Description
Macrosqualodelphis is distinguished from other squalodelphinids by its larger size ({{convert|3.5|m|ft}}) and a less abrupt anterior tapering of rostrum in dorsal view, U-shaped left antorbital notch prominent nuchal crest higher than the frontals and nasals at the vertex, a thinner, blade-like lateral margin of the posterior portion of the rostrum, and a more voluminous temporal fossa and larger teeth.Giovanni Bianucci, Giulia Bosio, Elisa Malinverno, Christian de Muizon, Igor M.
