Globally discordant Isocrinida (Crinoidea) migration confirms asynchronous Marine Mesozoic Revolution
The Marine Mesozoic Revolution (MMR, starting ~200 million years ago) changed the ecological structure of sea floor communities due to increased predation pressure. It was thought to have caused the migration of less mobile invertebrates, such as stalked isocrinid crinoids, into deeper marine enviro...
