The correct answer is “Intertrappean beds – Fossils of sea plants and animals”.
The Intertrappean Beds are a Late Cretaceous and early Paleogene geologic unit in India. These beds are found as interbeds between Deccan Traps layers, including the slightly older Lameta Formation. They consist a number of different subgroups and formations, and span the Cretaceous–Paleogene boundary.
Trap Layer | Depth (in meters) |
---|---|
Middle Trap | 1200 meters approximately |
Lower Trap | 150 meters approximately |
Upper Trap | 450 meters approximately |
