Abstract

Fragmentary isolated remains of large (up to 20 m or more) sauropods from the Middle Jurassic (Bajocian) Khadir Formation of Khadir Island (Kachchh, W India) are described and compared in detail. Three of the bone fragments (a metacarpal, a first pedal claw and a fibula) can be assigned with confidence to the Camarasauromorpha and represent the oldest known record of that derived dinosaur group. The new finds from western India further close a temporal and geographical gap in our knowledge of sauropods and contribute to understanding their early phylogeny.

Kurzfassung

Isolierte Überreste eines großen (bis zu 20 m oder mehr langen) Sauropoden werden aus der mitteljurassischen (Bajocium) Khadir Formation auf Khadir Island (Kachchh, W Indien) beschrieben und detailliert verglichen. Drei der Knochenfragmente (ein Metacarpale, eine erste Fußklaue und eine Fibula) können mit Sicherheit einem Vertreter der Camarasauromorpha zugeordnet werden und repräsentieren damit den ältesten Nachweis dieser abgeleiteten Dinosaurier-Gruppe. Die neuen Funde aus dem westlichen Indien schließen eine zeitliche und geographische Lücke in unserer Kenntnis der Sauropoden und tragen zum Verständnis ihrer frühen Phylogenie bei.
