The British Geological Survey (BGS) Fossil Focus pages show extracts from a series of guides to the major fossil types. They flourished in the Palaeozoic and Mesozoic, and some survive to the present day. In some fossil crinoids the top of the calyx was a flexible membrane, but in others it is preserved as a rigid dome, All post-Palaeozoic crinoids, including living species, belong to the Articulata, and Problems with understanding the origin and early evolution of the Articulata have arisen because the Permian-Triassic crinoid fossil record is particularly poor.
