Hi friend! You cant evolve out of a clade. Birds are dinosaurs. Dinosaurs are fish. Humans did not evolve from monkeys. Humans are great apes, which evolved from primates. Monkeys also evolved from primates. Humans and Dinosaurs evolved (skipping many steps here) from fish. Every terrestrial animal that is not an arthropod is a fish. Hope this clears it up.

Edit: As far as your PS, crocodiles emerged at the end of the Permian mass extinction as pseudosuchians, diverging from the ornithosuchia and avemetatarsalia archosaur groups
