Ninjadelphis is an extinct genus of river dolphin from the early Miocene ( Burdigalian) of Japan.

The generic name refers to the fact that the type locality, Iga, was a training center in Japan for ninja warriors.^[1]

Description

Ninjadelphis is distinguished from other allodelphinids by having a trapezoidal shaped exposure of frontals on cranial vertex, a nuchal crest partly overhanging posterior end of maxilla, a wider basioccipital, and basioccipital crests widely diverging posteriorly .^[1]
