Intertrappean Beds
Introduction The '''Intertrappean Beds''' are a Late Cretaceous and Early Paleocene geologic formation in India. The beds are found as interbeds between Deccan Traps layers, including the more diverse Lameta Formation. The formation spans the Cretaceous–Paleogene boundary, and a significant debate exists about whether specific sites belong to the Cretaceous or the Paleocene. Indeterminate theropod and pterosaur remains have been recovered from the formation, as well as dinosaur eggs. The mammal genera ''Deccanolestes'', ''Sahnitherium'', ''Bharattherium'', and'' Kharmerungulatum'' have been recovered from it as well. A rich plant flora is known from the formation.
