Abstract

The Jaisalmer basin is an integral part of the major tectonic province and is located towards the west of Aravalli ranges. The lithologies of Jaisalmer basin has been divided into five groups’ viz. Lathi, Jaisalmer, Bedesir (Bhadasar), Pariwar and Abur (Habur) in ascending order. During the present work plant fossils viz. Equisetites, Taeniopteris, Williamsonia, Rhizomopteris, Araucarites and Stachyotaxis were collected from the Bhadasar ridge scarpment section. The assemblage is mostly dominated by conifers with few elements/forms of bennetitales and pteridophytes, which are strongly coeval to Kachchh floral assemblage of Upper Jurassic-Cretaceous age and deposited in shallow marine environment.
