The generic name refers to the fact that the type locality, Iga, was a training center in Japan for ninja warriors.[1] DescriptionNinjadelphis 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]References1. ^1 Toshiyuki Kimura and Lawrence G.
