Carbonaceous megaremains from the Neoproterozoic Owk Shales Formation of the Kurnool Group, Andhra Pradesh, India

摘要

An assemblage of carbonaceous compression and impressions recorded from the Owk Shales Formation (OSF) of the Kurnool Group include, Chuarid (Chuaria circularis), Tawuid (Tawuia sp.), Ellypsophysid, Moranid and Beltinid remains. The presence of Chuaria-Tawuia assemblage provides strong evidence of correlation with the assemblage of Rewa and Bhander groups of Vindhyan Supergroup and to some extent with the Halkal Formation of the Bhima Group. Chuaria-Tawuia assemblage is being considered as a potential biostratigraphic marker. In this communication we report varied groups of carbonaceous compression and impressions from the DSF of the Kurnool Group. On the basis of the present fossil assemblage, the OSF is considered to be of the Neoproterozoic age.
