context_page_description: The Carnian is the lowermost stage of the Upper Triassic series. It lasted from 237 to 227 million years ago. The Carnian is preceded by the Ladinian and is followed by the Norian. Its boundaries are not characterized by major extinctions or biotic turnovers, but a climatic event occurred during the Carnian and seems to be associated with important extinctions or biotic radiations.
