Fossil associations in the High Tor Limestone (Lower Carboniferous) of South Wales

North. Ariz. Univ., Dep. Geol., Flaggstaff, AZ, United States

Invertebrate marine fossils from 44 localities within the High Tor Limestone in South Wales occur mainly in distinct molluscan or coral-brachiopod associations. Cluster analysis of the species based upon their mutual occurrence and abundance indicates that three recurring fossil associations (probable communities) are represented; 1, a bellerophontid association characterized by gastropods, bivalves and nautiloids in a lime wackestone; 2, a caninioid association including solitary and colonial corals, productid and large chonetid brachiopods commonly in a lime grainstone; and 3, a Rhipdomella association characterized by orthid and small chonetid brachiopods, solitary rugose corals and bryozoans in a lime packstone.--Modified journal abstract.
