entering the Earth’s atmosphere. The mission control team will also aim to re-ignite one of the Raptor engines while in space.

Musk envisions using the spacecraft for future Mars missions, but SpaceX officials indicate that humans will likely complete hundreds of test runs before embarking on journeys with the next-generation rocket.

SpaceX Astronauts Departing from California Coast for Historic Flight

Four civil astronauts concluded their mission on SpaceX vehicles on Friday, landing in waters near Oceanside, California.

This marked the first time the company had brought people back to Earth in the Pacific Ocean after six years of Dragon Capsules splashing down in the Atlantic or Gulf of Mexico.

The FRAM2 mission orbited the Earth for four days in a north-south trajectory, allowing astronauts to witness North and Antarctica directly from space for the first time.

SpaceX relocated its operations to the Pacific Ocean to prevent dragon capsule debris from falling into random parts of the Earth. The vast expanse of the Pacific Ocean and favorable weather along the US West Coast provided a safe and conducive environment for the astronauts’ return.

The first SpaceX Astronaut Mission, a test flight in May 2020, saw Douglas Hurley and NASA’s Robert Behnken launching to the International Space Station. They returned just two months later, splashing down in the Gulf waters off Pensacola, Florida. This mission introduced SpaceX’s upgraded Dragon 2 capsule design.

Subsequently, there were nine NASA-funded flights, five private flights, and ten cargo missions to the International Space Station, all safely landing in Florida.

However, fragments of the spacecraft’s trunk began descending in unexpected locations, such as Australian sheep fields and North Carolina hiking trails. While no injuries or property damage occurred, the continuous rains of space debris pose a risk that needs to be addressed.

SpaceX had initially expected the spacecraft’s trunk to completely burn up during re-entry, but this turned out to be untrue. Therefore, last year, SpaceX announced changes to their Dragon Landing process.

The Dragon Trunk is now abandoned later in the return journey after the spacecraft uses thrusters to deorbit. This ensures targeted debris disposal, with the Pacific Ocean providing a safe area for debris to land without posing a threat to people.

Previously, the Dragon Trunk remained on trajectory for extended periods without a clear prediction of its re-entry location.

The milder Pacific climate also benefits NASA in scheduling missions.

SpaceX’s move partially to the Pacific Ocean for Dragon Landing meets NASA’s requirements for faster processing of scientific experiments returning from space, allowing SpaceX time to prepare for subsequent flights.

The most recent East Coast landing featured a NASA mission returning from the space station with NASA astronauts Suni Williams and Butch Wilmore. Due to issues with the Boeing Starliner spacecraft, their stay in orbit extended over nine months. The mission ended with a playful encounter with a pod of dolphins investigating the spacecraft.

In this week’s FRAM2 mission, Chun Wang, an investor in blockchain and cryptocurrency mining, funded a private mission and chose three companions: Norwegian filmmaker Jannicke Mikkelsen, German robot researcher Laveer Lodge, and Australian explorer Eric Phillips.

Mr. Wang named the mission after the Norwegian ship Fram, which explored the Arctic Circle in the 19th century. He provided updates from orbit, including his experience with space sickness and the uniqueness of Pacific Ocean landings.

“Space motion sickness affected us all – we felt nauseous and vomited several times,” wrote Mr. Wang.

Splashdowns in the Pacific Ocean have historical significance in spaceflight, with most of NASA’s Apollo missions landing there. SpaceX’s return to Pacific landings marks a shift from previous missions primarily landing in Florida.

The curiosity of West Coast dolphins remains to be seen, adding a whimsical touch to the return of space missions.

Rocket explosion by SpaceX causes flight delays at Florida airport due to debris concerns

A huge explosion of a SpaceX rocket above South Florida caused major disruptions for an air traveler due to unexpected delays.

The failure of the SpaceX mission led to the FAA grounding air traffic around Miami, Fort Lauderdale, West Palm Beach, and Orlando, citing concerns about “space-fired debris.”

“After years of traveling, this is a first,” expressed a Facebook user who goes by the name of Rappeck. Executive Peck was flying to South America but had to divert to Miami.

The flight pilot informed passengers that a space rocket had exploded during flight, causing debris to fall along their path. They reassured the passengers that they were safe but needed to circle back to Miami.

Peck shared, “We eventually had to return to Miami. It’s unbelievable. We’ve faced delays due to weather, mechanical issues, and even unruly passengers, but never because of a rocket explosion.”

Jesse Winans, a traveler en route from Costa Rica to Charlotte, found himself in an unexpected layover in Fort Lauderdale along with other passengers.

“They are trying to manage the situation with customers, but I anticipate a long process to reach our destination,” complained the frustrated traveler to NBC South Florida.

SpaceX previously experienced a similar accident in January and has pledged to learn from this latest incident.

The company stated Thursday night in a released statement, “We will analyze data from today’s flight tests to better understand the root causes. Success stems from our learnings, and today’s flights provide more insight to enhance Starship’s reliability.”

Elon Musk summed it up more succinctly with his statement: “Rocket science is hard.”
