Book excerpt: Pterosaurs or flying reptiles were the first vertebrates to evolve flight. These distant relatives of modern reptiles and dinosaurs lived from the Late Triassic (over 200 million years ago) to the end of the Cretaceous (about 65 million years ago) a span of some 135 million years. When they became extinct, no relatives survived them and as a result these prehistoric animals cannot readily be compared with our modern-day fauna. So what do we know of these highly succsessful animals? The present summary answers this and many more questions based on the most recent results of modern scientific research. After a short introduction to palaeontology as a science and its history related to pterosaurs, it explains what pterosaurs were, when and where they lived, and what they looked like. Topics such as disease, injury and reproduction are also discussed. Separated from this text are 'Mark explains' boxes. Each of these explanations puts one specific species in the spotlight and focuses on its lifestyle. They show how diverse pterosaurs were, from small insectivorous animals with a wingspan of nearly 40 centimetres to the biggest flying animals ever to take to the air, with wingspans of over 10 metres and with a way of life comparable to modern-day storks. The text is illustrated with many full colour photographs and beautiful palaeo-art prepared by experts in the field.

Available in PDF, EPUB and Kindle. Book excerpt: First edition - This fully supports the literal Flood of Noah in the Bible, although the genre is nonfiction cryptozoology. For countless years, an old photograph has been seen on the internet, and some persons report they had seen it in a book decades before there was an internet. Now two scientists share their astonishing discovery: This is a genuine photograph of an actual animal that appears to have been a modern pterosaur, perhaps even a Pteranodon. Share in the excitement as one piece of evidence after another accumulates in favor of "Ptp" being a pre-1870 photograph of a modern pterosaur. Some evidences were independently discovered by two men (a physicist and a forensic videographer) who later shared their similar findings with each other, verifying the authenticity of Ptp. Was this photo created by a hoaxer who used Photoshop? See for yourself, as time and again the Photoshop conjecture is shot down. The missing-fingers of one of the soldiers in the photo is answered soundly, in a number of ways. The apparent "halo" near part of the head of another soldier-that is also answered. Not only did Photoshop have nothing to do with those details but there would have been no reason to use Photoshop in that way, if somebody wanted to create a hoax photo with some kind of model looking like a recently-deceased "pterodactyl." This is explained, in the book, by a videographer who has used Photoshop and knows how a hoaxer would and would not have used digital image-processing software. Don't confuse two photos that resemble each other. An imitation was created around the year 2000, apparently with Civil War reenactors, and that hoax-photo was made to look old, probably with software like Photoshop. It was then used in promoting a television show, but that IS NOT the photo examined in this book. Learn how others have been fooled by the similarity between those two photos. How much more credible is the Ptp photo! How could such an astonishing photograph have eluded scientific discovery for so long? That is also explained by the author, Jonathan Whitcomb, who has spent more time in the investigation of eyewitness reports of apparent extant pterosaurs than probably an other person in the world. Why did it take Whitcomb so many years to fully come to believe in the authenticity of Ptp? That is also explained, for this photograph has escaped the serious attention of almost everybody until January of 2017. Several introductory chapters include many sighting reports of large flying creatures, some of the accounts being published here for the first time. The descriptions of those apparent pterosaurs are compared with the apparent Pteranodon in Ptp. You'll learn why at least some of the sightings must have been encounters with actual extant pterosaurs. Above all, you'll learn why the animal shown in Ptp was a real pterosaur, probably shot by one or more of the soldiers shown in the photo.

Available in PDF, EPUB and Kindle. Book excerpt: The most authoritative illustrated book on flying reptiles available For 150 million years, the skies didn't belong to birds—they belonged to the pterosaurs. These flying reptiles, which include the pterodactyls, shared the world with the nonavian dinosaurs until their extinction 65 million years ago. Some pterosaurs, such as the giant azhdarchids, were the largest flying animals of all time, with wingspans exceeding thirty feet and standing heights comparable to modern giraffes. This richly illustrated book takes an unprecedented look at these astonishing creatures, presenting the latest findings on their anatomy, ecology, and extinction. Pterosaurs features some 200 stunning illustrations, including original paintings by Mark Witton and photos of rarely seen fossils. After decades of mystery, paleontologists have finally begun to understand how pterosaurs are related to other reptiles, how they functioned as living animals, and, despite dwarfing all other flying animals, how they managed to become airborne. Here you can explore the fossil evidence of pterosaur behavior and ecology, learn about the skeletal and soft-tissue anatomy of pterosaurs, and consider the newest theories about their cryptic origins. This one-of-a-kind book covers the discovery history, paleobiogeography, anatomy, and behaviors of more than 130 species of pterosaur, and also discusses their demise at the end of the Mesozoic. The most comprehensive book on pterosaurs ever published Features some 200 illustrations, including original paintings by the author Covers every known species and major group of pterosaurs Describes pterosaur anatomy, ecology, behaviors, diversity, and more Encourages further study with 500 references to primary pterosaur literature

