OK, So I've been tasked with giving a presentation on my sharks teeth & bone collections that I've found over the years. I wanted to give a good bit of background and try to alleviate many questions. I am having trouble classifying sharks teeth as a fossil. Are they a Cast? I also read about permineralization...but I don't think that's what most teeth are.
Any advice would be greatly appreciated as general research had me more confused than when I started.
PS, I'm a Green Mill Run/Aurora local that spent more time in the creek than in classes while at ECU.
