Our earliest primate ancestors rapidly spread after dinosaur extinction The small, furry ancestors of all primates — a group that includes humans and other apes — were already taking to the trees a mere 100,000 years after the mass extinction that wiped out the dinosaurs and most other terrestrial animals, according to a new analysis of fossil teeth in the collections of the University of California Museum of Paleontology (UCMP). The analysis showed that the teeth are the earliest-known fossil evidence of any primate, dating from about 65.9 million years ago — 105,000 to 139,000 years a...

(Andrey Atuchin Illustration via Burke Museum) The shapes of fossilized teeth from 65.9 million-year-old, squirrel-like creatures suggest that the branch of the tree of life that gave rise to us humans and other primates flowered while dinosaurs still walked the earth. That’s the claim coming from a team of 10 researchers across the U.S., including biologists at Seattle’s Burke Museum and the University of Washington. In a study published by Royal Society Open Science, the team lays out evidence that a...

(Courtesy of the Burke Museum) Though it doesn’t quite corroborate The Flintstones, a new study featuring UF geology assistant professor Courtney J. Sprain confirms that the earliest known primates did walk with the dinosaurs. Published in Royal Society Open Science, the study analyzed 65.9 million-year-old fossils of the early primate Purgatorius, the oldest genus in a group of primates called plesiadapiforms. The study found that these small mammals, who mainly lived off a diet of insects...

 E-Mail New York, February 24, 2021 - Graduate Center, CUNY/Brooklyn College professor was part of a discovery of the first fossil evidence of any primate, illustrating the earliest steps of primates 66 million years ago following the mass extinction that wiped out all dinosaurs and led to the rise of mammals. Stephen Chester, an assistant professor of anthropology and paleontologist at the Graduate Center, CUNY and Brooklyn College, was part of a team of 10 researchers from across the United States who analyzed several fossils of Purgatorius, the oldest genus in a group of the earliest-know...

Researchers at The University of New Mexico are tied to a new study published in the journal “Royal Society Open Science” that documents the earliest-known fossil evidence of any primate. Associate Professor Jason Moore, of UNM Honors College, and Wade...
