Kulattur: Raoceras and assoc fauna (Cretaceous of India)

Where: Tamil Nadu, India (11.1° N, 79.0° E: paleocoordinates 44.7° S, 46.4° E)

• coordinate stated in text

When: Anaipadi Calcarenite Member (Garudamangalam Formation), Middle Coniacian (89.3 - 85.8 Ma)

• Formation from Nagendra et al 2018 Stratigraphy 15(4):245–259. Anaipadi Calcarenite yields marine fossils including ammonoids.

• formation-level stratigraphic resolution

Environment/lithology: coastal; sandstone

• Four facies associations are identified in sandstone of the Garudamangalam Formation by Sarkar et al. 2014. These facies associations with genetically different components indicate deposition occurred in the nearshore zone (Sarkar et al. 2014).

Size class: macrofossils
