I purchased this geode couple months ago and finally figured out what it is Dunkleosteus trapped in geode also parasites worms and other biological creatures fluorescent orange with uv light I was told this is impossible but it's real look at crystal formation its a fish look at joint in neck bone plate 2 front teeth and I have pic that looks like xray I believe fish is trapped with actual flesh and bone have pics to prove just need someone legitimate to authenticate it most amazing discovery in history seriously 100 % authentic prehistoric fish not fossil but actual fish!!!!
