Middle Triassic tetrapod footprints of southern South America
In South America, tetrapod footprints of Middle Triassic age were only described from the Cuyana (Cerro de las Cabras Formation) and Ischigualasto-Villa Unión (Los Rastros Formation) basins in west-central Argentina. They are scarce and remain mostly undescribed. Their significance and the putative...

In South America, tetrapod footprints of Middle Triassic age were only described from the Cuyana (Cerro de las Cabras Formation) and Ischigualasto-Villa Unión (Los Rastros Formation) basins in west-central Argentina.

Several groups of tetrapods are suggested to be represented, as non-mammalian therapsids, crurotarsal archosaurs and putative dinosaurs. The presence of crurotarsal archosaurs and non-mammalian therapsids in Cerro de las Cabras Formation suggests a tetrapod fauna more diverse than that documented by the known body fossil record. The ichnites described from the Los Rastros Formation are, until now, the only evidence of amniotes in the Ischigualasto-Villa Unión Basin during the deposition of these levels.
