The high eustatic sea level and warm climate of the cretaceous meant a large area of the continents was covered by warm shallow seas the cretaceous was named for the extensive chalk deposits of this age in europe, but in many parts of the world, the cretaceous system consists for a major part of marine limestone, a rock type that is formed under warm, shallow marine circumstances.
