Published 'Giant' predator worms more than half a billion years old discovered in North Greenland



Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.
Published 'Juvenile T. rex' fossils are a distinct species of small tyrannosaur



A new analysis of fossils believed to be juveniles of T. rex now shows they were adults of a small tyrannosaur, with narrower jaws, longer legs, and bigger arms than T. rex. The species, Nanotyrannus lancensis, was first named decades ago but later reinterpreted as a young T. rex. The new study shows Nanotyrannus was a smaller, longer-armed relative of T. rex, with a narrower snout.
Published Insects already had a variety of defense strategies in the Cretaceous



Analyses of amber show that insect larvae were already using a wide variety of tactics to protect themselves from predators 100 million years ago.
Published First high mountain settlers at the start of the Neolithic already engaged in other livestock activities apart from transhumance



An archaeological find in the Huescan Pyrenees allowed researchers to identify for the first time livestock management strategies and feeding practices which demonstrate how the first high mountain societies, at the start of the Neolithic period, were already carrying out complex livestock and farming activities, instead of being limited to the transhumance of sheep and goats.
Published Unveiling ancient secrets: 3D preservation of trilobite soft tissues sheds light on convergent evolution of defensive enrollment



Researchers describe unusual trilobite fossils prepared as thin sections showing the 3D soft tissues during enrollment. The study reveals the soft undersides of enrolled trilobites and the evolutionary mechanism that allows arthropods to enroll their bodies for protection from predators and adverse environmental conditions.
Published Rise of archery in Andes Mountains dated to 5,000 years ago -- earlier than previous research



Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago. The new research from UC Davis indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.
Published Mysterious fruit shown to be the oldest known fossils of the Frankincense and Myrrh family



Early in the 1970s, paleontologists discovered strange fossilized fruits between hardened rock from one of the largest volcanic eruptions in Earth's history. The identity of these fossils remained elusive for the next several decades. Using CT scanning, scientists have now determined they are the oldest fossils from species in the Frankincense and Myrrh family.
Published Mesopotamian bricks unveil the strength of Earth's ancient magnetic field



Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study.
Published AI provides more accurate analysis of prehistoric and modern animals, painting picture of ancient world



A new study of the remains of prehistoric and modern African antelopes found that AI technology accurately identified animals more than 90% of the time compared to humans, who had much lower accuracy rates depending on the expert.
Published Viking dentistry was surprisingly advanced



Widespread caries and toothache -- but also some dental work and filing of front teeth. Viking Age teeth from Varnhem bear witness to surprisingly advanced dentistry.
Published 'A ticking clock': First ground-based survey of damage to Ukrainian cultural sites reveals severity, need for urgency



And after nearly two years of fighting, war is destroying Ukraine’s cultural heritage on a scale not seen since World War II, according to new research.
Published Earliest evidence for domestic yak found using both archaeology, ancient DNA



The high-altitude hero of the Himalayas, yak are among the few large animals that can survive the extremely cold, harsh and oxygen-poor conditions of the Tibetan Plateau. In the mountainous regions of Asia, yak and yak-cattle hybrids serve as vital sources of meat, milk, transportation and fuel. However, little is known about their history: when or where yak were domesticated. In a new study, researchers report archaeologically and genetically confirmed evidence for domestic yak, dating back 2,500 years, by far the oldest record.
Published Best areas for rewilding European bison



Simulations integrate historical records, fossils, and ancient DNA to reveal why the European bison nearly went extinct, and pinpoint optimal areas for conservation. Since the near-extinction of the European bison, enormous conservation efforts have helped to restore wild populations, and its numbers are on the rise. However, the study authors argue that ensuring the species's long-term protection and recovery requires understanding why they nearly went extinct in the first place. 'Our study also suggests areas where rewilding attempts are most likely to be successful,' said lead author July Pilowsky, currently a disease ecologist at Cary Institute of Ecosystem Studies. Pilowsky completed the research while working on their PhD at University of Adelaide and University of Copenhagen.
Published Archaeologists unearth one of earliest known frame saddles



Recovered from looters, a new archaeological discovery from a cave in western Mongolia could change the story of the evolving relationship between humans and horses around the world.
Published This Japanese 'dragon' terrorized ancient seas



Researchers have described a Japanese mosasaur the size of a great white shark that terrorized Pacific seas 72 million years ago. The mosasaur was named for the place where it was found, Wakayama Prefecture. Researchers call it the Wakayama Soryu, which means blue dragon.
Published Molecular fossils shed light on ancient life



Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Published Ancient DNA analysis reveals how the rise and fall of the Roman Empire shifted populations in the Balkans



Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's reign.
Published It turns out, this fossil 'plant' is really a fossil baby turtle



Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.
Published Geoscientists map changes in atmospheric carbon dioxide over past 66 million years



An international consortium of geoscientists has reconstructed atmosphereric levels of carbon dioxide going back 66 million years using proxies in the geoloogical record. Today's concenteration, 420 parts per million, is higher than it's ever been in 14 million years.
Published Baboons in captivity in Ancient Egypt: insights from collection of mummies



Baboons were raised in captivity before being mummified in Ancient Egyptian sites, according to a new study.
