Well, there is a vivid detail that the Bible provided about the 'dinosaur' called Leviathan (Job 41:19-21):
19 Firebrands stream from his mouth; sparks of fire shoot out.
20 Smoke pours from his nostrils as from a boiling pot over a fire of reeds.
21 His breath sets coals ablaze, and flames dart from his mouth.
Does this mean that some dinosaurs could breathe fire?
