TL;DR: A critical taxonomic review of all known anteosaur taxa and a reevaluation of anteosurian interrelationships recovers a monophyletic Anteosauridae containing two major clades, Syodontinae (containing Australosyodon, Notosydon and Syodon) and AnteOSaurinee ( containing Anteosaurus, Sinophoneus and Titanophoneus).
Abstract: Anteosaurs (Therapsida: Dinocephalia: Anteosauria) were the dominant terrestrial predators during the late Middle Permian period and are known from southern Africa, the former USSR, China and Brazil. This paper presents a critical taxonomic review of all known anteosaur taxa and a reevaluation of anteosaurian interrelationships. The following anteosaur species are considered to be valid: Anteosaurus magnificus, Archaeosyodon praeventor, Australosyodon nyaphuli, Microsyodon orlovi, Notosyodon gusevi, Sinophoneus yumenensis, Syodon biarmicum, Titanophoneus adamanteus and T. potens. Syodon efremovi is considered a junior synonym of S. biarmicum, Stenocybus acidentatus to represent juvenile material of Sinophoneus yumenensis, Doliosauriscus yanshinovi a junior synonym of Titanophoneus potens, and Paranteosaurus primus a junior synonym of Anteosaurus magnificus. Admetophoneus kargalensis, Archaeosuchus cairncrossi, Brithopus bashkyricus, B. ponderus, B. priscus, Eccasaurus priscus, Lamiasaurus newtoni and Orth...

TL;DR: Phylogenetic analysis indicates that the Brazilian dinocephalian occupies a middle position within the Anteosauridae, reinforcing the model of a global distribution for therapsids as early as the Guadalupian.
Abstract: The medial Permian (∼270–260 Ma: Guadalupian) was a time of important tetrapod faunal changes, in particular reflecting a turnover from pelycosaurian- to therapsid-grade synapsids. Until now, most knowledge on tetrapod distribution during the medial Permian has come from fossils found in the South African Karoo and the Russian Platform, whereas other areas of Pangaea are still poorly known. We present evidence for the presence of a terrestrial carnivorous vertebrate from the Middle Permian of South America based on a complete skull. Pampaphoneus biccai gen. et sp. nov. was a dinocephalian “mammal-like reptile” member of the Anteosauridae, an early therapsid predator clade known only from the Middle Permian of Russia, Kazakhstan, China, and South Africa. The genus is characterized, among other features, by postorbital bosses, short, bulbous postcanines, and strongly recurved canines. Phylogenetic analysis indicates that the Brazilian dinocephalian occupies a middle position within the Anteosauridae, reinforcing the model of a global distribution for therapsids as early as the Guadalupian. The close phylogenetic relationship of the Brazilian species to dinocephalians from South Africa and the Russian Platform suggests a closer faunistic relationship between South America and eastern Europe than previously thought, lending support to a Pangaea B-type continental reconstruction.

TL;DR: The recent discovery of anteosaurid dinocephalians in China has important implications for the biostratigraphic distribution of these early therapsids and has furthermore revealed additional autapomorphies of the Anteosauridae.
Abstract: Dinocephalian mammal-like reptiles have in the past been known only from Russia and South Africa. The recent discovery of anteosaurid dinocephalians in China has important implications for the biostratigraphic distribution of these early therapsids and has furthermore revealed additional autapomorphies of the Anteosauridae.
