Studies on the Upper Gondwana of Cutch - 1. Mio and Macrospores

Abstract

The present paper describes mio- and macrospores obtained from the Umia-beds (Uppermost Gondwana horizon) in Cutch (W. India). They are referred to 48 genera and 82 species, of which four genera viz. Baculareticulosporis, Crassimonoletes, Umiaspora, Auriculozonospora, and 40 species are new. The spore-flora is rich in pteridophytic spores and coniferous pollen grains. It has been compared with the other known assemblages from comparable strata. Finally a discussion on the probable age of Umia-beds, based on the study of Sporae dispersae, has been given indicating that these beds closely correspond to the Wealden (Lower Cretaceous) age.
