Early Cretaceous flora from the Pranhita-Godavari Basin (east coast of India): taxonomic, taphonomic and palaeoecological considerations

Abstract

AbstractThe Early Cretaceous flora from the Gangapur Formation (Pranhita-Godavari Basin, east coast of India) was studied. Its plant diversity and abundance patterns were examined, and its palaeoecology and environment were interpreted, based on the micro- and macrofloras and sedimentological inputs. The flora is rich and diverse, and consists of bryophytes, pteridophytes, pteridosperms, gymnosperms and angiosperms. The microflora shows higher taxonomic diversity and abundance than the macroflora. Overall, the study indicated an abundance of conifers, particularly Podocarpaceae. The taphocoenosis of the flora comprises local to regional elements derived from riverbank, floodplain, backswamp and valley settings. Taken together, the data on the flora and sedimentology suggest that warm and humid environments prevailed.
