>>2127924Dinosaur fossils are nowhere near as durable as regular rocks. UV rays are energetic and destructive, with the additional effect of heating the fossil. The first thing that happens is a bleaching effect, and after a while the entire thing will fracture and crumble. The image is of a claw I found in two pieces, with the second lighter piece being found a few months later. You can see the damage that the sun does in such a short amount of time.
