About Heterohyus

Heterohyus is an extinct genus of apatemyid from the early to late Eocene. A small, tree-dwelling creature with elongated fore- and middle fingers, in these regards it somewhat resembled a modern-day aye-aye.

Three skeletons have been found at the early Eocene site at Messel Pit, Germany
