Teilhardina
Teilhardina (/taɪhɑːrˈdiːnə/, teye-har-DEE-nuh)[3] is an extinct marmoset-like omomyid primate that lived in Europe, North America and Asia during the Early Eocene epoch, about 56-47 million years ago.[5] These hypotheses were re-evaluated using new morphological evidence and earliest records of Teilhardina species from the continents concerned.The earliest primates migrated across the Turgai Straits from South Asia to Europe, finally dispersing to North America through Greenland.[9] Teilhardina magnoliana is the earliest known North American primate; its fossil was first discovered in the US state of Mississippi.[1][10] The discoverer, K. Christopher Beard of the Carnegie Museum of Natural History (Pittsburgh, Pennsylvania), posited that Teilhardina magnoliana's ancestors crossed the land bridge from Siberia to the Americas, possibly more than 55.8 million years ago, although the age of the discovered fossil is a matter of disagreement.
