The paper deals with some plant fossils collected from three different exposures along the Gopad River Valley near Nidhpur, Sidhi District. The important elements of the assemblages are Sphenopteris sp., Glossopteris (8 spp.), Scutum sp., Vertebraria sp., Taeniopteris sp., Dicroidium (3 spp.) and a few scale- and seed-like bodies. On the basis of the contained plant fossils, the stratigraphic positions of the three exposures have been discussed.
Twenty-one different types of megaspores belonging to 10 genera are recorded from the plant-bearing bed in the upper part of the Tiki Formation exposed in a stream section in Bijouri-Harai area, Shahdol District, Madhya Pradesh (South Rewa Gondwana Basin). Five species are new. The genus Banksisporites Dettmann has been emended and enlarged. On the basis of megaspore study an Upper Triassic age for the plant-bed of the Tiki Formation is supported.
The paper records the first definite ginkgoalean leaf from the Indian Triassic sediments. The leaf is petiolate with semiorbicular lamina, basal angle about 200º and veins generally 1 mm apart. As the leaf is quite different from the known ginkgoalean species, it has been given a new name, viz., Ginkgoites goiraensis sp. nov.
Palynomorphs obtained from a Panchet Group Exposure in the Sukri River, near Kaima, Auranga Coalfield, Bihar are assignable to 31 species and 22 genera. One genus and five species are newly instituted. On the whole the palynological assemblage is dominated by striate bisaccate pollen. Non-striate bisaccate pollen and the pteridophytic spores share nearly equal percentage. The assemblage is quite similar to the Lower Triassic palynological assemblage reported earlier from the Maitur Formation exposed in the Nonia Nala, near Asansol, West Bengal. The Panchet beds near Kaima are therefore believed to represent the Maitur Formation.
A small miofloral assemblage is reported from the beds of the Maitur Formation exposed on the northern bank of the Damodar River near the village Junut, Raniganj Coalfield, West Bengal. Disaccate pollen constitute about 70 per cent of the assemblage. Triletes are only about 10 per cent, while the monosaccates are 15 per cent of the total, qualitatively and quantitatively, the assemblage is akin to the other Lower Triassic palynological assemblages from India.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
