Carpolestes is a genus of extinct primate-like mammals from the late Paleocene of North America. It first existed around 58 million years ago. The three species of Carpolestes appear to form a lineage, with the earliest occurring species, C. dubius, ancestral to the type species, C. nigridens, which, in turn, was ancestral to the most recently occurring species, C. simpsoni.[1] It had flattened fingernails on its feet but with claws on its fingers.[2] Morphologically it supports Robert Sussman´s theory[3] of the co-evolution of tropical fruiting Angiosperms and early primates where Angiosperms provide nectar and fruits in return for dispersing the seed for tropical rainforest plans. It appears to have been a distant relative of the Plesiadapiforms such as Plesiadapis.
