Different primate clades can be identified by their dental formulae. Primates have 2 incisors, and 2-3 premolars (except the aye-aye, which has a very unusual dentition). Most other mammals have either more or fewer teeth. Write the dental formula for each of the craniums or mandibles provided. Remember to write these in the correct standard order

The dentition in mammals is classified into quadrants, starting with quadrant 1 and ending in four:

Quadrant one is the upper right, that is, the right upper jaw teeth, quadrant 2 upper left, 3 lower left and 4 lower right.

The number of teeth is relative to the species or the animal in particular, the number of the quadrant is always put in front, then a point and finally the number of the tooth, for example: if it is the central incisor from the line average would be considered to be piece 1

Explanation:

It is thus then that reference is made to the number of pieces and their location in mammals.

Mammals because of the food they usually have (omnibora) tend to have teeth or molars not so pointed, but flatter, premolars, canines and incisors. Canines are the largest teeth but compared to other species, such as dogs, they are small.

The stimulation of the maxilla during the suckling that characterizes mammals and the eruption of teeth in order and quantity is strongly related.

well, i believe that the answer is 2. : 3
