A Review on Some Gymnospermous Fructifications from the Triassic of Nidpur, Madhya Pradesh, India

Abstract

The Nidpur bed was discovered near Nidpur village, Sidhi District, Madhya Pradesh, India. The carbonized fossils of Nidpur beds comprise plant remains assignable to different groups of the plant kingdom like algae, bryophytes, pteridophytes and gymnosperms. The gymnospermous remains often occur as detached fragments on the shale surface. The most common megafossil on Nidpur shale is the leaf genus Dicroidium which is represented by several species. The review article describes diversity in structurally preserved gymnospermous fructifications Nidistrobus, Nidianthus, Nidpuria, Chakrea, Rugatheca and Lelestrobus from the same Triassic beds of Nidpur, Madhya Pradesh, India. All the fructifications differed in morphological and anatomical features.
