Dinomorpha
Extinct clade of therapsids
From Wikipedia, the free encyclopedia
Dinomorpha is a proposed clade of extinct therapsids uniting Biarmosuchia and Dinocephalia to the exclusion of other major therapsid groups. The usage of the grouping was introduced in a paper focusing on early therapsid evolution in eastern Europe.[1] Most phylogentic analysis had supported the alternative, more traditional placement of biarmosuchians and dinocephalians in a pectinate arrangement relative to the clade Neotherapsida (Anomodontia and Theriodontia),[2] a 2026 paper from Duhamel et al. focusing on the phylogenetic relationships of therapsids using exclusively on cranial characters, recovered a clade uniting Biarmosuchia and Dinocephalia.[3] The authors recommended using Ivachnenko (2008) "Dinomorpha" as the available clade name for Biarmosuchia and Dinocephalia, along with using modern definitions for both members in a stem-based manner.[3]
