Systematics and biostratigraphy of Lower Cambrian trilobites of western Laurentia

Bohach, Lisa Lynn 20 July 2018 (has links)
Medial Lower Cambrian strata from continental shelf deposits of western Laurentia yield abundant, low diversity trilobite faunas. New faunas from the Cranbrook and Eager formations (southeastern British Columbia) and the upper Campito, Poleta, Harkless and Saline Valley formations (southwestern Great Basin, California and Nevada) have yielded: 33 species of Olenellina (20 new); 2 new species of Edelsteinaspidae (Redlichiina); 13 species of Corynexochida (5 new); 4 species of Ptychopariina (1 new); 1 new species of Eodiscina; 1 species of Oryctocephalidae; 1 new species of Protypidae; and 1 possible species of Cheiruroideidae. One new genus, Wannerellus, is established and tentatively assigned to the Wanneriidae. Systematic studies emphasize the importance of early ontogenetic features and ventral morphology in determining supraspecific relationships. Major changes are made to the suprageneric classification of the Olenelloidea: the Wanneriidae is recognized as a family separate from the Olenellidae; the Laudoniinae and Gabriellinae are abandoned and their type genera assigned to the Wanneriidae; the Mesonacinae is characterized as a peramorphic subfamily of the Olenellidae; and the Bristoliinae is synonymized with the Biceratopsinae (Olenellidae). The Corynexochidae is also changed in membership to include the Dorypyginae (=Ogygopsidae). Heterochrony is a major pattern of evolutionary change in Lower Cambrian trilobites. Biostratigraphic division of the medial lower Cambrian comprises 10 new subzones of 4 zones and is the first species-based trilobite zonation for Laurentia. It replaces previous genus-based zonations that are imprecise and questionable in recognition. In ascending order, the zonation includes: the Nevadia weeksi and Nevadia palmeri subzones of the Nevadia Zone; the Nevadella parvoconica and Nevadella eiicharis subzones of the Nevadella Zone; the Elliptocephala stewarti, Gabriellus poletensis and Wannerellus alcatrazensis subzones of the Elliptocephala Zone; and the Wanneria logani, Wanneria dunnae and Proliostracus buelnaensis subzones of the Olenellus transitans Zone. These zones and subzones can be correlated with other successions in western and eastern Laurentia. Biofacies differentiation of restricted shelf deposits is poorly developed in the Nevadella though Elliptocephala Zones. For this interval, the Nevadella and Wanneriid biofacies are successive biofacies of restricted shelf deposits and the Labradoria and Ekwipagetia biofacies are successive biofacies of open shelf deposits. Biofacies differentiation is well developed in the Olenellus transitans Zone, with an Olenellus Biofacies in elastics; a Wanneriid Biofacies in silty and oolitic carbonates; a Bonnia Biofacies in pure carbonates; and an Ogygopsis Biofacies in open shelf deposits. / Graduate

Late Quaternary glaciation and environmental change in Southern Ross-shire, Scotland

Tate, C. Jill January 1996 (has links)
Despite considerable active research in the realm of Quaternary studies in Scotland, some parts of the Scottish Highlands remain largely uninvestigated in terms of both glacial and environmental history. For many areas of Scotland the glacial history has been examined: researchers have ascertained aspects of the nature of the Late Devensian (Weichselian) ice sheet that covered most of Scotland and subsequent readvances, chiefly the Loch Lomond Readvance. In a 1979 review of the Loch Lomond Readvance in the British Isles, Sissons published a map of the glacial limits relating to this latest period of glacial activity in Scotland (Figure 1.1). Since then this map has been only slightly modified with certain limits having been established in the western Grampians. For the area further north, little accurate information has been added to this picture. One of the most noticeable omissions in relation to the Loch Lomond Readvance is in the area between Glen Carron and Glen Shiel in southern Ross-shire. Published research regarding the earlier Late Devensian ice sheet is also sparse. Information regarding other aspects of the Quaternary such as those detailed in other parts of the Scottish Highlands are similarly lacking for this area. There are no published accounts of the vegetation history of the area nor of Late Quaternary sea-level changes. This study seeks to fill in some of these gaps with specific reference to the Late Devensian glaciation and aims to relate the patterns of glaciation with other contemporaneous environmental changes through to the establishing of interglacial conditions in the early Flandrian period. Recent studies have demonstrated that aspects of the Late Quaternary environment can usefully be related and this study attempts to follow a similar procedure.
