Diaphram present in crocodile?

Apparently this saying applies to those scientists who believe that dinosaurs cannot possibly have a diaphragm, because it is simply not possible for an animal with a diaphragm to evolve into an animal that breathes with air sacs, like birds, since the transitional stage would have a life-threatening hernia in the diaphragm.......
Our text book says diaphram is mammalian character but exceptionally present in crocodillic class of reptiles. But some site say diaphram absent in crocodile

Yes, crocodilians have a diaphragm. In fact the baby theropod dinosaur Scipionyx was so well preserved that some scientists can see that it, too, had a diaphragm. Nevertheless, since some scientists believe that birds evolved from a dinosaur, their belief has prevented them from seeing the diaphragm. As someone once said, "Seeing is believing. If I didn't believe it, I wouldn't have seen it." Apparently this saying applies to those scientists who believe that dinosaurs cannot possibly have a diaphragm, because it is simply not possible for an animal with a diaphragm to evolve into an animal that breathes with air sacs, like birds, since the transitional stage would have a life-threatening hernia in the diaphragm.
