The Sanga do Cabral Formation is an Early Triassic sedimentary rock formation found in Rio Grande do Sul, Brazil.^[1]

Description[]

This rock formation is located in the geopark of Paleorrota, and is located to the south of another geopark. The formation dates to 249 million years ago and belongs to the Lower Triassic.^[2]

The Sanga do Cabral Formation is correlated with the "impoverished zone" (Procolophon subzone) of the Lystrosaurus Assemblage Zone of the Karoo Basin of South Africa by some authors on the basis of the abundant records of Procolophon.

Fossil content[]

Among others, the following fossils have been reported from the formation:^[3]

• Elessaurus gondwanoccidens
• Procolophon trigoniceps^[4]
• Sangaia lavinai^[5]
• Teyujagua paradoxa
• ^[6]
• Cynodontia indet.
• ^[7]
• Temnospondyli indet.
