Reconstruction of Miragaia longicollum, the "sauropod-mimic" stegosaur from the Late Jurassic of Portugal. The arrangement of plates and spikes, as well as the shape of the dorsal plates, is speculative due to the incompleteness of the fossil material from this dinosaur. Here, I have depicted the plates as covered by more extensive keratinous sheet which changes their shape.
