Marepalli (Cretaceous of India)

Where: Andhra Pradesh, India (17.3° N, 77.7° E: paleocoordinates 27.9° S, 58.8° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Infratrappean Beds Formation, Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• "Infratrappean beds", Deccan II phase

•From Malarkodi et al. 2009: Reworked Late Maastrichtian species occur in the Intertrappean beds also and suggest that the reworked species were probably derived from the erosion of the Late Maastrichtian limestone (Infratrappean beds) that were deposited before the arrival of the lower trap lava flows (Keller et al., 2008). Late Maastrichtian age has been assigned to the Doddukuru Infratrappeans beds of the Rajahmundry area on the basis of occurrence of planktic foraminifera.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; pebbly conglomerate and argillaceous marl

• "pebbly conglomerate horizon" and fossiliferous marls

Size class: mesofossils
