Eucetotherium is a genus of cetotheriid mysticete from Miocene (Tortonian) marine deposits in the Russian Caucasus. [1] [2] [3]
Neobalaenidae is a family of baleen whales including the extant pygmy right whale. Although traditionally considered related to balaenids, recent studies by Fordyce and Marx (2013) and Ludovic Dutoit and colleagues (2023) have recovered the living pygmy right whale as a member of Cetotheriidae, making it the only extant cetotheriid. Not all authors agree with this placement.
Cetotherium is an extinct genus of baleen whales from the family Cetotheriidae.
Cetotheriidae is a family of baleen whales. The family is known to have existed from the Late Oligocene to the Early Pleistocene before going extinct. Although some phylogenetic studies conducted by Fordyce & Marx 2013 recovered the living pygmy right whale as a member of Cetotheriidae, making the pygmy right whale the only living cetotheriid, other authors either dispute this placement or recover Neobalaenidae as a sister group to Cetotheriidae.
Parietobalaena is an extinct genus of baleen whale, belonging to the family Pelocetidae. Fossils are found in Miocene-aged marine strata in North America, Europe, Australia, and Japan, including the Temblor and Itahashi formations. Based on previous estimates of juvenile specimens, Tsai (2017) suggested a body size of 12-15 m for P. yamaokai, akin to that of the gray whale.

Piscobalaena is an extinct genus of cetaceans, which lived from the Middle to Late Miocene epochs in Peru and Florida. Its fossils have been found in the Pisco Formation of Peru and the Bone Valley Formation of Florida. At least some individuals of this diminutive whale were preyed on by the shark O. megalodon.
Titanocetus is a genus of extinct cetaceans closely related to the family Cetotheriidae.
Herpetocetus is a genus of cetotheriid mysticete in the subfamily Herpetocetinae. Considerably smaller than modern baleen whales, Herpetocetus measured only 3 to 4 meters in length. Additionally, due to the structure of its jaw, it was unable to open its mouth as wide as modern baleen whales, making it incapable of lunge feeding.
Peripolocetus is a genus of balaenid baleen whale from the middle Miocene of Kern County, California.
Cetotheriopsis is a genus of extinct cetaceans of the family Cetotheriopsidae.
Aglaocetus is a genus of extinct baleen whales known from the Miocene of Patagonia, the US Eastern Seaboard, Japan and the Low Countries. It was once considered a member of Cetotheriidae along with many other putative cetotheres, but was recently recognized as representing a distinct family from true Cetotheriidae.
Metopocetus is an extinct genus of baleen whale belonging to the family Cetotheriidae. The type species is Metopocetus durinasus.
Eomysticetidae is a family of extinct mysticetes belonging to Chaeomysticeti. It is one of two families in the basal chaeomysticete clade Eomysticetoidea.
Tranatocetus is an extinct genus of mysticete from the late Miocene (Tortonian) of Jutland, Denmark. The type and only species is Tranatocetus argillarius.
Brandtocetus is a genus of cetotheriid mysticete in the subfamily Cetotheriinae. The type and only species is Brandtocetus chongulek from the late Miocene (Tortonian) of the Kerch Peninsula in Crimea.
Mithridatocetus is a genus of cetotheriid mysticete in the subfamily Cetotheriinae. Known specimens have been found in marine deposits in Crimea, Ukraine, and the Russian Caucasus.
Kurdalagonus is a genus of cetotheriid mysticete in the subfamily Cetotheriinae from the Miocene of the Russian Caucasus.
Otradnocetus is an extinct genus of baleen whale from the middle Miocene of the Russian Caucasus.
Ciuciulea is a genus of cetotheriid mysticete found in middle Miocene marine deposits in Moldova.
