of zhelestids. Rather than being early ancestors of modern placental mammals—a theory built almost entirely on tooth morphology—these creatures have been reassigned to the Zalambdalestoidea, an extinct lineage of small mammals that thrived during the...

A remarkably preserved 36,000-year-old saber-toothed cub has been discovered with its whiskers and claws intact, revealing features never seen in fossils. A remarkable discovery in Siberia’s permafrost has unveiled the remains of a saber-toothed cat...

implements retains traces of bison blood, suggesting its use in processing animal remains. These tools were located beneath tooth fragments of extinct megafauna, including camels and bison, which have been radiocarbon-dated to approximately 18,250 years...

the culprit, the research team utilized advanced diagnostic criteria, including a detailed evaluation of dental allometry, tooth orientation, and the specific geometry of the bite patterns. By employing TPSdig software to map the dimensions of the...

Science: Reports confirms the count of twenty mammoths, identified primarily through nineteen lower jaws and an isolated tooth. Evidence of a Prehistoric Hunting Ground While skeletons of other species, such as woolly rhinoceroses, horses, reindeer, and...

analysis identified at least 17 distinct people, including women, men, and a child. Physical indicators, such as antemortem tooth loss and evidence of cranial trauma, provided glimpses into the lives of these ancient residents. Continental Ties and...

to as δ13C. When an animal consumes food, this isotopic “fingerprint” is integrated into the minerals of its bones and tooth enamel. In modern terrestrial ecosystems, there is a predictable, modest shift in δ13C values between what an animal eats and...

and highly processed foods can contribute to several health challenges over time: The development of dental caries and tooth decay, especially with frequent snacking. Increased risk of excess weight gain and obesity due to high-calorie, low-nutrient...
