Sauropod (Saurischia: Dinosauria) material from the Early Cretaceous Griman Creek Formation of the Surat Basin, Queensland, Australia

Abstract

An isolated ischium and possible neural arch recovered from the lower–middle Albian Griman Creek Formation near Surat, are the only sauropod postcranial elements from that unit in Queensland. This is the southernmost occurrence of sauropod post-cranial remains in eastern Australia. Comparison with other sauropod remains suggests that the ischium might represent an indeterminate titanosaur that is different from taxa previously named from Australia.
