Nosmips

Nosmips aenigmaticus is a rare fossil primate known only from 12 teeth. Most teeth were found at a site in the Fayum Depression about 40 miles (64 km) outside Cairo, Egypt.[3]

Nosmips aenigmaticus probably lived 37 million years ago in Africa and has not been successfully classified within any group of primates.[4] In particular, it is distinct from the three main branches of primate found in Africa at the time - anthropoids, adapiforms and lemuriforms. It is weakly associated with the Eosimiidae. Its premolars are specialised and the tooth enamel displays extensive signs of pitting, which would appear to be consistent with a diet of either seeds or fruits with hard pits.[5]

Name

Nosmips is an anagram of Simpson. The name was chosen to honour paleontologist and anagram enthusiast George Gaylord Simpson.
