Capitanian genus extinctions

Ulemosaurus is an extinct genus of dinocephalian therapsids that lived 265 to 260 million years ago, at Isheevo in Russian Tatarstan. It was a tapinocephalid, a group of bulky herbivores which flourished in the Middle Permian. Ulemosaurus and other tapinocephalians disappeared at the end of the Middle Permian.

Bradysaurus is a genus of large, primitive and widespread pareiasaur. They possessed a covering of armoured scutes, likely serving as defense against their main predators, the gorgonopsians.

Deuterosaurus is an extinct genus of dinocephalian therapsids, one of the non-mammalian synapsids dominating the land during the late Paleozoic.

thumb|left|Restoration of H. boonstrai Hipposaurus ('horse lizard') is an extinct genus of basal therapsids known from the Tapinocephalus Assemblage Zone of the Main Karoo Basin, South Africa. Chronologically this is within the Capitanian stage of the Guadalupian Series (Middle Permian). The genus was first described by S.H. Haughton as H. boonstrai on the basis of a skull and associated skeleton and was later considered a gorgonopsian in the family 'Ictidorhinidae' by Robert Broom. It is now considered a basal biarmosuchian, but its affinities remain uncertain. Some authors note the similari

Keratocephalus ("horned head") is an extinct genus of tapinocephalian therapsids from the early Capitanian age of South Africa.

Struthiocephalus ("ostrich head") is an extinct genus of dinocephalian therapsids from the Permian of South Africa. It was a large animal, reaching in body mass.

Eriphostoma is an extinct genus of gorgonopsian therapsids known from the Middle Permian (middle Capitanian stage) of Tapinocephalus Assemblage Zone, South Africa. It has one known species, Eriphostoma microdon, and was first named by Robert Broom in 1911. It is one the oldest known gorgonopsian and among the smallest and most basal members of the clade.
