The first Jurassic assemblage of carnosaurs and sauropods from South America has been recorded in the Callovian-Oxfordian beds of Patagonia. The new genus of carnosaur is related to Allosaurus. The two new genera of sauropods are cetiosaurids, comparable with but different from Cetiosaurus, and more primitive than Haplocanthosaurus.
