Pronothodectes


TAXONOMY:

There are three species in the genus Pronothodectes:
MORPHOLOGY:
Pronothodectes has a dental formula of 2:1:3:3 on both the upper and lower jaw (Fleagle, 1988). Members of this genus have procumbent lower incisors and premolars and molars with low crowns (Fleagle, 1988). The upper incisors have a large posterocone towards the back (Conroy, 1990). Pronothodectes jepi had an average body mass of 406 grams and Pronothodectes matthewi had an average body mass of 306 grams (Fleagle, 1988).

RANGE:
Pronothodectes was found in Western North America, more specifically in the states of Montana and Wyoming (Fleagle, 1988). This genus occurred during the middle Paleocene (Fleagle, 1988).

DIET:
Based upon the molars and premolars having low crowns, members of this genus most likely had a omnivorous diet (Fleagle, 1988).
