This update isdesigned to give, in outline form, an account of the nature of the skeletal system of numerous reptile types both living and extinct.

Book Description
The 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.

Book Description
This volume brings together state-of-the-art reviews of the non-biostratigraphic and biostratigraphic data that are used to define and correlate Permian time intervals. It includes analyses of Permian radio-isotopic ages, magnetostratigraphy, isotope-based stratigraphy and timescale-relevant biostratigraphy. It is the first book devoted to this subject and represents the cutting edge of Permian time-scale research.

Book Description
An introduction to the evolution and adaptation of amphibians and reptiles, bridging the gulf between the plethora of 'popular' books and the more advanced texts directed towards the needs of specialist research workers, thus making it accessible to advanced students worldwide. It explains basic principles in non-technical terms, and covers the adaptive responses to natural selection which have engendered the diversity of forms that exist in the fossil record and are found in the world today. The book also includes the extinct forms such as dinosaurs, ichthyosaurs and plesiosaurs, and concludes with a dsicussion of relationships with mankind and the preservation of diversity. XXXXXXX Neuer Text This title is an introduction to the evolution and adaptation of amphibians and reptiles, which is accessible to a wide range of readers.

Book Description
The PhyloCode is a set of principles, rules, and recommendations governing phylogenetic nomenclature, a system for naming taxa by explicit reference to phylogeny. In contrast, the current botanical, zoological, and bacteriological codes define taxa by reference to taxonomic ranks (e.g., family, genus) and types. This code will govern the names of clades; species names will still be governed by traditional codes. The PhyloCode is designed so that it can be used concurrently with the rank-based codes. It is not meant to replace existing names but to provide an alternative system for governing the application of both existing and newly proposed names. Key Features Provides clear regulations for naming clades Based on expressly phylogenetic principles Complements existing codes of nomenclature Eliminates the reliance on taxonomic ranks in favor of phylogenetic relationships Related Titles: Rieppel, O.
