Microbiota and Catagraphs from the Varikunta area of Cuddapah supergroup

Abstract

Cryptarchs namely Granomarginata, Lophosphaeridium and Protoleiosphaeridium belonging to Sphaeromorphitae and catagraphs - Vesicularites and Conferta - are recorded from the subsurface samples of the Cuddapah Supergroup. The catagraphs are supposed to be formed by the exobiogenic activities of Cyanophyceae and bacteria. No comment on the age could be made on the basis of poor occurrence of biota, as they show wide geological distribution from Late Proterozoic to Devonian.
