Book Description
Mestognathus, an important Early Carboniferous conodont genus whose appearance has generally been thought to coincide with, and define, the base of the Visean, evolved from Clydagnathus during the Tournaisian and ranges from that stage into the Namurian. Five species, including M. harmalai sp. nov. and M. praebeckmanni sp. nov. , are distinguished by the gradual phyletic development of the parapet, the fixed blade, the anterior notch, the position of the carinal deflection, and the increasing tendency to evert the basal cavity. Mestognathus dhuensis and M. neddensis are demonstrated to be synonyms of M. beckmanni, M. bipluti, or Mestognathus spp.

Book Description
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.

Book Description
This multidisciplinary book focuses on the relationships and interactions between palaeobiogeography, biogeography, dispersal, vicariance, migrations and evolution of organisms in the SE Asia-Australasian region. The book investigates biogeographic links between SE Asia and Australasia which go back more than 500 million years. It also focuses on the links between geological evolution and biological migrations and evolution in the region. It was in the SE Asian region that Alfred Russell Wallace established his biogeographic line, now known as Wallace's Line, which was the beginning of biogeography. Wallace also independently developed his theory of evolution based on his work in this area.;The book brings together, for the first time, geologists, palaeontologists, zoologists, botanists, entomologists, evolutionary biologists and archaeologists, in the one volume, to relate the region's geological past to its present biological peculiarities. The book is organized into six sections. Section 1 Paleobiogeographic Background provides overviews of the geological and tectonic evolution of SE Asia-Australasia, and changing patterns of land and sea for the last 540 million years. Section 2 Palaeozoic and Mesozoic Geology and Biogeography discusses Palaeozoic and Mesozoic biogeography of conodonts, brachiopods, plants, dinosaurs and radiolarians and the recognition of ancient biogeographic boundaries or Wallace Lines in the region. Section 3 Wallace's Line focuses on the biogeographic boundary established by Wallace, including the history of its establishment, its significance to biogeography in general and its applicability in the context of modern biogeography.;Section 4 Plant biogeography and evolution includes discussion on primitive angiosperms, the diaspora of the southern rushes, and environmental, climatic and evolutionary implications of plants and palynomorphs in the region. The biogeography and migration of insects, butterflies, birds, rodents and other non-primate mammals is discussed in section 5, Non Primates. The final section 6 Primates focuses on the biogeographic radiation, migration and evolution of primates and includes papers on the occurrence and migration of early hominids and the requirements for human colonization of Australia.

Book Description
A compendium of papers first presented at the fifteenth annual International Congress on Carboniferous and Permian Stratigraphy, this book offers an overview of the latest research on rock formation that took place over 250 million years ago. This ancient sediment, which provides much of the mineral resources we use today, is a key indicator of massive environmental shifts that occurred around the creation of the super-continent Pangea. Organized thematically, the book covers a wide variety of topics, including the structural development of Carboniferous basins, the paleontology of those periods, and Carboniferous and Permian timescales and global correlations. As the contributors demonstrate, a better understanding of the evolution of the earth during the Carboniferous and Permian periods will not only help us find more mineral resources, but will also provide insight into important modern environmental questions.

Book Description
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.
