Halysites sp. - fossil coral in dolostone from the Silurian of Ohio, USA. (public display, Geology Department, Wittenberg University, Springfield, Ohio, USA) Halysitids are a group of extinct, colonial corals. They are readily identifiable - their corallites are linked end-to-end in a distinctive pattern resembling chains (hence the common name “chain corals”). Halysitids are one of the several families of Paleozoic tabulate corals. They were an important reef-building component in the Silurian throughout the world. They occur in shallow-water marine carbonate facies. Classification: Animalia, Cnidaria, Anthozoa, Tabulata, Halysitidae Stratigraphy: Lockport Dolomite, Niagaran Series, Middle Silurian Locality: Rockford Stone Company Quarry (now abandoned & flooded), 1.5 miles northwest of the town of Rockford, northern Mercer County, northwestern Ohio, USA. (40° 42' 29.10" North latitude, 84° 40' 01.28" West longitude) |
