The taxonomy is modernized and updated for Jurassic planktonic foraminifera using all available literature and stratigraphic series of sediment samples from Canada, Portugal, France, Switzerland, Poland, Lithuania, Russia and Dagestan. The regional stratigraphy of all sampled sections is outlined. Many of the 65– µm sample residues yielded well-preserved free specimens, with local Cited by: 9. Diversity increased through the Lower Jurassic to a level which remained more or less stable from Middle Jurassic times onwards, while the origination rate shows the opposite trend. Extinction rate increased early in the period to a maximum in the Pliensbachian and fell thereafter to a low value until the Tithonian, which is marked by a sharp by:
New thoracican cirripede material from the Kimmeridge Clay (Upper Jurassic, Tithonian) is described.

Post-Paleozoic crinoids exploited a wide range of ecological strategies despite being stereotyped in many aspects of form.
This difference between the radiations is consistent with an increase in the rigidity of genetic and developmental systems. The range of post-Paleozoic designs is not in essence a subset of the Paleozoic by: British Lower Jurassic strata have long been famed for its wealth of fossils, both vertebrate and invertebrate.
Many species were first described from sites described in this volume, and these. Crinoid systematics, phylogeny and palaeobiology. Includes a monograph on Lower Jurassic crinoids, several chapters in the best-selling Fossil Crinoids book, and a ground-breaking reinterpretation Title: Geology Curator at National.
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Describes 45 sites, from small quarries to magnificent coastal cliffs, which represent the entire British outcrop, from North-East Scotland to South Wales and South-West England.
This book demonstrates the diversity of Lower Jurassic stratigraphy and facies in Britain. It is of considerable importance within a British and Western European context. 1 British Lower Jurassic stratigraphy: an introduction 1 Introduction M.J.

The Jurassic Coast, as this region is known, stretches for almost miles and encompasses million years of earth’s history. At the far west end, in Exmouth, the cliffs date to the Middle Author: Sarah Zielinski.
