Hi! I am a new artist that has recently found some interest in animal bones and skulls. I just need some help with identifying what roadkill is and is not salvageable. I am not looking for skins, all I am interested in are the bones. What is a quick way to tell if they are not all messed up and broken on the inside? Is decomposition faster and cleaner if I remove the skin first? I am hoping to make a "decorated bone string-puppet/sculpture." Hopefully I can get my hands on a full Deer or Horse skeleton. Thanks!
