Trilobites of the Middle Ordovician Elnes Formation of the Oslo Region, Norway by Thomas Hansen Pdf

The highly fossiliferous upper Darriwilian to lower Sandbian Elnes Formation of Norway presents an interesting insight into the general responses and preferences of Lower Palaeozoic faunas belonging to a stable, mud dominated middle to outer shelf environment in connection with a major transgressive to regressive system tract. The rich trilobite fauna consisting of nearly 100 taxa is closely linked to the changes in the environment, being most abundant in a muddy and siliciclastic dominated environment just above storm wave base. The fauna is highly endemic for the region and the remainder of Baltoscania. This monograph presents a taxonomic description of the total trilobite fauna, including a new genus and seven hitherto unknown species. New and extensive biostratigraphical data is presented on the trilobites together with a study on the biogeographical and ecological aspects of the faunas.

Lower Ordovician trilobites of the Kirtonryggen Formation, Spitsbergen by Richard A. Fortey,David L. Bruton Pdf

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.

A Global Synthesis of the Ordovician System: Part 1 by D.A.T. Harper,B. Lefebvre,I. G. Percival,T. Servais Pdf

The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.
