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.Ivakhnenko, M.F. Cranial morphology and evolution of Permian Dinomorpha (Eotherapsida) of eastern Europe. Paleontol. J. 42, 859–995 (2008). 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), 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. 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.
