The family Adapidae and the related Notharctidae contain two North American genera, Notharctus and Smilodectes, which are well represented in the fossil deposits of the Bridger Basin, Wyoming, U. S. , and Adapis, Europolemur, Anchomomys, and Pronycticebus from Europe. Notharctus and Smilodectes are not thought to be antecedent to living lemurs, eocene primates north america

Mar 11, 2008  Primates and several other modern mammalian groups (including artiodactyls and perissodactyls) first appear in the North American fossil record shortly after the PaleoceneEocene (PE) boundary (13), an interval marked by rapid and dramatic global warming known as the PaleoceneEocene Thermal Maximum (PETM) (1, 46).
