Herpetocetus is a genus of cetotheriid mysticete in the subfamily Herpetocetinae.
There are four recognized species of Herpetocetus: H. scaldiensis,[2] H. transatlanticus,[3] H. bramblei,[3] and H. morrowi.[4] An additional unnamed species from Japan has been referred to the nomen dubium Mizuhoptera sendaicus in the past,[5] but the undiagnostic nature of the holotype of the latter means that it cannot be confidently referred to M. sendaicus.[6]
A recently discovered specimen of Herpetocetus from the Lower-Middle Pleistocene (Gelasian) Falor Formation of northern California indicates that Herpetocetus survived into the early Pleistocene, shedding light on the diversity of mysticetes in the early Pleistocene.[7] Since other cetotheriids became extinct by the end of the Neogene, it's therefore possible that some Pliocene representatives of Cetotheriidae made it into the Pleistocene to co-exist with extant mysticete species.
