TABLE 1. — Cranial measurements (in mm) of Diaphorocetus ortegai n. sp. MUSM 3246 (holotype, Chilcatay Formation, East Pisco Basin, Peru), compared to the type of Diaphorocetus poucheti (Moreno, 1892) MLP 5-6 (Gaiman Formation, Puerto Madryn, Chubut, Argentina). Part of the measurements for MLP 5-6 are taken from Paolucci et al. (2020); others were taken based on photos. Abbreviations: +, incomplete; e, estimate; –, no data.
