“Ancient Hunters: How Mediterranean Hunter-Gatherers Mastered Long-Distance Sea Journeys 8,500 Years Ago”

Evidence shows that hunter-gatherers were crossing at least 100 kilometers (km) of open water to reach the Mediterranean island of Malta 8,500 years ago, a thousand years before the arrival of the first farmers.

The Mediterranean island of Malta has long been considered a pristine natural system, untouched by human presence prior to the dawn of agriculture. However, new evidence suggests that hunter-gatherers were able to cross at least 100 kilometers of open water to reach this remote island as early as 8,500 years ago – a thousand years before the arrival of the first farmers.

A scientific consortium led by Professor Eleanor Scerri of the Max Planck Institute of Geoanthropology (MPI-GEA) and the University of Malta discovered the traces of humans in the form of stone tools, hearths, and cooked food waste at the cave site of Latnija. The researchers found abundant evidence for hunting and cooking wild animals, including Red Deer that were thought to have gone extinct by this point in time.

In addition to this, the team found clear evidence for the exploitation of marine resources, with remains of seal, various fish, edible marine gastropods, crabs, and sea urchins all being cooked. These discoveries raise questions about the extinction of endemic animals on Malta and other small and remote Mediterranean islands, and whether distant Mesolithic communities may have been linked through seafaring.

“The results add a thousand years to Maltese prehistory and force a re-evaluation of the seafaring abilities of Europe’s last hunter-gatherers, as well as their connections and ecosystem impacts,” explains Professor Scerri. The research was supported by Malta’s Superintendence of Cultural Heritage, and funded by the European Research Council and the University of Malta’s Research Excellence Award.

The study not only sheds new light on human migration patterns but also highlights the resourcefulness and seafaring skills of ancient hunter-gatherers in navigating long-distance sea journeys. Their ability to harness natural currents and winds allowed them to traverse vast expanses of water, defying conventional assumptions about their capabilities. This remarkable achievement has significant implications for our understanding of prehistoric human migration patterns and the impact of early humans on the environment.

Unveiling North America’s Oldest Pterosaur: A Triassic Time Capsule Reveals a Diverse Ecosystem

In the remote reaches of Arizona s Petrified Forest National Park, scientists have unearthed North America’s oldest known pterosaur a small, gull-sized flier that once soared above Triassic ecosystems. This exciting find, alongside ancient turtles and armored amphibians, sheds light on a key moment in Earth’s history when older animal groups overlapped with evolutionary newcomers. The remarkably preserved fossils, including over 1,200 specimens, offer a rare glimpse into a vibrant world just before a mass extinction reshaped life on Earth.

The discovery of North America’s oldest known pterosaur has sent shockwaves through the scientific community. A team of researchers led by paleontologist Ben Kligman has unearthed the fossilized jawbone of a new species, Eotephradactylus mcintireae, in the remote Petrified Forest National Park in Arizona. The find dates back to the late Triassic period, around 209 million years ago, and sheds light on a dynamic ecosystem where diverse groups of animals coexisted.

The Owl Rock Member, a geologic outcrop rich in volcanic ash, has allowed researchers to date the site to around 209 million years old. This makes it one of the park’s youngest rocks and provides a unique window into the Triassic period. The exposures of the Owl Rock Member are found in very remote areas, making them less studied than other geological members in the park.

The team discovered over 1,200 individual fossils, including bones, teeth, fish scales, and coprolites (fossilized poop). This assemblage contains 16 different groups of vertebrate animals that once inhabited a diverse ecosystem. The region’s braided rivers were filled with fish, like freshwater sharks and coelacanths, as well as ancient amphibians, some of which grew up to 6 feet long.

The surrounding environment was home to fearsome reptiles that evolved earlier in the Triassic, including armored herbivores and toothy predators that resembled giant crocodiles. Living alongside these strange creatures were a variety of more familiar critters, including relatives of tuataras and early frogs.

One of the most significant finds is the fossils of an ancient turtle with spike-like armor and a shell that could fit inside a shoebox. This tortoise-like animal lived around the same time as the oldest known turtle, whose fossils were previously uncovered in Germany.

The team also discovered a new species of pterosaur, which would have been small enough to comfortably perch on a person’s shoulder. The tooth-studded jaw revealed crucial clues about how the earliest pterosaurs lived. Because the tips of the teeth were worn down, the team concluded that the pterosaur likely fed on the site’s fish, many of which were encased in armor-like scales.

