Carpolestes


Carpolestes, meaning "fruit", and λῃστής 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 like a Malagasy [giant rat] or Pacarana occurring species, C. simpsoni.

Description

Carpolestes had flattened fingernails on its feet but with claws on its fingers. It appears to have been a distant relative of the Plesiadapiformes, such as Plesiadapis.

Palaeobiology

Palaeoecology

Morphologically, Carpolestes supports Robert Sussman's theory 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 plants. The dental microwear of C. dubius and the wedge formed by its mandibular fourth premolar and its trigonid suggests that it was an omnivore with an affinity for frugivory.
