Paleontologists are rewriting the rules of animal classification. The traditional system introduced by Carl Linnaeus has been largely discarded in favor of the cladistic system that shows how species evolved over millions of years. Our Dinosaur Cladogram visually portrays the evolution of the most well-known species. Over 50 representational species are shown; each has a caption citing species, where they have been found, when it lived and its size. Informative captions explain the changes. A few of the illustrations are shown below.
Over the past six years, many new species of feathered dinosaurs have been discovered. As it turns out even Velociraptor may have had feathers. We watched a bunch of them hunting in packs in the movie Jurassic Park . We now know they were great big chickens. But then they would not have been as frightening.
This is a truly incredible poster. It shows 18 magnificently detailed illustrations of the various species of feathered dinosaurs. The three insets across the top explore Feather Evolution, Wing Evolution and Flight Evolution. Across the bottom, additional insets explores "Brooding Dinosaurs?" Dinosaur Family Tree, Parts of a Feather and a special section that discusses Discoveries, Discussions and Debates. This is truly a comprehensive overview of an exciting cutting edge subject. Some of the illustrations are shown below.
The central design shows all members of the Tyrannosaur family, in scale to each other. They are arranged chronologically, left to right, by the time they first appear in the fossil record. The insets cover many important topics. The two at the top explain the distinctive anatomical characteristics and show the important ancestors. The captions cite species, pronunciation, size, when lived where fossils have been found and important milestones in evolutionary development. Those at the bottom cover new discoveries, such as the recently unearthed feathered tyrannosaurs and the results of the amazing growth studies recently announced by the Field Museum. Behavior discusses family relationship and the controversial question as the T. rex being a hunter or a scavenger. The last one lists all North American museums where T. rex skeletons are on display. n found will be shown on a matched set of maps - one showing the position of the continents at the time and the other where they are today.
These are some really strange critters. Although well documented, most are rarely mentioned in popular literature. Cryolophosaurus ellioti is a good example. It had a bizarre crest running across its head. Due to its resemblance to Elvis Presley's 1950's pompadour hairstyle, it was nicknamed the "Elvisaurus." The paleontologist who described the ugly Majungatholus atopus, said, "It's the kind of face that only a mother could love." The weird Masiakasaurus knofleri had forward-facing teeth, jutting out from its lower jaw; it really needed a good orthodontist. Stygimoloch spinifer sported bony spikes on its head. Tsintaosaurus spinorhinus had a horn protruding from its forehead, resulting in it being called, "the Unicorn Dinosaur." Plus there are nine more bizarre creatures.
The Weird Dinosaurs have been magnificently illustrated by a leading paleontology artist to ensure anatomical accuracy. Fact-filled captions provide essential data and a description of the unique distinguishing characteristics. This poster includes exciting new discoveries, largely unknown to the general public.
