Abstract

Specimens of the worm tube Coleolus curvatus Kindle are reported from the upper part of the Cleveland Shale Member of the Ohio Shale in northern Ohio, where they are part of a diverse invertebrate assemblage. These tubes superficially resemble Styliolina, but they are larger and are curved rather than straight; in this curvature, they also superficially resemble scaphopods. For comparison, specimens of Coleolus aciculatum Hall from the Gowanda Shale of New York are illustrated. The ranges of both species are extended from Middle Devonian to Late Devonian and neither occurrence has been previously reported for the genus. Coleolus may have lived partially buried in the mud with its aperture a few millimeters above the bottom.
