PATHOLOGY

Detailed explanation-1: -Teeth in crocodilians are homodont i.e all teeth are similar in shape and thecodont i.e. embedded in the socket.

Detailed explanation-2: -Unlike heterodonts, homodont teeth are of similar size and anatomy and they all perform the same function. It is seen in sharks and crocodiles.

Detailed explanation-3: -So, the correct answer is ‘Thecodont’

Detailed explanation-4: -Crocodylus siamensis specimens were more shape-heterodont than their congenerics, with one individual being the most shape-heterodont in our sample. Several caimanine individuals, and both Osteolaemus tetraspis specimens, also had relatively high shape heterodonty.
