INFO
Lower molars with \" amphilestid\"  cusp pattern differing from those of most other described taxa in having posteriorly curved cusps a and b, and in the presence of a single mesial cusp (identity uncertain) in a median position, rather than cusp e mesiolingually and cusp f mesiolabially.  T. curvicuspis is one of only a few mammals from the Morrison Formation that is not based on remains from Como Quarry 9. It is by far the most poorest known mammal from that formation.
