Archaeologists Uncover New Insights into the Construction and Purpose of the Gobi Walls

The Gobi Wall is a 321 km long edifice constructed from soil, stone, and wood, located in the Gobi Highlands desert of Mongolia. It represents the least understood segment of the medieval wall system that extends from China to Mongolia. In a recent study, archaeologists sought to uncover information about the builders, purpose, and timeline of this structure. Their findings indicate that the principal structure and its usage evolved during the Xi Xia dynasty (1038-1227 CE), a time notable for its sophisticated frontier defense systems and significant geopolitical transformations.

Stretching 321 km through Mongolia’s highland desert, the Gobi Wall forms part of a comprehensive wall system that once extended across China to Mongolia.

Previously, its origins, functions, and historical significance remained largely uncharted.

“The medieval wall system spans roughly 4,000 km across the vast territories of northern China and Mongolia, making it a distinct segment of Siberia,” remarked Professor Gideon Sheraha Ravi from Hebrew University and his collaborators.

“It stands out as one of East Asia’s most expansive yet mysterious architectural structures.”

“In recent years, numerous projects have delved into various sections of this wall line, yielding substantial research findings.”

“Such studies have established that this extensive system of earthen walls was constructed by different empires from the 10th to the 13th centuries.”

“Among the various parts of the system, the segment within the Gobi Desert in southern Mongolia is the least explored and, as of yet, unrecognized.”

“Our investigation concentrates on a 321-km segment of this wall line in the Omnogovi region of Mongolia, which we refer to as the Gobi Wall.”

In this study, Professor Shelach-Lavi and his co-authors uncovered new insights into the building and purposes of the wall.

They found that the wall and its associated garrison were primarily constructed during the Xi Xia period (1038-1227 CE), a dynasty governed by the Tangot peoples in western China and southern Mongolia.

This era is marked by the growth of frontier defense strategies amid considerable geopolitical upheaval.

Contrary to conventional perspectives that view walls solely as defensive constructions, this research emphasizes the multifaceted roles of the Gobi walls in boundary integration, resource regulation, and imperial governance.

While the main construction and habitation phases align with the Xi Xia dynasty, the research also refuted evidence for consistent habitation of this remote area from the 2nd century BC to the 19th century AD.

The fortress comprises a plunging earth foundation bolstered by stone and wooden reinforcements, showcasing the adaptive use of local materials within this arid, isolated setting.

Additionally, ecological and spatial assessments from this study indicate that the wall routes were strategically selected based on resource accessibility, particularly water and timber.

The fort’s location and garrison positioning utilized natural geographical features such as mountain paths and sand dunes to enhance the wall’s effectiveness.

“This study challenges long-held beliefs regarding the empire’s frontier systems in Asia,” stated Professor Sheraha Ravi.

“The Gobi Wall was not merely a barrier, but an adaptive mechanism for regulating movement, commerce, and territorial authority in a demanding environment.”

This finding sheds light on how environmental adaptation and state power interacted within medieval empires, offering broader insights into ancient infrastructure and its relevance to contemporary political and ecological contexts.

“This study advocates for a wider rethinking of medieval frontiers, not just as static defensive barriers, but as dynamic management frameworks,” asserted the archaeologist.

“The Gobi Wall illustrates the Xi Xia Statecraft model, which uses architectural endeavors to manage population dynamics and territorial delineations.”

“Such an understanding aligns with a theoretical framework that perceives frontiers as zones of control and interaction, rather than rigid dividers, prompting a broader comparative analysis throughout Eurasia.”

The findings were published in a paper in the journal land.

90-Million-Year-Old Mammal Fossils Discovered in the Gobi Desert

Scientists have discovered a new genus and species of ZheLestid mammals from fossil sites in the Bien Series Formation located in the Gobi Desert, Mongolia.

This new species, named ravjaa ishiii, existed during the Cretaceous period approximately 90 million years ago.

The ancient mammals are mouse-sized; the ZheLestidae family of Eutherian mammals was widely found across Eurasia and North America in the late Cretaceous period.

“The remarkably preserved mammal fossils found in late Cretaceous deposits of the Gobi Desert have been crucial for understanding the evolution of Mesozoic mammals,” stated Tsukasa Okosi, a PhD candidate in Science at Okayama University, and a collaborator on the research.

“These extraordinary mammal fossils were primarily excavated from the Balungoyacht and Djadokhta formations, with only two fragmentary fossils obtained from the underlying Baianshiree formation.”

The new Zhelestid fossil was uncovered in 2019 in the Bayan Shiree area within the Bayanshiree Formation.

This specimen consists of the distal section of a premolar and part of a mandible, measuring 1 cm from the first to third molar.

“Discovering such a tiny fossil in the vastness of the Gobi Desert feels like a gift from nature. It’s truly miraculous,” remarked a professor from Okayama University of Science.

“Their exceptionally tall molars and unique jaw structures set them apart from known relatives, prompting us to establish a new genus and species,” explained the paleontologist.

“The robust nature of their molars is reminiscent of seed and fruit-eating mammals, which provides fascinating insights into how early mammalian species may have exploited plant resources.”

The research team asserts that ravjaa ishiii is the first Zhelestid identified from the Bien Series formation, indeed marking the first discovery of its kind in Mongolia.

ravjaa ishiii may represent the oldest member of the Zhelestids, as the currently oldest known Zhelestids were found in Uzbekistan, indicating that this group’s emergence dates back to the early/late Cretaceous boundary,” the researchers noted.

Their study is published online in the journal Acta Palaeontologica Polonica.

Non-biologist uncovers evidence of a massive Hadrosaurus dinosaur in the Gobi Desert

Anti-Japanese and Mongolian paleontologists have found the footprints of Hadrosaurus dinosaur fossils eating large plants from the Cretaceous.

The newly discovered Hadrosaurus footprint dates back about 70 million years ago (Cretaceous).

One of them is about 92 cm in diameter (3 feet), one of the largest Hadrosaurus footprints found so far.

“It is thought that the biggest footprint belongs to the giant SaurolovsIt is estimated that the overall length of the whole body exceeds 15 m (50 feet), and evenly Tyrannosaurus and Turbo saurus Team leader of size Shinobu IshigakiOkayama Science University Dinosaur Museum Research Bureau, and his colleagues stated in a statement.

Saurolovs Is a large Hadrosaurus dinosaur known by the Canadian horseshoe canyon and the Mongolian Nemegut layer.

According to an old-fashioned scholar, it is one of the few dinosaur genus from multiple continents.

“Our discovery suggests that one of the largest bipedal behaviors known so far lived in Mongolia, and also enhances hope for the discovery of large-scale skeletal archeological sites. They say. “

In addition, researchers have found a 24 m (79-foot) trackway composed of about 85 cm (2.8 feet) fossils (2.8 feet).

“From June 1 to 15, 2024, we conducted a follow-up survey in the Nishi Gobi Desert,” he said.

“As a result, we discovered a new trackway, including three footprints of the largest Hadrosaurus discovered so far and 13 fossiled footprint sequences.”

“The identification of 14 trackways, including those found before 2018, enables analysis of posture, walking style, speed, and group movements. This is an unpredictable details.”

“So far, the largest known Hadrosaurus skeleton belongs. Shunton SaurusThey were found in Shandong Province, China. “

“However, the latest discovery in Mongolia suggests the possibility of clarifying large-scale skeletal archeological sites in this area.”

“Our next goal is to clarify a large full skeleton. Saurolovs I will be in charge of these footprints, “said Dr. Ishikawa.
