Remontez le temps jusqu’à l’ère secondaire (– 252 à – 66 millions d’années) et plongez dans un monde aquatique où de spectaculaires reptiles incluant des prédateurs géants n’ont rien à envier à leurs contemporains terrestres, les dinosaures ! Ce livre vous fait découvrir l’univers de ces fascinants animaux, retournés à l’eau quelques millions d’années après que les premiers vertébrés en sont sortis, et leurs étonnantes modifications tant anatomiques que physiologiques et comportementales. Un voyage étourdissant, 20 000 lieues sous les mers et durant 180 millions d’années, à la rencontre des ichthyosaures, plésiosaures, mosasaures et bien d’autres ! Si aujourd’hui ne subsistent que quelques tortues et serpents marins, ce livre richement illustré vous permet de découvrir le passé glorieux des reptiles marins et leur extraordinaire diversité.

New material attributable to Deltasuchus motherali, a neosuchian from the Cenomanian of Texas, provides sampling across much of the ontogeny of this species. Detailed descriptions provide information about the paleobiology of this species, particularly with regards to how growth and development affected diet. Overall snout shape became progressively wider and more robust with age, suggesting that dietary shifts from juvenile to adult were not only a matter of size change, but of functional performance as well. These newly described elements provide additional characters upon which to base more robust phylogenetic analyses. The authors provide a revised diagnosis of this species, describing the new material and discussing incidents of apparent ontogenetic variation across the sampled population. The results of the ensuing phylogenetic analyses both situate Deltasuchus within an endemic clade of Appalachian crocodyliforms, separate and diagnosable from goniopholidids and pholidosaurs, herein referred to as Paluxysuchidae. This title is also available as Open Access on Cambridge Core.

Bijna overal ter wereld komen reptielen voor. Behalve op Antarctica, want daar is het te koud. Op de rest van de wereld hebben deze slimme dieren zich overal weten aan te passen, en hoe! Zo jaagt de Texaanse padhagedis in Noord-Amerika zijn vijanden weg met een bloedbom. De gouden stekelstaartgekko in Australië doet dat met zijn staart als stinkpistool! Mensen zijn al duizenden jaren gefascineerd door reptielen en in veel culturen spelen deze dieren een belangrijke rol. Zoals Yakumama, een reusachtige slang in de verhalen van de indianenstammen in Zuid-Amerika. En wat dacht je van de mysterieuze Chinese draken in Azië? Ga gauw mee op een spannende ontdekkingstocht en kom oog in oog te staan met de spectaculairste reptielen!

When it comes to study marine reptile ecology, the most efficient way to perform it is to study the most common fossil remains that are available. Those are the teeth. Massare’s triangle is certainly the first thing that comes to mind for anyone who has worked with marine reptile teeth. Her paper from 1987 was a milestone in marine reptile palaeontology and is still a reference nowadays. However, the method used to build the triangle includes a part of subjectivity that can be problematic and generate debates around the relevance of the different morphoguilds she established. A fully quantitative canvas for teeth shape analysis is proposed in this work. The objective is to develop a method based only on quantitative parameters and excluding qualitative and subjective ones. The method chosen to acquire the 3D data is the photogrammetry which gives precise 3D models that can be used to study shape variance with the help of computing power. Geometric morphometrics was used to quantify shape variations using GPA (Generalised Procrustes Analysis) and PCA (Principal Component Analysis). The results are displayed in morphospaces and are compared with Massare’s morphoguilds and some proposed by various authors that covered the subject of marine vertebrate dental morphologies.

This book accompanies Infectious Diseases and Pathology of Reptiles, Second Edition, to cover noninfectious diseases of reptiles, meeting the need for a similar, authoritative single-source reference. Subjects range from neoplasia, nutrition, and metabolic disease, and deposition disorders to developmental anomalies, trauma, and physical diseases, and the unique contribution of paleopathology and diseases of bone. Each chapter is supported by numerous figures, many of which are unique and cannot be found in the published literature. Readers will note that some of the chapters are based on organ system, a trend that will continue into the next edition to encompass all of the basic organ systems.

"Sea Turtle Research and Conservation: Lessons from Working in the Field is a comprehensive reference on sea turtle species as presented by global experts. The book looks at the challenges involved, such as cultural differences and how to conduct research in remote locations. Led by a renowned expert in sea turtle conservation, the book addresses the largest issues facing sea turtle species, including poaching, fishing snares, climate change, and more. Chapters in this book range from the use of cutting-edge technology to learn more about this elusive reptile, to working with communities with long histories of sea turtle trade and consumption. This book is an ideal resource for field biologists and marine conservationists, specifically those working in marine herpetology and with sea turtle species. Policymakers concerned with marine conservation, wildlife protection, and sustainable development will also find this a useful reference"--
