Many fossils of shelly organisms (e.g., bivalves, gastropods, brachiopods, cephalopods) have had the original hard parts dissolved away. In such cases, the fossil itself is an impression of the outside of the shell (external mold) or an impression of the inside of the shell (internal mold). Sthenarocalymene celebra (Arthropoda, Trilobita, Polymerida, Calymenidae) - this fossil calymenid trilobite specimen is a nice example of dissolution. The trilobite is preserved as an internal mold in Silurian dolostone from southwestern Ohio, USA. Most trilobites found in dolostones are similarly preserved. This trilobite is Sthenarocalymene celebra (Raymond, 1916). Over the years, trilobitologists haven’t agreed on the proper generic assignment for celebra. The species has been variously assigned to the genera Calymene, Gravicalymene, Flexicalymene, and Sthenarocalymene.Stratigraphy: Cedarville Dolomite, upper Lockport Group, upper Niagaran Series (= upper Wenlockian Series), upper Middle Silurian |
