Worthenia is an extinct genus of sea snail found in the fossil record. This genus is primarily found in rocks formed during the Devonian to Triassic periods (416-200 Ma) from the central areas of North America. Worthenia was named for the paleontologist Amos Henry Worthen, who lived from 1813 to 1888.[2]
Worthenia species have a "turban-shaped shell in which a raised ridge follows the margin of the whorls. Small nodes occur along the ridge, and the opening of the shell is oval and large."[3]
