Cyathocrinites from the Silurian (Wenlock) strata of southeastern Indiana Fieldiana, Geology, Vol.35, No.7
Three new species of Cyathocrinites are described from the Laurel Limestone-Waldron Shale succession in southeastern Indiana. The paleoecology of the species is discussed in detail. All Silurian members of Cyathocrinites are reviewed and assigned to three new subgenera (Conicocyathocrinites, Rugosocyathocrinites, and Levicyathocrinites). A phylogeny of the Silurian cyathocrinitids is suggested Includes bibliographical references (p. 133-136) Three new species of Cyathocrinites are described from the Laurel Limestone-Waldron Shale succession in southeastern Indiana.
