Abstract

Megaspores belonging to the genera Duosporites, Trilaevipillitis, Srivastavaesporites and Trileites are for the first time described from the Talchir Formation of India. The fossils have been found associated with seed cuticles and miospores in typical Talchir siltstones exposed near Birsinghpur Pali in the Johilla Coalfield, Madhya Pradesh. The assemblage is dominated by the genus Duosporites. The megaspores indirectly suggest the existence of Lycopsid plants at least towards the later part of the Talchir times.

External characters as well as the details of the inner sac have been carefully studied. It is suggested that the extent of the trilete trace and the bordering cushions in relation to the inner sac radius constitutes a charcter of taxonomic significance in delimiting megaspore species.
