Crinoids of the morphospecies Baryschyr anosus Moore and Jeffords, Cyclocaudex insaturatus Moore and Jeffords, Floricyclus angustimargo Moore and Jeffords, Cyclocion distictus Moore and Jeffords, Lamprosterigma erathense Moore and Jeffords, and Preptopremnum rugosum Moore and Jeffords from Upper Mississippian (Chesterian) and Lower-Middle Pennsylvanian (Morrowano-Desmoinesian) strata are described from the Sierra Santa Teresa, Sonora. The distribution of these morphospecies allowed establishing paleobiogeographic correlations with other crinoids reported from the Carboniferous of northern Mexico in the cerros El Tule, Sierra Las Mesteñas, Sierra Agua Verde in Sonora. They are also correlated with regions of the United States of America such as Texas, Colorado, Illinois, Oklahoma and Kansas belonging to the North American Craton province. Associated with the crinoids, there is an abundant and diverse biota represented by algae, foraminifera-fusulinids, chaetetid-sponges, corals, bryozoansphenestelids, brachiopods-productids and conodonts that developed on the continental edges of the calcareous shelf in tropical seas of the Rheic Ocean during the late Paleozoic.