The bonebed is the latest research collaboration between the National Museum of Natural History and Petrified Forest National Park. Smithsonian scientists have collected petrified wood, fossils, and archaeological objects from the region since the turn of the 20th century.

This remarkable discovery has shed new light on the Triassic period and highlights the importance of continued exploration and research in our understanding of ancient ecosystems. The find also underscores the significance of preserving and protecting our natural heritage for future generations.

Unburying the Past: Ancient Footprints Rewrite American History

Footprints found in the ancient lakebeds of White Sands may prove that humans lived in North America 23,000 years ago — much earlier than previously believed. A new study using radiocarbon-dated mud bolsters earlier findings, making it the third line of evidence pointing to this revised timeline.

The discovery of ancient human footprints in New Mexico’s White Sands National Park has sent shockwaves through the archaeological community. The footprints, estimated to be between 23,000 and 21,000 years old, are rewriting American history by suggesting that humans arrived in the Americas much earlier than previously thought.

Vance Holliday, a University of Arizona archaeologist and geologist, first visited White Sands in 2012 as part of a research project. He was invited to examine the geologic layers in trenches dug by previous researchers, but it wasn’t until he asked about a site on the adjacent missile range that the footprints were discovered.

Researchers from Bournemouth University in the United Kingdom and the U.S. National Park Service excavated the footprints in 2019 and published their findings in 2021. However, critics have questioned the dating of the footprints, citing concerns over the reliability of ancient seeds and pollen used to determine the age.

Undeterred, Holliday led a new study that relied on radiocarbon dating using ancient mud instead of seeds and pollen. The results, published today in Science Advances, confirm that the footprints are between 20,700 and 22,400 years old, corroborating the original finding.

The new study marks the third type of material used to date the footprints, with two separate research groups producing a total of 55 consistent radiocarbon dates. As Holliday notes, “It’s a remarkably consistent record.”

While the discovery is significant, it raises questions about why there are no signs of artifacts or settlements left behind by those who made the footprints. Holliday acknowledges that this remains a mystery, but suggests that hunter-gatherers may have been careful not to leave behind any resources in their short time frame.

The discovery of ancient human footprints in White Sands National Park is rewriting American history and has significant implications for our understanding of when humans first arrived in the Americas. As Holliday says, “You get to the point where it’s really hard to explain all this away.”

Debunking the Elite: New DNA Research Challenges Ancient Ireland’s Incestuous Social Hierarchy

DNA from a skull found at Newgrange once sparked theories of a royal incestuous elite in ancient Ireland, but new research reveals no signs of such a hierarchy. Instead, evidence suggests a surprisingly egalitarian farming society that valued collective living and ritual.

The article you provided has been rewritten to improve clarity, structure, and style, making it understandable to a general audience.

In ancient Ireland, around 5,000 years ago, the notion that an incestuous social elite ruled over the people was questioned by new research. The study examined DNA evidence from burials at Newgrange, a prehistoric monument, which previously led to speculation about a ruling class or royal family being buried there.

Researchers analyzed a bone skull fragment found in the chamber and discovered that it belonged to an individual who was likely born of incestuous relationships, but also distantly related to others buried in the same tomb. This finding suggested that only certain individuals were buried in the chamber, implying they held special positions in society.

However, researchers from the University of York and University College Dublin have now shown that there is no evidence of an elite class existing economically or socially among nearby settlements, dietary practices, or trade. They believe that ancient Irish society was more equal, as evidenced by shared resources, similar dwellings, and a lack of large settlement systems or trade mechanisms.

Professor Penny Bickle stated, “The evidence points to a much more collective ethos.” She added, “We can only begin to understand these monuments and tombs if we examine the social lives or the communities that built and used them.”

Newgrange is an ancient monument older than Stonehenge and the Pyramids of Giza, believed to have been built by a farming community in County Meath. The original burial place of the skull fragment, NG10, dated to 3340-3020 BC, was questioned, as its genetic clustering typically reflects distant biological relationships rather than close familial ties.

Associate Professor Jessica Smyth noted that people were selected for burial in passage tombs, but the reasons behind this selection are unknown. She also mentioned that bodies were broken down and mixed with cremated remains before being placed in megalithic monuments, making it unclear who the parents of certain individuals might have been.

Professor Penny Bickle concluded, “It is by no means clear that the monument was the first burial site of NG10.” She added, “As it stands, the incestuous origins of NG10 are a one-off compared to all of the DNA data we have for Neolithic Ireland.”

The research, published in Antiquity, suggests that ancient Irish society might have been more inclusive and equal than previously thought.
