Kentriodontidae is an extinct family ofodontocete whales related to moderndolphins. The Kentriodontidae lived from theOligocene to thePliocene before goingextinct.^[1]

Taxonomy

[edit]

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 ofLipotidae,Brevirostrodelpis is basal to other delphinidans,^[6]Incacetus is probably a member ofInioidea,^[5] andAtocetus andLophocetus have been recovered as a pontoporiid and ziphiid sister taxon respectively, whileHadrodelphis,Kampholophos,Macrokentriodon, andMiminiacetus are recovered in a clade phylogenetically intermediate betweenKentriodon and derived delphinidans ((Inioidea+Lipotidae)+Delphinoidea).^[9] Peredo et al. (2018) restrict Kentriodon toKampholophos,Kentriodon,Rudicetus, andWimahl, and remove Pithanodelphininae and its putative constituent genera (Leptodelphis,Pithanodelphis,Sarmatodelphis,Sophianacetus, andTagicetus) as well asMicrophocaena from Kentriodontidae.^[10]
