About Ectypodus
Ectypodus is an extinct genus of mammals, containing the species E. aphronorus, E. childei, E. musculus, E. lovei, E. powelli, E. szalayi, and E. tardus.
Ectypodus was an arboreal omnivore, living in the Paleocene to Eocene of North America and Europe.
A fossil of E. arctos was found on Ellesmere Island, Canada.
Ectypodus was first described by William Diller Matthew (1871–1930) and Walter W. Granger in 1921.
