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]
