Size comparison between a person and Inostrancevia (reconstructed with long lips and some hair). Earlier gorgonopsids in the Middle Permian were quite small, with skull lengths of 10–15 cm (4–6 in), [1] whereas some later genera attained massive, bear-like sizes with the largest being Inostrancevia up to 3.5 m (11 ft) in length and 300 kg (660 lb) in body mass.

Inostrancevia is an extinct genus of large carnivorous therapsids which lived during the Late Permian in what is now European Russia and Southern Africa.The first-known fossils of this gorgonopsian were discovered in the context of a long series of excavations carried out from 1899 to 1914 in the Northern Dvina, Russia.
Other than being four-legged and having a long tail, the gorgonopsian wouldn’t have looked very doglike, Angielczyk said. Similar to reptiles, gorgonopsians didn’t have fur or visible ears, he ...

The Javan rhino (Rhinoceros sondaicus) once roamed across many countries in Southeast Asia. Around 2,000 years ago, they were still common in many parts of China. Around 12,000 years ago, they ...
Rubidgea is a genus of gorgonopsian from the upper Permian of South Africa and Tanzania, containing the species Rubidgea atrox. [1] [2] The generic name Rubidgea is sometimes believed to be derived from the surname of renowned Karoo paleontologist, Professor Bruce Rubidge, who has contributed to much of the research conducted on therapsids of the Karoo Basin.
An enigmatic bipedal creature called Nyasasaurus from Tanzania, known from fragmentary fossils perhaps dating to 240–245 million years ago, represents what the earliest dinosaurs may have looked ...
Saber-toothed mammals have been found almost worldwide from the Eocene epoch to the end of the Pleistocene epoch (42 million years ago – 11,000 years ago). [ 2 ] [ 3 ] [ 4 ] One of the best-known genera is the machairodont or "saber-toothed cat" Smilodon , the species of which, especially S. fatalis , are popularly referred to as "saber ...
