Calcareous skeletal algae belonging to Cyanophyta (Cyanobacteria), Chlorophyta and Rhodophyta are known from Uttatur, Trichinopoly, Ariyalur and Niniyur groups of Tiruchirapalli District, Tamil Nadu. An attempt has been made to analyse the algal assemblages across the Cretaceous-Tertiary sequence in Tiruchirapalli District, Tamil Nadu. The distribution pattern of algal taxa indicates that there is a gradual change in algal flora from Cretaceous to Tertiary.
