Is an Anteosaurus a dinosaur?

Despite its name and fierce appearance, Anteosaurus is not a dinosaur but rather belongs to the dinocephalians–mammal-like reptiles predating the dinosaurs.

When did the Anteosaurus go extinct?

266-260 million years ago
Anteosaurus (meaning “previous or early reptile”) is the name given to an extinct genus of large carnivorous mammal-like reptile. It lived during the Capitanian epoch of the Middle Permian (266-260 million years ago) in what is now South Africa. They became extinct by the middle Late Permian.

How big was the Anteosaurus?

It was perhaps the largest known carnivorous non-mammalian synapsid, estimated at 5–6 m (16–20 ft) in length and 500 to 600 kg (1,100 to 1,300 lb) in weight. The teeth are another identifying characteristic of Anteosaurus.

What did Anteosaurus eat?

Representing the pinnacle of dinocephalian predator evolution, Anteosaurus (‘the before or early reptile’ – skull 65cm) shared the heat-conserving body features of its plant-eating kin. Almost as big as its prey, poor Struthio- cephalus (‘ostrich head’ – skull 80cm), Anteosaurus was likely a brute force hunter.

Why did the Anteosaur go extinct?

Geological evidence indicates that dinosaurs became extinct at the boundary between the Cretaceous and Paleogene eras, about 66 million years ago, at a time when there was worldwide environmental change resulting from the impact of a large celestial object with the Earth and/or from vast volcanic eruptions.

Why did Anteosaurus go extinct?

How did Protosuchus get its name?

A bit of trivia‭ ‬about Protosuchus ,‭ ‬when first described by the famous American palaeontologist Barnum Brown the holotype specimen had been named Archaeosuchus .‭ ‬However it was soon learned that this name had already been given to a genus of synapsid by the South African palaeontologist Robert Broom,‭ ‬hence the reason for the name change.

Is Eccasaurus a true anteosaur?

Eccasaurus, with a holotype of which the cranial material consists of only few typical anteosaurid incisors, appears to be only determinable as to family. The skull fragment forming the holotype of Pseudanteosaurus can best be considered as an immature specimen of Anteosaurus.
