Remains of algae from the Indian Precambrian sedimentary sediments, both Archaean and Proterozoic are surveyed. The Precambrian algal forms are preserved either in form of structural biological remains or their exogenous activities, the stromatolites. The structural biological remains are preserved in form of macrofossils and microfossils. Microfossils are referable to Cyanophyceae and Acritarchs. The evidences of algae indicate that cyanophytes are biostratigraphically significant in the Precambrians.
Key words: Preca mbrian, India, Algae, Acritarch and Stromatolites.
