There are way more than just two dinosaurs. If you're asking for two examples of dinosaurs, then I'll just say Tyrannosaurus Rex and Apatosaurus.
The two major groups of dinosaurs are the Saurischia (lizard-hipped dinosaurs) and the Ornithischia (bird-hipped dinosaurs). These groups are distinguished by differences in their pelvic bone structure.
Dinosaurs that walk on two legs are called "bipeds". The term applies to all animals that walk on two legs.
No, not all carnivorous dinosaurs walked on two legs. Some carnivorous dinosaurs, like the theropods, were bipedal, walking on two legs. However, others, such as the ceratosaurs, were quadrupedal, walking on four legs.
There were a lot more than two dinosaurs that had a length of about 10 meters. Two examples include Neovenator and Amargasaurus.
Two of the earliest dinosaurs to be named were the Iguanodon (a plant-eater) and Megalosaur (a meat-eater).
There were no true dinosaurs that could fly. But two flying creatures that lived during the dinosaur times were Pterodactyl and Ornithocheirus.
Birds branched of from a group of dinosaurs called theropods (the two legged dinosaurs consisting mostly of carnivores) in the late Jurassic period.
