1995-96 PROJECT I Research Projects and Programmes ANTIQUITY, RADIATION AND EVOLUTIONARY TERNS OF EARLY LIFE PAT­ Programme Ohjective I. I Palaeobiology of Vindhyan Basin To identify metaphytes and metazoan hody ji-Jssils, ichnofossils and their relics from the Proterozoic succession and their evolution and diversification To identify organa-sedimentary stmctures found in association of metaphytes and metazoans and to decipher environmental conditions To determine the significance of metaphytes and metazoans in hiostratigraphy Macroscopic biota comprising Chuaria - Tawuia - Krishnania were studied from the argillaceous sediments of Rohtas Formation, in Bihar, Uttar Pradesh and Madhya Pradesh. The sediments represent topmost part of the Semri Group. Two distinct carbonaceous impressions were identified, both belonging to the family Bryopsidaceae (Chlorophyta). The feather-shaped fomls compare morphologically to Bryopsis and branched filamentous fonus bearing lateral spheroidal stmctures to Derhesia. This evidence supports the presence of Chlorophyta even during ± 1000 Ma years before. New collection was done from the Lower Bhander Limestone Formation exposed around Bainkuiyan, Madhya Pradesh. Another problematic trace fossil showing fine curvature was marked. Additionally a macroscopic foml Sekwia Hofmann (reported from the Vendian of Canada) was recorded. The presence of Sekwia was previously not known from the Indian Precambrian. Examined tubular forms of ichnofossils previously described from the Kaimur. The septate tubular form indicates that it may be representing resting stage of metazoan. Studied 30 samples exposed around Judwani area, Semri Group of Madhya Pradesh both in thin section and maceration. The acritarch and cyanophycean forms arc poorly preserved and highly distorted. P.K.
