This Crinoid is actually an animal related to modern day starfish so they are echinoderms. They have modern relatives also crinoids that live in the deep oceans today. So then they lived in shallow salt water seas and lagoons. They lived during the Paleozoic and were most prevalent during the Mississippian Period.
