Abstract

Palynological succession representing Permian to Early Cretaceous sequence through bore-hole no. RJNE-32 drilled (near Mirzachowki) in Rajmahal Basin revealed that the angiospermous pollen make their first appearance in the first intertrappean bed. These forms are assigned to Retimonocolpites peroreticulatus, Aff. Clavatipollenites sp. 1, cf. Stephanocolpites sp., Retimonocolpites sp., Liliacidites sp. and cf. Stellatopollis sp. They are associated with the typical Early Cretaceous palynoassemblage. This is the first record of Early Cretaceous reticulate monosulcate and colpoidate angiospermous pollen from India.
