Eight genera and 9 species of crinoids are described for the first time (Pentagonomischus plebeius, Axilinucrinus angustus, Cyclocaudex jucundus, Floricyclus angustimargo, Floricyclus granulosus, Cyclocrista cheneyi, Preptopremnum rugosum, Cycloscapus laevis, and Cyclocaudiculus regularis); they proceed from outcrops of the Pennsylvanian of Sierra Las Mesteñas in northeastern Sonora, Mexico. Associated to the crinoids, fenestellid bryozoans; brachiopods of the genera Anthracospirifer, Linoproductus, Composita, Cleiothyridina, and Antiquatonia; solitary (Lophophyllidium) and colonial (Syringopora) corals; coralline sponges (Chaetetes); fusulinid foraminifera (Fusulina, Triticites); and phylloid algae (Komia, Eugonophyllum, Kamaena y Zidella) were identified. This biota is related with those from the Carboniferous of Sonora (Cerros El Tule and Sierra Agua Verde) and from the United States of America (Texas and Colorado). The community made up by encrusting phylloid algae, fusulinids, corals, bryozoans, brachiopods and crinoids developed in a carbonate platform, shallow tropical-water environment.
