A-Z Dinosaurs List

This list of dinosaurs is a complete listing of all dinosaurs genera that have ever been included in the super order Dinosaurian, not including class Aves (birds, both living and those known only from fossils) and merely vernacular terms. The list of a to z dinosaurs includes all universally 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. The list contains 1278 names, of which approximately 888 are considered either valid dinosaur genera or nomina dubia.
