Anteosaurus (meaning "Antaeus lizard") is an extinct genus of large carnivorous dinocephalian synapsid. It lived at the end of the Guadalupian (= Middle Permian) during the Capitanian age, about 265 to 260 million years ago in what is now South Africa. It is mainly known by cranial remains and few postcranial bones.
Olson (1962) notes that the Russian dinocephalian assemblages indicate environments tied to water, and Boonstra considered that the roughly contemporary Anteosaurus was a slinking crocodile-like semi-aquatic form. The long tail, weak limbs, and sprawling posture do indeed suggest some sort of crocodile-like existence.
Skeleton of the anteosaurine Titanophoneus potens: Scientific classification; ... †Anteosaurus; Anteosaurinae is an extinct subfamily of dinocephalian therapsids.
The anteosaur with the most complete skeleton, Titanophoneus, looks nothing like that and very little of the postcranial anatomy of Anteosaurus is known. Compare with my Anteosaurus [8] . I never got around to finishing getting my image reviewed, and looking back at it I'm dissatisfied with it so I might revise it.
The reconstructions of Anteosaurus currently in use give it strange proportions that don't match the one anteosaur known from a substantial portion of the postcranial skeleton, Titanophoneus. I did a reconstruction which does match those proportions.
Anteosauridae is an extinct family of large carnivorous dinocephalian therapsids that are known from the Middle Permian of Asia, Africa, and South America.These animals were by far the largest predators of the Permian period, with skulls reaching 80 cm in length in adult individuals, far larger than the biggest gorgonopsian.
Skeletal and skull diagrams by fishboy86164577, BatmanelVisigodo, Jaime Headden, and Armin Reindl Jaime Headden has recently produced a new Sharovipteryx skeletal for public use, and not long afterwards I was able to convince a few friends of mine to publicly make some of their diagrams freely available for use in Wikipedia as well.
