I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I have no idea what kind of dinosaur this is supposed to be. It has a long neck like a brontosaurus, but also a spiked tail.
The cover art is pretty accurate, though. If you look closely, the man in the yellow coat has a little ball strapped to his left shoulder. The man is Conway, and the ball is the little alien doctor, which is probably lifting the dino up with its mind.
