Pronycticebus was a genus of adapiformes primates that lived during the middle to middle late Eocene. It is represented by two species, Pronycticebus gaudryi and Pronycticebus neglectus,[1] of which an almost complete specimen was found in Germany ,[2] and the Quercy Phosphorites Formation of France.
Morphology
Pronycticebus neglectus possessed what appears to be a grooming claw on the second digit of each foot like modern strepsirhines (Fleagle, 1999) and had a dental formula of 2:1:4:3. Pronycticebus neglectus has a petrosal bulla and a postorbital bar. Pronycticebus neglectus may have been a nocturnal or a crepuscular species, which is suggested by a relatively large orbital size. Pronycticebus neglectus has a relatively large baculum for a species of its size, which had an average body mass of 825 grams.[citation needed]
Range
Pronycticebus neglectus lived in Europe.[2]
Locomotion
Based upon limb morphology, Pronycticebus neglectus moved by quadrupedalism, leaping, and climbing. This species is less of a leaper than the notharctines and used slow quadrupedalism less than the adapines.[3]
