This book was released on 2013-10-22 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes early Ordovician (Ibexian: Tremadocian–early Floian) trilobites from Northern Spitsbergen from the section through the Kirtonryggen Formation adjacent to Hinlopen Strait. The Formation is divided into three Members, each with distinct trilobites collectively representing the fullest known succession from the Bathyurid biofacies of the eastern Laurentian carbonate platform. Previous research on the Ordovician of Spitsbergen is summarised and correlations with similar faunas previously described from Canada, Greenland, western Newfoundland, Vermont–New York State, Oklahoma and Missouri are discussed. Taxonomic problems are discussed in detail leading to the recognition of 53 species, of which 15 are new, belonging to 31 genera including four new. Twenty-four taxa are described under open or tentative nomenclature. The lower Member yields the earliest known occurrences of the Illaenoidea, Proetoidea and Scutelluoidea, supporting the hypotheses relating the origin of new major clades to inshore habitats.

Download or read book Trilobites from the Survey Peak Outram and Skoki Formations Upper Cambrian Lower Ordovician at Wilcox Pass Jasper National Park Alberta written by William Thornton Dean and published by . This book was released on 1989 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The trilobites from the Upper Cambrian to Lower Ordovician Survey Peak, Outram and Skoki formations at Wilcox Pass, Alberta, comprehensively described in this report, belong to 48 genera. One new genus and six new species are described, and type material for seventeen previously described species from corresponding strata elsewhere in the Rockies is redescribed or re-illustrated. This report establishes a biostratigraphic framework for the Wilcox Pass sequence, from the highest part of the Upper Cambrian Trempealeau Series through the entire Lower Ordovician, based on trilobite zones.

Available in PDF, EPUB and Kindle. Book excerpt: This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long history.
