Description

Isocetus was considered a nomen dubium by Steeman (2010) but was treated as a distinct species by Bisconti et al. (2013) based on characters of the mandibular condyle and dentary. A complete thalassothere specimen from Belgium previously assigned to Isocetus depauwi by Abel (1938) is now the holotype of the species Parietobalaena campiniana.^[1][2][3]
