Asifabad B (Kotari) (Cretaceous of India)

Where: Andhra Pradesh, India (19.4° N, 79.2° E: paleocoordinates 27.8° S, 60.7° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Maastrichtian (72.1 - 66.0 Ma)

• Coeval to Takli Formation of Nagpur; intertrappean

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; fine-grained, yellow sandstone and white, calcareous sandstone

• 'lacustrine or laggonal conditions with minor fluvial inputs'; 'brackish water as well as freshwater conditions'

•Intertrappean beds

• "calcareous, gritty, white sandstone...measures upto 5m vertically and is unfossiliferous whereas the one overlying the white sandstone is soft, finegrained, pale yellow sandstone...1.5 m thick and yields thin egg shell fragments along with marine microvertebrates"
