What to expect
Kallamedu Fossil Formation
The Kallamedu Formation is a Late Cretaceous (Maastrichtian) rock unit of the Ariyalur Group, laid down in a river (fluvial) setting of siltstones, clays and sandstones. It has yielded dinosaur remains and petrified wood, and the area near Kallamedu village is the reported find-spot of Bruhathkayosaurus, a titanosaur that may have been among the largest land animals ever. The formation is a key terrestrial-dinosaur locality that complements the district's better-known marine fossil beds.
