Like our our other prints, our Dinosaur Evolution poster is a high quality colorful & laminated poster that is a must-have for anyone interested in Dinosaurs. Paleontologists are rewriting some of 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 dinosaur 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. The 24" x 36" poster is sealed in a heavy crystal clear plastic laminate making it waterproof and very resistant to damage.
