Studies in the Talchir flora of India: 2. Resolution of the spore genus Nuskoisporites Pot. & KL.

Abstract

Spores hitherto assigned to Nuskoisporites Pot. & KI. from the Talchir beds of India have been reinvestigated. Similar material described from the Permian (or Permo-Triassic) sediments of India or other Gondwanaland countries is resurveyed. The study reveals that the Southern (Gondwanaland) spores are organizationally distinct from the Northern Nuskoisporites. They have been, hence, segregated under two new genera, viz. Plicatipollenites and Vikkipollenites. A new Series Apertacorpiti is proposed to receive these genera. The organization of Nuskoisporites is reinterpreted with amendments. The vertical and geographical distribution of the new genera is given with remarks on the question of their probable affinities.
