Stratigraphic range: Late Cretaceous
The Trichinopoly Group is a geological formation in India whose strata date back to the Late Cretaceous. It lies between the Ootatoor and Ariyalur groups. It is broad in its southern extremity but thins as it gradually proceeds northwards as it ultimately meets the Ariyalur group. Dinosaur remains are among the fossils that have been recovered from the formation.
