EARLY CRETACEOUS PALYNOMORPHS, DINOFLAGELLATES AND PLANT MEGAFOSSILS FROM THE RAJMAHAL BASIN, JHARKHAND, INDIA

摘要

Palynomorphs, dinoflagellates and plant megafossils are recorded from the intertrappean beds of the Rajmahal Basin, Jharkhand, India. These beds are exposed at Moti Jharna, Sakrigali Ghat, Murali Pahar, Sonajuri and Kalkipara sites. The palynomorphs include Araucariacites, Podocarpidites, Callialasporites, Coptospora, Cyathidites and Balmeisporites. The dinoflagellate taxa observed are Batiacasphaera sp., Dissiliodinium sp. etc. Type A. The floral assemblage consists of Elatocladus sp., Ginkgoites, Sphenopteris, Pachypteris sp., Pterophyllum, Araucaria and Ptilophyllum. The composition of the present assemblage suggests the Early Cretaceous age for these intertrappen sites
