A review of the crinoid columnals (Echinodermata-Crinoidea) from the Carboniferous of Mexico. Revista De Biologia Tropical

Abstract: The fossil crinoids and associated fauna from the Carboniferous (Mississippian–Pennsylvanian) of Mexico (Sonora, Tamaulipas, Hidalgo, Puebla, Guerrero, Oaxaca and Chiapas States) are described. Data are based on a combination of field and published sources, including seven previously studied localities from the central and southern areas, and four new localities from the northwestern part of the country. A total of 28 morphospecies are reported, seven from the Mississippian and 21 from the Pennsylvanian. Eleven are recorded for the first time in Mexico. These crinoid columnal morphospecies have been reported from the United State
