The double rooted lower premolar and primitive wrist morphology can be explained in this way as well.

The lower third premolar is the most commonly affected tooth.

The upper molars are sometimes tricuspid and the lower premolars are relatively simple.

The peculiar shape of their last lower premolar is their most outstanding feature.

When there is excessive height to the lower premolars, the horse has a condition known as ramps.

Also, there was a diastema (gap) between the lower premolars (p2 and p4).

Isolated lower premolars are known from I. kamlialensis.

I tapped a switch in my lower right premolar to cut out the panic-reaction circuit.

The male O. macedoniensis had large canine teeth with shearing lower premolars.

The lower second premolar almost always presents with two lingual cusps.
