Carpocrinus (Echinodermata: Crinoidea) from the Late Silurian of Somerset Island, Northwest Territories, Canada
Carpocrinus arcticus n. sp. is the first Silurian crinoid to be reported from Arctic Canada (Read Bay Formation, Somerset Island). The species is distinguished from other North American Carpocrinus by its nonlobate calyx, plates with impressed sutures, and granular plate ornamentation. It is a membe...
