Genera and Clades


Cetancodontamorpha is a total clade of artiodactyls[1] defined, according to Spaulding et al., as Whippomorpha "plus all extinct taxa more closely related to extant members of Whippomorpha than to any other living species".[2] Attempts have been made to rename the clade Whippomorpha to Cetancodonta, but the former maintains precedent.[3]

Whippomorpha is the crown clade containing Cetacea (whales, dolphins, etc.) and hippopotamuses.[4] According to Spaulding et al., members of the whippomorph stem group (i.e., "stem-whippomorphs") include such taxa as the family Entelodontidae and the genus Andrewsarchus.
