Discovery of Foraminifera from Bilara Group, Jodhpur District, Rajasthan

Abstract

Tertiary foraminifera belonging to Discorbis and Quinqueloculina are discovered by the author from the limestones of Bilara Group of Marwar Supergroup. These rocks are hitherto regarded as unfossiliferous and Neoproterozoic-Eocambrian in age. The present find of foraminifera suggests that the formations are not older than lower Eocene, throwing new light on the age of the Marwar Supergroup from the study area.
