Today, the stalked forms are known only from deep water habitats, w The resulting carbonate ramps during the Mississippian had improved circulation, producing stenohaline conditions that resulted in an abundance peak for crinoids, recorded by widespread regional encrinites on multiple continents. This increased habitat space was ideal for camerate crinoids and resulted in a new radiation of camerate crinoids.Habitat, distribution, depth range and localities in Cuba are reported for each species.