This book was released on 2014-10-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fly above common true-life adventures, and dive into what may become the most unsettling scientific discovery since Copernicus and Galileo: living pterosaurs of the modern world--what a discovery! It soars above disputes about religion, revealing why an official discovery of an extraordinary animal has been delayed for so long. Above all, this explores human experience: eyewitnesses and those who interviewed them. People have become connected by common encounters; persons of various faiths, with various levels of education, from various countries and cultures, have seen a living pterosaur, commonly called "pterodactyl." Notwithstanding the delay in the official scientific discovery, eyewitnesses from around the world continue to encounter these flying creatures: featherless, long-tailed, often larger than any known bird. A few Americans explored a few islands in the southwest Pacific, in brief expeditions scattered between 1993 and 2007, looking for a modern pterosaur. "Creationist" each man was labeled, yet many of those following them, in recent years, carried no religious purpose. The creatures have many names: seklo-bali, duwas, wawanar, indava, kor, kundua. In Papua New Guinea, natives in isolated communities speak in village languages numbering in the hundreds, yet many natives carry a common fear in the dark: a huge glowing creature flying in the night. Natives on Umboi Island call it "ropen." Three American Christians--one middle-aged LDS-Mormon high priest and two younger Protestant Young Earth Creationists--explored parts of Umboi Island in two separate expeditions in 2004, interviewing native eyewitnesses of the elusive ropen. They returned home even more convinced that long-tailed pterosaurs live, even thrive, in Papua New Guinea. This resulted in the publication of several books, two scientific papers in a peer-reviewed journal, and over a thousand blog posts, written mostly by those who trudged the jungle trails of Umboi themselves and spoke with the eyewitnesses face to face. Those two expeditions in 2004 also cleared the path for other searches in Papua New Guinea and elsewhere, including expeditions led by those with no religious purpose in searching for ropens, namely the Destination Truth and Monsterquest television shows. This book illustrates how we succeed better by working with those of different faiths in pursuing a common goal, in this case finding a modern living pterosaur and supporting each other in our common beliefs and values. Why has the official scientific discovery been so long delayed? The causes are multiple and interrelated, but one obstacle has been resolved. Speculation that religious bias of investigators has played a big part in sighting reports of apparent pterosaurs--that conjecture has been shot down. Consider the words of Sandra Paradise, an eyewitness in Georgia: "The world is now totally different. I feel blessed that God has allowed me to see this creature that should not be here, and yet is, this strange dragon-like thing that lives somewhere in the woods . . ." Steven Cottingham, a government official in New Guinea many years ago, told the author, "My sighting occurred at night near Lab Lab on the southern tip of Umboi. The light lasted for four to five seconds, and until reading your reports now, have never been able to explain the sighting." The American flight instructor Duane Hodgkinson told the author about his encounter with a long-tailed flying creature in New Guinea: "It was a big one! I have a Piper Tri-Pacer airplane [wingspan twenty nine feet] and it appeared to be about that size." Patty Carson, of Southern California, said, "It did have a tail and it had a diamond shaped tip . . . The skin was a leathery, brownish reddish color. It had little teeth, a LOT of them."

This book was released on 2011-11-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Encounters with living pterosaurs Live "pterodactyls?" In the United States? Many scientists have long assumed all pterosaurs died millions of years ago. Now take a whirlwind tour of many years of investigations in cryptozoology, and prepare for a shock: At least two species of pterosaurs have survived, uncommon, not so much rare as widely, thinly distributed. Nocturnal pterosaurs have always lived among us, but hidden by something. Enter now the realm of a new branch of cryptozoology, a branch overshadowed by the dogma of a "universal extinction." How did scientists miss living pterosaurs? Get the answers here, hidden secrets about how these amazing flying creatures of the night have gone mostly unreported: Until recently, almost nobody would listen to eyewitnesses; but for the past seven years many of them have been interviewed by the author of this book. Many modern pterosaurs are much larger than any bat, many with long tails, many with head crests. What about news headlines? How did these creatures avoid media attention? Get the answers from years of work by American cryptozoologists. The old "fruit bat" explanation for reports of pterosaurs in Papua New Guinea--that bat idea has now been shot down; the tail length of the larger creatures has been estimated at a minimum of ten feet and a maximum of over twenty feet. More shocking, these giant long-tailed flying creatures are not confined to the southwest Pacific: They are seen in the contiguous United States of America. Most pterosaurs in North America, however, are smaller, with many wingspan estimates at less than fifteen feet; nevertheless, how shocking! What amazing encounters! In California, New Mexico, Texas, Arkansas, Florida, South Carolina, Pennsylvania, Ohio, and many other states, eyewitnesses have seen strange featherless creatures flying overhead. These are not bats; most have long tails and are bigger than any bat. Dive into eyewitness testimonies; compare sightings through the author's detailed analysis. Third edition, nonfiction

Available in PDF, EPUB and Kindle. Book excerpt: The most up-to-date and authoritative illustrated guide to the marvelous flying reptiles that dominated the skies of the Mesozoic for 160 million years Once seen by some as evolutionary dead-enders, pterosaurs were vigorous winged reptiles capable of thriving in an array of habitats and climates, including polar winters. The Princeton Field Guide to Pterosaurs transforms our understanding of these great Mesozoic archosaurs of the air. This incredible guide covers 115 pterosaur species and features stunning illustrations of pterosaurs ranging in size from swallows to small sailplanes, some with enormous, bizarre head crests and elongated beaks. It discusses the history of pterosaurs through 160 million years of the Mesozoic—including their anatomy, physiology, locomotion, reproduction, growth, and extinction—and even gives a taste of what it might be like to travel back to the Mesozoic. This one-of-a-kind guide also challenges the common image of big pterosaurs as ultralights that only soared, showing how these spectacular creatures could be powerful flappers as heavy as bears. Features detailed species accounts of 115 different kinds of pterosaurs, with the latest size and mass estimates Written and illustrated by the acclaimed researcher and artist who helped to redefine the anatomy and flight performance of pterosaurs Covers everything from pterosaur biology to the colorful history of pterosaur paleontology Includes dozens of original skeletal drawings and full-color life studies
Download or read book Evolution and Palaeobiology of Pterosaurs written by Eric Buffetaut and published by Geological Society of London. This book was released on 2003 with total page 358 pages. 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.
