Abstract

ABSTRACT: This research paper underscores the systematic study of the two species Ptilophyllum cutchense (Morris) Bose and Kasat and Ptilophyllum acutifolium (Morris) Bose and Kasat of the genus Ptilophyllum Morris. These species of the bennettitalean flora have been recorded for the first time from a newly discovered fossiliferous sedimentary succession of the Pariwar Formation cropping out near Serawa Village located at about 2 km west of Sanu Village of the Jaisalmer Basin. The investigated Serawa Section entails extremely rich record of undiversified bennettitalean flora. The Ptilophyllum cutchense of this studied succession also presents its first record from the Pariwar Formation of the Jaisalmer Basin. Ribbed axes are also described in this section. The floral record from the exposure near Serawa Village has been found somewhat different from the floral records made by earlier workers from the other known localities of the Pariwar Formation. The presence of leaf impressions, calcareous nannofossils and bioturbations in the successive horizons of the studied succession indicates the presence of shallow marine condition at the time of deposition of the rock unit under present endeavour.
