Isocetus is an extinct genus of baleen whale belonging to the clade Thalassotherii. Remains have been found in middle Miocene marine deposits in Belgium.
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]
