Phoberodon is a genus of archaic odontocete cetacean from the Early Miocene (Burdigalian) of Patagonia, Argentina.
Phoberodon was described in 1926 from a partially complete skeleton with skull (holotype MLP 5-4) lacking the earbones, which was found in the Colhuehuapian Gaiman Formation of Chubut Province, Argentina. [1] Subsequent authors either followed Cabrera (1926) in classifying Phoberodon as a squalodontid, or considered it a relative of Waipatia although the genus was included in any cladistic analysis of archaic odontocetes. [2] [3] [4] [5] However, known specimens lack a periotic, which incorporates most defining synapomorphies of Squalodontidae, and Viglino et al. (2018) recovered Phoberodon as distantly related to Squalodon . [6]
Squalodon is an extinct genus of whales of the Oligocene and Miocene epochs, belonging to the family Squalodontidae. Named by Jean-Pierre Sylvestre de Grateloup in 1840, it was originally believed to be an iguanodontid dinosaur but has since been reclassified. The name Squalodon comes from Squalus, a genus of shark. As a result, its name means "shark tooth". Its closest modern relative is the South Asian river dolphin.
Prosqualodon is an extinct genus of Early to Middle Miocene cetacean from Argentina, Australia, New Zealand and Venezuela.
Kentriodon is an extinct genus of toothed whale related to modern-day dolphins. Fossils have been found in North America, Europe and Japan. Several species have been described.
Macrodelphinus is an extinct genus of primitive odontocete known from Early Miocene marine deposits in California.
Waipatia is an extinct genus of odontocetes from the late Oligocene (Chattian) of New Zealand.
Waipatiidae is an extinct family of odontocetes currently known from the Oligocene of the Pacific Ocean and possibly Europe and the Caucasus.
Diaphorocetus is an extinct genus of odontocete cetacean belonging to Physeteroidea. Its remains were found in the Monte León Formation of Argentina, dating to the Early Miocene.
Otekaikea is an extinct genus of toothed whale closely related to Waipatia. It is known from the late Oligocene (Chattian) of New Zealand.
Atocetus is an extinct genus of pontoporiid dolphin found in Miocene-age marine deposits in Peru and California.
Microcetus is a genus of extinct odontocete from the late Oligocene (Chattian) of Nordrhein-Westfalen, Germany.
Notocetus is an extinct genus of river dolphin belonging to Squalodelphinidae. Known specimens have been found in Early Miocene marine deposits from Argentina, Italy and Peru.
Lophocetus is an extinct genus of dolphin belonging to the clade Delphinida that is known from late Miocene (Tortonian) marine deposits in California and Maryland. Although usually placed in Kentriodontidae, recent studies have found it only distantly related to Kentriodon.
Squaloziphius is an extinct genus of odontocete cetacean from the Early Miocene (Aquitanian) aged marine deposits in Washington state.
Agorophius is an extinct genus of toothed whale that lived during the Oligocene period, approximately 32 million years ago, in the waters off what is now South Carolina.
Xenorophus is a genus of primitive odontocete from late Oligocene (Chattian) marine deposits in South Carolina. It belongs to the Xenorophidae.
Morenocetus is an extinct genus of primitive balaenid from the Early Miocene Gaiman Formation of Patagonia, Argentina.
Idiorophus is a genus of extinct toothed whales in the family Physeteridae. Fossils have been found in the Colhuehuapian Gaiman Formation of Argentina and the Libano Sandstone in Italy.
Inticetus is an extinct genus of Early Miocene odontocete from the Chilcatay Formation, Pisco Basin, Peru.
The Gaiman Formation, in older literature also referred to as Patagonian Marine Formation, is a fossiliferous geologic formation of the Peninsula Valdés Basin in the eastern Chubut Province of northwestern Patagonia, eastern Argentina.
