Phoberodon is a genus of archaic odontocete cetacean from the Early Miocene (Burdigalian) of Patagonia, Argentina.

Taxonomy and description

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.
