Noniasporites, A new Megaspore genus from the Upper Permian of Raniganj Coalfield

Abstract

The new type of megaspore recovered from the shale of Kumarpur Sandstone Member of the Raniganj Formation is characterize by the presence of a large number of rill-like exoexinals folds in the inter-rays area. The rill-like folds mask the rays of the trilete mark. Another characteristic feature is the apparent absence of a mesosporium.
