The Cerro Fortaleza Formation, in older literature described as Pari Aike Formation, is a Late Cretaceous geologic formation of Cenomanian[1] (formerly believed to be Maastrichtian) age of the Austral Basin in southern Patagonia, Argentina.
Description
The sandstones of the formation were deposited in a fluvial environment. The formation has an estimated thickness of 460 metres (1,510 ft) and overlies the Anita Formation, while it is overlain by the La Irene Formation.[2] The giant titanosaur Puertasaurus, the megaraptoran Orkoraptor, Austrocheirus isasii, and the ornithopod Talenkauen have been recovered from the formation alongside turtles and crocodiles.[3]
