The Panchet Formation is an Early Triassic geological formation from the Damodar Valley of India.
It is among the few geological formations outside of Russia, South Africa, and China that documents the recovery of global ecosystems immediately after the Permian-Triassic extinction. It shares similar traits to some of these other formations, including the dominance of Lystrosaurus and the primary predators being proterosuchid reptiles. It also preserves a diversity of temnospondyl amphibians.
