Dinosauriforms
An unnamed guaibasaurid was present in the formation based on associated vertebrae, hip, and hindlimb material, specimens ISI R277. Two more indeterminate dinosauriform species are also known from the formation, based on specimens ISI R282 (a hip and three vertebrae) and ISI R284 (a right ilium similar to that of Nambalia roychowdhurii). Material from the formation has also been referred to Herrerasauridae.

Other amniotes
Phytosaur fossils are known from the formation, including forms similar to Angistorhinus and Leptosuchus. Indeterminate aetosaurs and dicynodonts have also been reported.

Correlations
The formation has been correlated with the Forest Sandstone of Africa, the lower Caturrita Formation of the Paraná Basin in Brazil, the upper Ischigualasto Formation and lower Los Colorados Formation of the Ischigualasto-Villa Unión Basin of Argentina, and the Chinle Formation of North America.
