FOSSILS BIVALVES FROM THE UPPER BHUBAN FORMATION OF PRAYER POINT, TUIRIAL ROAD, AIZAWL, MIZORAM, INDIA

Abstract

The grey sandstone bed of the Bhuban Formation of Prayer Point, Tuirial Road Aizawl, India, has yielded 26 forms (13 species) of which all of them are bivalves. They are represented by 6 genera that are grouped into 6 families, 3 superfamilies, and 3 orders belonging to 2 subclasses. Out of these 13 species, 3 species could not be identified at the specific level for want of better-preserved materials and more detailed information. A close study of these fossil assemblages reveals that the Upper Bhuban Formation of Prayer Point, Tuirial road Aizawl has a geological age ranging from Aquitanian to Vindobonian, i.e. Middle to Lower Miocene age (~11 to 23 million years).
