The shallow-shelf carbonates of the Lower Border group and equivalent strata of the Northumberland trough have yielded conodont elements belonging to 28 multielement species. Study of these cavusgnathid-dominated faunas highlights the need for major revision of the Cavusgnathidae. Cloghergnatus globenskii Austin is an ecophenotype of Taphrognathus varians Branson and Mehl; Cloghergnathus Austin is ajunior synonym of Taphrognathus Branson and Mehl, Capricornognathus Austin appears to be a junior synonym of Patrognathus Rhodes, Austin, and Druce. The appartuses of Cavusgnathus hudsoni (Metcalfe), Taphrognathus varians, Polygnathus mehli Thompson, and Apatognathus cuspidatus Varker are described for the first time. Patrognathus capricornis (Druce), Mestognathus beckmanni Bischoff, Polygnathus bischoffi Rhodes, Austin, and Druce, and "Apatognathus" sp. a are partially reconstructed. The assignment of C. hudsoni to Cavusgnathus extends the range of the genus into the Tournaisian Series in Britain.

The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.

Silurian trilobites are described from two contrasting facies in the northern Yukon Territory: basinal sediments of the Road River Formation at Prongs Creek and shallow-water limestones of the Illtyd Range. An Otarion Association from dark grey, argillaceous lime mudstones (Lower Silurian) consists of Kosovopeltis, Otarion (Songkania), Cromus, and Leonaspis. These trilobites are identical to those described by Pousen (1934) from his Cape Schuchert Formation of North Greenland. A Stenopareia Association from off-white biosparites (Lower Silurian) includes Stenopareia, a bumastine, Kosovopeltis, and Scotoharpes. A Hedstroemia Association occurs in an Upper Silurian debris flow. It includes Hedstoemia, Prantlia, Balizoma, and Paracybantyx. An incomplete ontogeny of Kosovopeltis borealis (Poulsen) comprises a protaspis and four different transitory pygidia. The bumastine genus Paracybantyx is new. New species are Paracybantyx asulcatus, Stenopareia illtyd, Hedstroemia kutchini, H. sourdoughi, and Prantlia vagrans.

Rocks of Lower Carboniferous age are widely developed across Europe. Apart from their instrinsic geological interest they are hosts to major Zn-Pb-Cu-Ba deposits in Ireland and Au-FeS2 deposits in the Iberian Pyrite Belt. Further, the Upper Palaeozoic rocks of Europe are increasingly becoming the target of oil and gas exploration. The wealth of data on Lower Carboniferous rocks,while not guaranteeing success, will be an invaluable tool for exploration. This book brings together in one volume advances over the last decade in several specialist subdisciplines of geology. It contains papers on carbonate and clastic sedimentology, palaeontology, palaeoecology, stratigraphy and biostratigraphy.
