Stratigraphy
Formation:Infratrappean Beds
Stratigraphic resolution:bed
Stratigraphy comments: "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.
