Don't draw conclusions out of the information you retrieve from this Dino Data site only. Always check your books, library and other resources. The cladistic lines are only to be seen as an indication of the path. You will find some names under the "classification" button that arn't showed at the dino pages. Not all given names of dinosaur groups are on this moment available at this site. Paleontologist don't always share the same views and it isn't the intention of Dino Data to show the different views. Again always check other information sources to compare the information. DinoData couldn't be what it is without the help of many. Special thanks to all the members of the Dinosaur Mailing List and DinoForum for sharing information.
