Langhian (Early Middle Miocene) foraminiferal Assemblage from Bhubhan formation, Mizoram, NE India

A small but varied assemblage of planktonic and benthic foraminifers comprising at least six genera and seven species is documented from the Upper Bhubhan Formation exposed at Thuampui in Aizawl District of Mizoram (NE India). The fossils from Thuampui are generally poorly preserved and some are even deformed, nevertheless they are important for determination of age and paleobathymetry. Based on this foraminiferal assemblage an early Middle Miocene age equivalent to planktonic foraminiferal zones N8-N9 and a paleobathymetry of 50 m is suggested for the fossiliferous Upper Bhubhan Formation at Thuampui of Mizoram.
