I'm not what you expect

Jumping in the bandwagon of the latest news about Spinosaurus I have decided to update my version of this dinosaur.

Following the ideas of a shallow water wader, swimmer of mud-crawler living stiles, which seem to make some sense, I propose the idea of the elongated spines as base for a camouflage display. 

If the animal lived basically near the ground, fishing, lurking, swimming or crawling, the presence of a high back profile seems out of place. So, what if the spines were covered in fuzzy bristles that help to break the animal's profile? This would bring a resting or swimming Spinosaurus the aspect of a floating island of vegetal matter or just a bunch of riverine plants.
