Greetings Gang!
I found these while sifting through a creek in Northern Mississippi. Specifically at the W.M. Browning Cretaceous Fossil park. I'm pretty sure that the top four are "Goblin Shark", although I could be wrong. I don't know if the bottom ones are, or another species. This is the first time I did this, so happy with my results.
Any thoughts would be greatly appreciated.
Joe
