Following the advice of my fellow TMPer's, I went to Dollar Tree and picked up some of the dinosaur skeletons. I cut them into pieces and the results are below.
I have enough to finish some loose pieces to throw around.
I also used air dry clay to create the obligatory walk through rib cage.
The terrain for this game is really coming together. I still need to build a cave and some type of alter, and a bunch of trees.
