I have a bunch of different sizes and quality fossils from when I lived in Florida. I've collected them kinda like arrowheads throughout my youth. I've been meaning to do something with them for years but haven't come up with a good idea yet. So I'm gonna let some go. You could put them in a tank or use for decoration or even make necklaces out of them. I have all shapes and sizes from different prehistoric sharks.
I think you can buy a set of synthetic jaws you can put them in to display them. Greg has one, he might be able to tell us where he got it.
