Sivaladapis nagrii


TAXONOMY:

MORPHOLOGY:
Sivaladapis nagrii had a dental formula of 2:1:3:3 on both the upper and lower jaw (Fleagle, 1988). The first molars were the first permanent teeth to erupt in this species (Gingerich and Sahni, 1984; cited in Martin, 1990). The molars and premolars have sharp shearing crests (Fleagle, 1988). The upper molars are considered to be simple with having no hypocone (Fleagle, 1988). This species had an average body mass of around 2.7 kilograms (Fleagle, 1988).

RANGE:
Sivaladapis nagrii was found in India and occurred during the late Miocene (Fleagle, 1988).

DIET:
Based on dental morphology, the high shearing crests of the molars and premolars, this species most likely had a folivorous diet (Fleagle, 1988).
