Garjainia is an extinct genus of erythrosuchid archosauriform reptile from the Olenekian of Russia and South Africa.[1] It was approximately 1.5–2 metres (4.9–6.6 ft) long. It contained two species, Garjainia prima from the Yarengian/Yarkenskian Supergorizont of Russia,[2] and Garjainia madiba from the Burgersdorp Formation (Cynognathus Assemblage Zone A) of South Africa.[3] "Vjuskovia triplicostata", a name assigned to some erythrosuchid fossils from Russia,[4] has been synonymized with Garjainia prima.[5][6]
