4 km southwest of Tiki Village (Triassic of India)

Also known as near Simaudh village

Where: Madhya Pradesh, India (23.9° N, 81.3° E: paleocoordinates 42.6° S, 51.1° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Lower Tiki Member (Tiki Formation), Carnian (237.0 - 228.0 Ma)

• lower part of 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.

• bed-level stratigraphic resolution

Environment/lithology: fluvial; red, calcareous mudstone

• "The Lower Tiki Formation, about 28-30m thick, is characterized by presence of predominantly reddish mudstone/claystone with thin calcareous intercalations, laminated siltstone, calcarenite, limestone and feldspathic quartzarenite. The non-laminated mudstone beds usually contain calcareous globules, calcified rootlets, calcareous nodules, and small to large concretions. The Upper Tiki Formation overlying the conglomerate bed containing lime-pellet comprises mainly of sandstone and reddish mudstone which are deposited as an alternate sequence. Fossils are mainly recorded from the lower Tiki Formation. The unionid bivalve consisting beds act as marker for the fossiliferous horizons of Lower Tiki Formation." - Kumar and Sharma (2019)
