This Encyclopedia of dinosaurs is a comprehensive listing of all genera that have ever been included in the superorder Dinosauria, excluding class Aves (birds, both living and those known only from fossils) and purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that are no longer considered dinosaurs. Many listed dinosaurs have since been reclassified as everything from birds to crocodilians to petrified wood. This application Includes 1300+ Items including corresponding images and write ups which include Description, Location, History and Stories behind the find and Much More. And now includes Prehistoric Reptiles as well. Also Contains two different dinosaur quizzes to test your knowledge and abilities.
