Available in PDF, EPUB and Kindle. Book excerpt: "Conodonts were discovered in the limestones of the Marathon region in the Big Bend country, Brewster County, Texas, as a result of field work during the summer of 1939. This was not the first known occurrence of these fossils from this region, however, as King earlier mentioned the occurrence of conodonts in siliceous shales of Devonian age. The discovery of conodonts in the Ordovician and Pennsylvanian limestones of the area had its inception in the attempt to determine whether the Dimple limestone (lower Pennsylvanian) or Maravillas limestone (upper Ordovician) was involved in a fault that was being mapped. These limestones are similar lithologically and the nature of the outcrop along the fault trace was such that the age relations of the limestone involved could not be determined...The stratigraphic distribution, systematic descriptions, and illustrations of conodonts of Ordovician and Pennsylvanian age from the Marathon region form the basis of this thesis. In some instances, such as the occurrence in the dimple formation, conodonts are the only positively identifiable fossils found in the rocks and, for this reason, have special significance in determining the age of these beds. The Ordovician conodont faunas are of importance because the occurrence in this region extends their known geographic and geologic range"--Introduction, pages [1]-3.

Download or read book Taxonomy, Evolution and Biostratigraphy of Conodonts from the Kechika Formation, Skoki Formation, and Road River Group (Upper Cambrian to Lower Silurian), Northeastern British Columbia written by Leanne J. Pyle and published by NRC Research Press. This book was released on 2002 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conodonts, the tiny, phosphatic, tooth-like remains of an extinct group of early vertebrates, are the most important fossil group for biostratigraphy throughout their stratigraphic range from Late Cambrian to Late Triassic. This monograph represents a benchmark study of these important zonal fossils. The detailed paleontological work not only provides a taxonomic basis for future studies on early Paleozoic conodonts but also focuses on the evolution of conodonts in the early Ordovician, a time of extraordinary adaptive radiation. The taxonomic work provides detailed descriptions and illustrations of 185 species representing 69 genera. Seven new genera and 39 new species are described. The high diversity of taxa across the platform-to-basin transect shows the biogeographic differentiation and spatial ecological partitioning of conodonts through time. The taxonomy permits the refinement to the biostratigraphic zonation within two faunal realms for British Columbia that can be correlated with schemes elsewhere in North America and also internationally.

Download or read book Darriwilian to Katian (Ordovician) Graptolites from Northwest China written by Yuandong Zhang and published by Elsevier. This book was released on 2016-11-29 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darriwilian to Sandbian (Ordovician) Graptolites from Northwest China analyzes the significance of these exquisite, mostly pyritic, graptolites of the middle to late Ordovician period from North China and Tarim, China—locations that have developed the world’s most complete successions of strata and fossil records. The book provides the first systematic account of the renowned graptolite faunas, with over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone, also presenting a comprehensive accounting of the graptolites during the critical transition from the middle to late Ordovician period with important data on new morphologies, the latest conventions in classification, diversity change and evolution, refined biostratigraphy divisions, and correlation with other major regions or continents. The book provides a key resource for paleontologists, stratigraphic specialists, petroleum geologists, and graduate students in varying fields of geology. Presents the first systematic accounting of these world-renowned graptolite fauna Provides an ideal reference for those interested in rocks, fossils, and biostratigraphy Presents over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone Includes research from the top, most influential, Ordovician graptolite and conodont paleontologists in the world Generously illustrated with four-color figures and photos throughout
