> birds are dinosaurs
Not that I doubt that, but how does DNA help, when we have no DNA samples from dinosaurs?
Birds are dinosaurs because they are in the clade dinosauria. Their closest living quadrupedal relatives by genetic distance are indeed crocodiles.
But you're right, it is the fossil record that provides the strongest evidence.
