Dinosauromorpha |
Orthinodira subclass is a division of the archosauromorpha class. It contains two chief superorders, dinosauromorpha and pterosauromorpha.
The prior, dinosauromorpha, contains lagosuchians, and their famous descendants dinosauria, which, in turn, are believed by most researchers to be the ancestors of modern birds. The latter, pterosauromorpha, which are famously the bird-like, or flying reptiles we perhaps the first vertebrates capable of true flight.
