Description

Only one skull and some vertebra are known.[3] D. hyaeni is the smallest protocetid from Kutch. Its premolars and molars are about the same size as in other protocetids such as Babiacetus, Rodhocetus and Maiacetus. It has a long, broad snout and high ocular orbits.[4][5]

The genus name comes from the town close by and the species name comes from a local hyena.[1]
