A)pterodactyls.
B)saurentians.
C)pterosaurs.
D)archosaurs.
E)plesiodactyls.

Accepted Answer

Birds, dinosaurs, and crocodilians all belong to the group of reptiles called archosaurs, which share common characteristics such as a socket-and-ball joint in their hips and a hole in their skulls behind their eyes. The other choices are incorrect as pterodactyls and pterosaurs belong to a separate group of extinct flying reptiles, and saurentians and plesiodactyls are not valid categories of classification.
