Where: India (22.2° N, 78.2° E: paleocoordinates 48.3° S, 51.2° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Denwa Formation, Anisian (247.2 - 242.0 Ma)

• Vertebrate biostratigraphy (e.g. Bandyopadhyay & Sengupta 1999. J. Afr. Earth Sciences 29:233-241) has been used to argue for an early Anisian age for the Denwa, on the basis of similarities to the fauna of the Moenkopi Formation of the USA

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils
