| contents | The Early to Middle Ordovician graptolite faunal succession of the Trail Creek region, central Idaho, U.S.A. J. Maletz D. Goldman M. Cone Ciencias de la Tierra Arenig Ordovician Graptolites North America Biostratigraphy The Middle Ordovician graptolite biostratigraphy of the Trail Creek region of Idaho is reviewed and revised.The oldest known fauna belongs to the Didymograptellus bifidus Biozone. The Isograptus victoriae lunatus, I.victoriae maximodivergens, Oncograptus, Undulograptus austrodentatus and Holmograptus lentus Biozonescan be differentiated. Pseudophyllograptus archaios (Braithwaite) is found for the first time in the Trail Creekregion. This species represents a conspicuous North American mid-continent faunal element and enables thecorrelation of the endemic P. archaios-C. flexilis Biozone of Utah with the D. bifidus Biozone of the Pacificfaunal realm, thus, providing an important tool for the correlation of endemic mid-continent faunas with thepandemic deep water graptolite faunas. 2005 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50530408 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.4 Vol.3 |
