Morphology and Evolution of Turtles
Author: Donald B. Brinkman
Publisher: Springer Science & Business Media
ISBN: 9400743092
Category : Science
Languages : en
Pages : 577
Book Description
This volume celebrates the contributions of Dr. Eugene Gaffney to the study of turtles, through a diverse and complementary collection of papers that showcases the latest research on one of the most intriguing groups of reptiles. A mix of focused and review papers deals with numerous aspects of the evolutionary history of turtles, including embryonic development, origins, early diversification, phylogenetic relationships, and biogeography. Moreover it includes reports on important but poorly understood fossil turtle assemblages, provides historical perspectives on turtle research, and documents disease and variation in turtles. With its broad scope, which includes descriptions of material and new taxa from Australia, Asia, and Europe, as well as North and South America, this work will be an essential resource for anyone interested in the morphology and evolution of turtles. “This volume’s breadth of time, geography, and taxonomic coverage makes it a major contribution to the field and a ‘must have’ for all vertebrate paleontologists.”, James F. Parham, California State University, CA, USA “A comprehensive and sweeping overview of turtle evolution by the top experts in the field that will interest everyone curious about these unique reptiles.” Jason S. Anderson, University of Calgary, Canada “An invaluable addition to the literature that covers the full spectrum of approaches toward understanding the evolution of these noble creatures.” Ann C. Burke, Wesleyan University, CT , USA “A truly comprehensive volume that both the student of fossil turtles, as well as the general reader interested in these enigmatic creatures, will find fascinating.” Tyler Lyson, Yale University, CT, USA

Turtles as Hopeful Monsters
Author: Olivier Rieppel
Publisher: Indiana University Press
ISBN: 0253025079
Category : Science
Languages : en
Pages : 216
Book Description
Where do turtles hail from? Why and how did they acquire shells? These questions have spurred heated debate and intense research for more than two hundred years. Brilliantly weaving evidence from the latest paleontological discoveries with an accessible, incisive look at different theories of biological evolution and their proponents, Turtles as Hopeful Monsters tells the fascinating evolutionary story of the shelled reptiles. Paleontologist Olivier Rieppel traces the evolution of turtles from over 220 million years ago, examining closely the relationship of turtles to other reptiles and charting the development of the shell. Turtle issues fuel a debate between proponents of gradual evolutionary change and authors favoring change through bursts and leaps of macromutation. The first book-length popular history of its type, this indispensable resource is an engaging read for all those fascinated by this ubiquitous and uniquely shaped reptile.

The Phylogenetic Relationships of Soft-shelled Turtles (family Trionychidae)
Author: Peter Andre Meylan
Publisher:
ISBN:
Category : Reptiles
Languages : en
Pages : 101
Book Description
Phylogenetic analysis of nearly one hundred characters of the osteology of trionychid turtles provides abundant data on the phyletic relationships of this family to other turtles and on the interrelationships of its members. These data suggest that the family Trionychidae shares a unique common ancestor with the Dermatemydidae, Kinosternidae and Carettochelyidae , and that the Kinosternidae shares a unique common ancestor with the Trionychidae and Carettochelyidae. Furthermore, it is the staurotypine kinosternids that are most closely related to the Trionychidae and Carettochelyidae. Carettochelyids and trionychids share numerous unique features and constitute a monophyletic group . Within the Trionychidae, the subfamilies Cyclanorbinae and Trionychinae are recognized as monophyletic clades. Recognition of three cyclanorbine genera, Cycloderma , Cyclanorbis and Lissemys , is warranted. Within the Trionychinae, four distinct clades are recognized. The Trionyx cartilaglneus group includes Chitra indica and Pelochelys bibroni on the basis of the unique location of the foramen posterior canalis carotici interni, and features of the trigeminal region. The North American group, which includes T. triunguis , T. euphraticus , T. swinhoei , T. ferox , T. spiniferus and T. muticus, can be recognized by the presence of eight or fewer neurals (first and second are fused), deeply emarginate prefrontals and a large contribution by the parietal to the processus trochlearis oticum. The Indian group includes four species: T. gangeticus , T. hurum , T. leithii and T. nigricans . All exhibit a free first neural, five plastral callosities and intermediately extended epiplastra. Lastly, the T. steindachneri group is diagnosed by a descending spine of the opisthotic which divides the fenestra postotica in most specimens. Two equally parsimonious arrangements of the Trionychinae differ in the placement of the North American clade. In one, this clade is the sister group of the T. cartilagineus clade; in the other it is the sister group of the T. steindachneri clade. In both, the Indian group is paraphyletic and gives rise to the T. steindachneri clade. A tentative revision of the classification of the family Trionychidae is provided. In it, five generic names currently in the synonymy of Trionyx are resurrected to denote unique clades of trionychine turtles.

The Phylogenetic Relationships of Soft-shelled Turtles (family Trionychidae)
Evolutionary Relationships of Marine Turtles: a Molecular Phylogeny Based on Nuclear and Mitochondrial Genes
Origin, Evolution and Biogeographic History of South American Turtles
Author: Marcelo S. de la Fuente
Publisher: Springer Science & Business Media
ISBN: 3319005189
Category : Science
Languages : en
Pages : 177
Book Description
The extended continental South American turtle record (Norian to Lujanian) allows us to follow the evolution of this reptile clade from its origins. Several significant stem turtle taxa such as: Palaeochersis talampayensis and Condorchelys antiqua provide information on the first steps of turtle evolution. Others such as: Chubutemys copelloi or Patagoniaemys gasparinae provide clues to the origin of the bizarre horned tortoises of the clade Meiolaniidae. The panpleurodiran species such as Notoemys laticentralis or Notoemys zapatocaensis shed light on the origin of modern pleurodiran turtles. This book explores aquatic and terrestrial cryptodiran turtles, South Gondwana pleurodiran turtles, North Gondwana pleurodiran turtles; Meiolaniforms and early differentiation of Mesozoic turtles.
