Goio-Erê Formation
Geological formation in Brazil
From Wikipedia, the free encyclopedia
The Goio-Erê Formation is a geological formation in Brazil. It is sometimes thought to be deposited between the Turonian and Campanian stages of the Late Cretaceous,[1] but an Aptian-Albian date has also been proposed.[2][3] It primarily consists of sandstone and was deposited in a desert environment. It is known for its exceptional 3-D preservation of fossils at the Cemitério dos Pterossauros ("Pterosaur Graveyard") Quarry, located in the municipality of Cruzeiro do Oeste.[2][3] Animals recovered from this site include the pterosaurs Keresdrakon, Caiuajara and Torukjara, the dinosaurs Berthasaura and Vespersaurus, and the iguanian lizard Gueragama. A few studies have alternatively assigned the Cemitério dos Pterossauros site to the younger Rio Paraná Formation, however.[4][5]
