Book Synopsis Mid-Cambrian Trilobites from the Lowest Part of the Cow Head Group, Western Newfoundland by : Graham A. Young
Download or read book Mid-Cambrian Trilobites from the Lowest Part of the Cow Head Group, Western Newfoundland written by Graham A. Young and published by Geological Survey of Canada. This book was released on 1989 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rich mid-Cambrian trilobite faunas were recovered from limestone boulders in conglomerates that form the lowest exposures of the Cow Head Group (Shallow Bay Formation) near Broom Point in western Newfoundland. These boulders were derived from various shelf-edge and upper slope environments along the margin of Laurentia. Twenty-nine species representing twenty genera are described. Three trilobite biofacies are defined based on the abundance of the genera in separate boulders."

Book Synopsis Middle and Upper Cambrian Acritarch and Trilobite Zonation at Manuels River and Random Island, Eastern Newfoundland by : F. Martin
Download or read book Middle and Upper Cambrian Acritarch and Trilobite Zonation at Manuels River and Random Island, Eastern Newfoundland written by F. Martin and published by Geological Survey of Canada. This book was released on 1988 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed descriptions of acritarchs and trilobites found in the Cambrian strata of the Avalon Peninsula of eastern Newfoundland. A biostratigraphic zonation based on acritarchs is proposed, and an analysis of 7 previously described microfloras is refined and completed, enabling a more accurate correlation to be made with trilobite-bearing strata in Great Britain and Scandinavia, and with acritarch faunas in northern Norway, the Baltic area and the Gondwanaland region.

Book Synopsis Ontogeny, Intraspecific Variation, and Systematics of the Late Cambrian Trilobite Dikelocephalus by : Nigel C. Hughes
Download or read book Ontogeny, Intraspecific Variation, and Systematics of the Late Cambrian Trilobite Dikelocephalus written by Nigel C. Hughes and published by . This book was released on 1994 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biometric analyses of well-localized specimens of the trilobite Dikelocephalus from the St. Lawrence Formation (Upper Cambrian), northern Mississippi Valley, suggest that all specimens belong to a single, highly variable morphospecies, D. minnesotensis. A complex pattern of ontogenetically-related and ontogeny-independent variation produced a mosaic of morphotypes, which show greater diversity than previously recorded within trilobite species. There is considerable variation within collections made from single beds. Variations of characters among collections are mosaic, and are clinal in some cases. Patterns of variation within Dikelocephalus cannot be related to lithofacies occurrence. There are no obvious temporal variations in D. minnesotensis within the St. Lawrence Formation, but some Dikelocephalus from the underlying Tunnel City Group may belong to a different taxon. The validity of this early taxon is questionable due to a lack of available material. The mosaic pattern of variation in Dikelocephalus mimics that documented at higher taxonomic levels in primitive libristomate trilobites, and helps explain difficulties in providing a workable taxonomy of primitive trilobites. Results caution proposition of evolutionary scenarios that do not take account of intraspecific variation. The recovery of dorsal shields of Dikelocephalus permits the first detailed reconstruction of the entire exoskeleton. The systematics of the genus is revised and twenty-five species are suppressed as junior synonyms of D. minnesotensis.
