Rhineoderma wortheni
Taxonomy
Pleurotomaria wortheni was named by Hall (1856). It is a 3D body fossil. Its type locality is Hunter Valley Quarries, 3 miles northwest of Bloomington, which is in a Meramecian carbonate limestone in the Salem Formation of Indiana.
It was recombined as Phanerotrema wortheni by Buddington and Chapin (1929); it was recombined as Rhineoderma wortheni by Knight and Bridge (1944), Rollins (1975) and Wagner (2023).

Diagnosis

|---|---|---|
| J. Hall 1856 (Pleurotomaria humilis) | Shell depressed, trochiform, oblique, spire little elevated, consisting of three or four volutions which increase rapidly in size from the apex; volutions depressed-convex above, and declining to the periphery; base of the last volution less convex than on the upper side, sub-obtusely angular on the periphery which is marked by a narrow groove, little wider than the usual spaces between the revolving striae; surface marked by revolving and transverse stri2 which are stronger and more distant on the upper side of the volution, giving it a beautiful cancellated appearance; while they are closer and finer on the lower side of the shell; mouth transversely oval; umbilicus small. | |
| J. Hall 1856 | Shell depressed sub-globose; spire but little elevated, oblique from the great expansion of the last volution; volutions about three, somewhat flattened above, rapidly expanding, so that the last volution makes nearly the whole bulk of the shell; obtusely angulate on the periphery; upper margin of the volutions marked by a row of strona nodes, which extend albout one-third across; surface marked above by striae parallel to the lines of growth which on the last volution disappear in passing over the angulate periphery; base of last volution marked by strong revolving lines on the space between the outer margin and the umbilical area; base -deeply excavated about the umbilical region, but the umbilicus is unknown. Aperture sub-quadrate, upper edge of the outer lip projecting far over the lower. Diameter .60; height .48 of an inch. |
