I recently bought a couple of toy dinosaur skeletons from poundland and have actually followed through on my intention to turn them into a couple of basic terrain pieces. I didn't do much too them, simply stuck them to a piece of card painted green and flocked, and gave them a simple gyphon sepia wash. It seems to have worked out alright, I'm not claiming they're fantastic, but for the price paid they will do the job nicely.
