The Panchet Formation is an Early Triassic geological formation from the Damodar Valley of India.[1][2]
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.[3][4]
