Kentriodontidae is an extinct family of odontocete whales related to modern dolphins. The Kentriodontidae lived from the Oligocene to the Pliocene before going extinct. [1]
Kentriodontids have been variously divided into three or four subfamilies: Kampholophinae, Kentriodontinae, Lophocetinae, and Pithanodelphinae. [1] However, some cladistic studies have recovered Kentriodontidae as paraphyletic [2] [3] [4] [5] [6] while others have recovered the family as monophyletic. [7] [8]
For instance, Miminiacetus may be a close relative of Lipotidae, Brevirostrodelpis is basal to other delphinidans, [6] Incacetus is probably a member of Inioidea, [5] and Atocetus and Lophocetus have been recovered as a pontoporiid and ziphiid sister taxon respectively, while Hadrodelphis, Kampholophos, Macrokentriodon, and Miminiacetus are recovered in a clade phylogenetically intermediate between Kentriodon and derived delphinidans ((Inioidea+Lipotidae)+Delphinoidea). [9] Peredo et al. (2018) restrict Kentriodon to Kampholophos, Kentriodon, Rudicetus, and Wimahl, and remove Pithanodelphininae and its putative constituent genera ( Leptodelphis, Pithanodelphis, Sarmatodelphis, Sophianacetus, and Tagicetus) as well as Microphocaena from Kentriodontidae.
