Traces of prehistoric human occupation found in lava tube

Published

on

A study led by Griffith University’s Australian Research Centre for Human Evolution (ARCHE) has uncovered traces of prehistoric human occupation in a lava tube in northern Saudi Arabia.

The discovery was made in the Umm Jirsan Cave, which is a 1,500 metre long lava tube in the Harrat Khaybar Lava Field. The age of the lava flow has not been determined, but a 2007 study suggests that it occurred 3 million years BP.

Recent excavations by ARCHE archaeologists have uncovered human activity dating from the Neolithic to the Chalcolithic/Bronze Age periods (~10,000-3,500 years ago), providing new insights into the evolution and historical development of regional human populations.

Pastoralist use of the lava tube and surrounding landscape is attested in rock art and faunal records, suggesting that Umm Jirsan was situated along a pastoral route linking key oases. According to the researchers, it is unlikely that the lava tube served as a permanent place of settlement, instead was used as shade and a source of water for passing herders with their animals.

Excavations have found massive caches of bones from domestic (e.g., caprids, cattle) and wild (e.g., gazelles) animals, which were being processed and/or consumed within the cave interior.

Rock art and faunal records attest to the pastoralist use of the lava tube and surrounding areas, painting a vivid picture of ancient lifeways. Depictions of cattle, sheep, goat and dogs corroborate the prehistoric livestock practices and herd composition of the region.

“Our findings at Umm Jirsan provide a rare glimpse into the lives of ancient peoples in Arabia, revealing repeated phases of human occupation and shedding light on the pastoralist activities that once thrived in this landscape,” said Dr Mathew Stewart, the lead researcher and a Research Fellow at ARCHE.

Researchers find evidence of ceremonial offerings beneath Maya ballcourt

Archaeologists from the University of Cincinnati have found ceremonial offerings beneath a Maya ballcourt in Mexico.

Using environmental DNA analysis, researchers were able to identify a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah.

The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor upon which a ballcourt was built.

Researchers said the ancient Maya likely made a ceremonial offering during the ballcourt’s construction.

“When they erected a new building, they asked the goodwill of the gods to protect the people inhabiting it,” UC Professor David Lentz said. “Some people call it an ensouling ritual, to get a blessing from and appease the gods.”

The research was carried out through Mexico’s National Institute of Anthropology and History in collaboration with researchers from the University of Calgary, the Autonomous University of Campeche and the National Autonomous University of Mexico.

Researchers from 2016 to 2022 worked at Yaxnohcah in Campeche about 9 miles north of the border of Guatemala, where they excavated a small area of a ballcourt.

The ancient Maya played several ball games, including pok-a-tok, which has rules similar to soccer and basketball. Players tried to get a ball through a ring or hoop on a wall.

UC Professor Emeritus Nicholas Dunning said when buildings were expanded or repurposed, as with the ballcourt, the ancient Maya made offerings to bless the site. Archaeologists sometimes find ceramics or jewelry in these offerings along with plants of cultural significance.

“We have known for years from ethnohistorical sources that the Maya also used perishable materials in these offerings, but it is almost impossible to find them archaeologically, which is what makes this discovery using eDNA so extraordinary,” Dunning said.

Ancient plant remains are rarely discovered in tropical climates, where they decompose quickly. But using environmental DNA, researchers were able to identify several types known for their ritual significance.

They discovered evidence of a morning glory called xtabentun, known for its hallucinogenic properties, lancewood, chili peppers and jool, the leaves of which were used to wrap ceremonial offerings.

Botanist and UC Associate Professor Eric Tepe said finding evidence of these plants together in the same tiny sediment sample is telling. He has studied modern plants in the same forests once traveled by the ancient Maya.

“I think the fact that these four plants which have a known cultural importance to the Maya were found in a concentrated sample tells us it was an intentional and purposeful collection under this platform,” Tepe said.

Researchers noted the challenge of trying to interpret a collection of plants through the opaque lens of 2,000 years of prehistory. But Lentz said the findings help add to the story of this sophisticated culture.

Researchers believe the ancient Maya devised water filtration systems and employed conservation-minded forestry practices. But they were helpless against years-long droughts and also are believed to have deforested vast tracts for agriculture.

“We see the yin and yang of human existence in the ancient Maya,” Lentz said. “To me that’s why they’re so fascinating.”

Archaeologists explore submerged Mesolithic site of Bouldnor Cliff

Archaeologists from the University of Warwick are conducting an underwater study to document the submerged Mesolithic site of Bouldnor Cliff before it vanishes due to erosion.

Bouldnor Cliff is situated in the Solent between the Isle of Wight and the southern coast of England. The site was first discovered in 1999 when divers observed a lobster discarding worked flint tools from its burrow on the seabed.

At a time when Britain was cut off from mainland Europe by rising sea levels, the area of the Solent was a river valley inhabited by an advanced Mesolithic community who developed a boat building technology 2,000 years ahead of their time.

The study aims to find new data on the nature of the late Ice Age environment during the development of the Mesolithic era, and the extent of the interaction between the inhabitants of Bouldnor Cliff and Europe, including the exchange of materials.

Professor Robin Allaby, who is leading the expedition, said: “This is an incredible opportunity to understand the lost world in which the Mesolithic developed using the latest techniques before our chance is gone.”

The study will involve a comprehensive palaeoenvironmental analysis, in addition to state-of-the-art techniques such as optical simulated luminescence for constructing ecological profiles. Furthermore, archaeologists intend to recover archaeological artefacts and environmental markers to reconstruct the past environment.

Dr Kinnaird adds: “This is an exciting research project to showcase the new innovations in luminescence dating, which can tell when an object was last exposed to the Sun. The relevance of this technique in writing the narratives for 4000 years of history, at the time that the British coastline was rapidly changing, is huge!”

According to the researchers, these discoveries carry the potential to significantly transform our comprehension of the era when Britain emerged as an island.
