Costalocrinus ibericus n. sp. is morphologically similar to Barycrinus rhombiferus ( Owen and Shumard, 1852 ) from the Mississippian, except for the characters of the anal X plate and degree of calcification of the anal sac. These two species are separated by approximately 55 m.y. and provide evidence of slow...
