Book excerpt: Book Excerpt: condition is not usual in amphibians or fishes. When hatched the young reptile is completely formed, the image of its parent, and has no need to grow a covering to its skin like some birds, or shed its tail like some tadpoles. The reptile is like the bird in freedom from important changes of form after the egg is hatched; and the only structure shed by both is the little horn upon the nose, with which the embryo breaks the shell and emerges a reptile or a bird, growing to maturity with small subsequent variations in the proportions of the body.[Illustration: FIG. 1 LUNG OF THE FISH CERATODUSPartly laid open to show its chambered structure (After Guenther)]THE REPTILE SKINBetween one class of animals and another the differences in the condition of the skin are more or less distinctive. In a few amphibians there are some bones in the skin on the under side of the body, though the skin is usually naked, and in frogs is said to transmit air to the blood, so as to exercise a respiraRead More

Book excerpt: The Ornithosauria is a brilliant work that explains the structures of the Pterodactyles of the Cambridge Greensand. They are small, extinct, flying reptiles of the late Jurassic and Cretaceous Periods, about the size of small to mid-sized birds. This is a well-written work compiled after years of thorough research. The writer used simple language to make the text more understandable and allow the general readers to grasp information quickly.

This book was released on 2013-06-12 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toothed pterosaurs are known from England since the 19th Century, through the works of James Scott Bowerbank (1797?1877) and Richard Owen (1804?1892). Harry Govier Seeley (1839-1909) soon realized that the English pterosaurs were distinct and referred several species in the genus Ornithocheirus. The fragmentary nature of the material, competing taxonomic proposals, synonymisations, and misunderstandings, lead to a very controversial taxonomic scenario. This monograph reviews thirty species that, at some point, were referred to Ornithocheirus. From these, fourteen are considered valid and belonging to five genera, three of them new. These genera are exclusive to the Cretaceous of England. Sixteen species are deemed undiagnosable. Descriptions and illustrations of all these species are provided. For the first time, a large number of species of the Ornithocheirus complex was included in a phylogenetic analysis and it is shown that most of them comprise a newly diagnosed clade, Anhangueria, with Brazilian and Chinese taxa.

Available in PDF, EPUB and Kindle. Book excerpt: Pterosaurs were a peculiar group of Mesozoic vertebrates, which acquired the ability to fly in an original way, using a membrane attached to a single finger of the hand. Ever since the first description of a pterosaur skeleton in 1784, these remarkable animals have elicited much discussion and controversy among palaeontologists, and many basic questions about their origin, evolution and biology remain disputed. In the last few years, interest in pterosaurs has been revived by numerous discoveries of new and sometimes remarkably preserved specimens, which have enlarged and changed our picture of this group. The volume begins with descriptions of several new pterosaurs from the Triassic, Jurassic and Cretaceous of Europe, North and South America, and Africa. Following this, alternative hypotheses of pterosaur phytogeny and evolution are put forward. Several papers discuss the functional anatomy of pterosaurs and its implications for aerial locomotion. The study of pterosaur footprints provides important new evidence concerning their terrestrial locomotion, and this approach is used in several contributions. A developing aspect of pterosaur research is bone histology, as shown by the final papers in this collection.
