Abstract

Complete crinoid dorsal cups and crowns are virtually unknown from the Lime Creek Formation and Amana beds except for one partial crown of Dactylocrinus stellatimbasalis (Thomas) 1924. A partial and a complete crown and one dorsal cup belonging to Apodactylocrinus Strimple and Levorson, new genus, are described as A. keithi Strimple and Levorson, n. sp. and A. amanaensis Strimple and Levorson, n. sp.
