Fischer Technical Company™ Dinosaur Poster Set of 4, Laminated

Description

• This set includes four laminated posters
• All posters are 24 x 36 in
• Titles included 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.
