Supplementary data for: A Silurian (Homerian) pelmatozoan echinoderm fauna from west-central Ohio

A diverse echinoderm fauna lived in reef and non-reef Silurian facies of the upper Midwestern United States. However, these faunas are dominantly preserved in dolostones with fossils preserved only as molds and casts, and fossils from dolostone facies have not been documented to the extent of Silurian crinoids in non-dolostone strata. Herein, an echinoderm fauna is described from the dolostones of the Cedarville Member of the Laurel Limestone (Wenlock, Homerian) from the Pepcon Quarry in west-central Ohio. The described fauna contains blastoids, hemicosmitoids, and crinoids, including Troosticrinus subcylindricus (Hall and Whitfield, 1875); Caryocrinites sp.; an unidentifiable diplobathrid camerate,  Periechocrinus tennesseensis (Hall and Whitfield, 1875); Periechocrinus egani? Miller, 1881; Stiptocrinus farringtoni (Slocom, 1908); Calliocrinus primibrachialis Busch, 1943; Calliocrinus popplemani n. sp.; Calliocrinus hadros n. sp.; and Lecanocrinus sp. Generic concepts for the Eucalyptocrinitidae are clarified; and, surprisingly, Eucalyptocrinites is absent from this fauna.

Methods
Fossil specimens were collected by the authors in the field. Specimens were cleaned, molds and casts were made of some.
