Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[2] The formation is more than {{convert|50|m|ft}} thick and underlies the Calafate Formation and rests on top of the La Irene Formation.[3] See also{{Portal|Geology|Paleontology|Dinosaurs|Cretaceous|Prehistory of South America}}
