Applying the poster edges filter to the selected triceratops yielded an engraving-like image, so I hunted through my stock image collections and found an engraving of a cyprus swamp that seemed to fit. I embedded the triceratops in the swamp using masks and adjusted the tone to match using a levels adjustment layer. The frame is a cut out oval with a bevel layer style -- the texture is from the EyeCandy fur filter.
