Where: Madhya Pradesh, India (23.9° N, 81.4° E: paleocoordinates 42.6° S, 51.1° E)
• coordinate stated in text
• small collection-level geographic resolution
When: Tiki Formation (Gondwana Group), Carnian (237.0 - 228.0 Ma)
• "lower part of the Tiki Formation"
•The Tiki Formation is considered a temporal equivalent of the lower Maleri Formation, and both have been correlated on the basis of vertebrate biostratigraphy with the Scaphonyx-Exaeretodon-Herrerasaurus biozone of the Ischigualasto Formation of Argentina and the Hyperodapedon Assemblage Zone of the Santa Maria Formation of Brazil (e.g. Novas et al. 2011. Earth Env. Sci. Trans. Roy. Soc. Edin. 101:333-349). The relevant part of the Ischigualasto Formation has been dated as late Carnian in age on radioisotopic data (e.g. Martinez et al. 2011. Science 331: 206-210), and the Tiki Formation is commonly considered equivalent in age.
