Dinosaur Poster Set Of 4, Laminated

Fischer Technical DINOPOS-SET, Dinosaur Poster Set Of 4, Laminated

Description

This set includes four laminated posters. All posters are 24" x 36". Titles includes are: Dinosaur Evolution, Tyrannosaurus, Sauropods, and Pterosaurs. A301 - Dinosaur Evolution Paleontologists have long been aware of the hereditary relationships between species and realized that categorizing them into neat little compartments was inadequate for their purposes. They discarded the Linnaean system and replaced it with phylogenetic systematics, also known as cladistics. This new system organizes species and groups in relationship to one another, based on the development of physical characteristics. This poster represents the first time that this new system was ever used to create a pictorial cladogram showing how dinosaurs evolved over millions of years. A303 Tyrannosaurs This is an exciting presentation of an extremely popular subject. The central design consists of magnificently detailed illustrations of all nine members of the tyrannosaur family, all in scale to one another. Of course T. rex takes center stage, but note the size of some of the others. Above them, insets explore anatomy and ancestors. The latest discoveries are also shown: the newly found feathered tyrannosaur, and the remarkable growth rate recently proven by researchers. Other insets explore social habits and provide a list of all North American museums where tyrannosaur fossil skeletons are on display. A312 Sauropods Sauropoda are a clade of saurischian (“lizardhipped”) dinosaurs. Sauropods were herbivorous (plant-eating), long-necked, and quadruped (fourlegged). They first appear in the fossil record during the late Triassic, around 230 million years ago. They include the largest animals to have ever lived on land. Along with all other dinosaurs (except for birds), they became extinct 65 million years ago. This poster shows all the largest species. Some were close to 200 feet long - the length of four school buses. Also shown are some of the more unique species. Camarasaurus vertebrae were hollowed out or riddled with passages and cavities, which inspired its name, “Chambered Lizard.” Mamenchisaurus had a 31-foot-long neck that comprised half of the body length of the animal. For size comparison, the neck of a giraffe is shown next to it in the same scale. The unique body structure of these fascinating animals is explored. Could they rear upright like a horse? Other interesting topics are intelligence, teeth and diet, eggs, skin texture, and social behavior. Created with the help and cooperation of the American Museum of Natural History. A306 Pterosaurs Pterosaurs were the first vertebrates known to have been able to fly. They suddenly appear in the fossil record during the late Jurassic period, around 220 million years ago. These first species were fully developed and have baffled paleontologists as there are no fossils to provide even a hint as to their origin or how they evolved. They are often referred to as pterodactyls, but that name refers to members of the Pterodactylus genus. There are many others. Pterosaurs became extinct at the end of the Cretaceous period, 65 million years ago. They were an incredibly successful group of animals. During the 155 million years that they dominated the skies above the earth, they constantly evolved into new forms. This is the first poster to explore their incredible diversity. The picture captions cite biological and common names, where the fossils were found, when the animals lived, and their wingspan. Each is also accompanied by succinct text explaining its uniqueness and importance. At the bottom of the poster, anatomical illustrations and text are used to explain the differences between the wings of birds, bats, and pterosaurs. This is a truly beautiful poster. The species were illustrated by a paleontologist and are shown against a dramatic sky background.
