Abstract

The holotype of the prosauropod dinosaurBlikanasaurus cromptoni Galton & van Heerden 1985, a partial hindlimb, is described from the lower Elliot Formation (Red Beds; Carnian, Upper Triassic) of the Eastern Cape, South Africa.Blikanosaurus, along with the sympatricEuskelosaurus andMelanorosaurus, probably represent the oldest record of the Prosauropoda (certainly so for articulated remains). The prosauropod family Blikanasauridae is characterized by a hind-limb that is extremely stocky, especially the metatarsus.Blikanasaurus was an early heavily-built, quadrupedal saurischian, but it was probably not the ancestor for the Sauropoda. The other tetrapods of the lower Elliot Formation are reviewed with particular emphasis on the carnivorous dinosaurAliwalia rex.

Kurzfassung

Der Holotyp (ein unvollständig erhaltenes Hinterbein) des prosauropoden DinosauriersBlikanasaurus cromptoni Galton & van Heerden 1985 wird aus der unteren Elliot Formation (Red Beds, Karn, Obertrias) beschrieben.Blikanasaurus bildet, zusammen mit den sympatrischen GattungenEuskelosaurus undMelanorosaurus, das älteste Vorkommen der Prosauropoda (zumindest was artikulierte Reste betrifft). Die prosauropode Familie Blikanasauridae ist durch ein extrem plumpes Hinterbein — insbesondere im Metatarsus — charakterisiert.Blikanasaurus kann als ein schwergewichtiger quadrupeder Saurischier angesehen werden, steht aber wahrscheinlich nicht in der Vorfahrenlinie zu den Sauropoden. Es wird ein Überblick über die übrigen Tetrapoden der unteren Elliot Formation mit besonderer Berücksichtigung des carnivoren DinosaurierAliwalia rex gegeben.
