Paleoecological interpretation of the Salina (Upper Silurian) section in New York state, based on lithologies and faunas, indicates a shallow aquatic environment with highly variable salinity. The Syracuse formation, which includes the major evaporite beds of the region, contains undescribed ostracodes, a trilobite (Calymene sp.), 2 species of Ceratiocaris (Ceratiocaris sp. and C. nolli n. sp.), and eurypterids assignable to 5 genera. Eurypterus remipes flintstonensis Swartz, Erieopterus sp., and specifically undeterminable Pterygotus fragments occur in the upper Syracuse. Pterygotus fragments have also been found near the bottom of the formation. Waeringopterus cumberlandicus n. gen., n. subsp., is restricted to the lowest member of the Syracuse formation. A single fragment of Carcinosoma has been found in the Camarotoechia zone, near the middle of the formation.
