Deseret Limestone : ウィキペディア英語版 | Deseret Limestone
The Deseret Limestone, also known as the Pine Canyon Formation, is a geologic formation in Utah. It preserves marine fossils dating back to the Carboniferous period or Mississippian age. It was formed by the Panthalassa ocean around 340 Ma. Fossils are mostly of tabulate and rugose corals, and other marine invertebrates; vertebrates are represented by conodonts. The Deseret is a 500-foot thick layer of dolomitic limestone with chert, with a basal layer of black shale that is host rock for many Utah caves such as Timpanogos Cave National Monument.〔(【引用サイトリンク】author=Various Contributors to the Paleobiology Database )〕 ==See also==
