Pathologic Fossil Dusky Shark Tooth

Interesting story - I'm picking up all the fossil bones that I have strewn across the bone garden in front of our house because we're moving (somewhere local, of course) and I'm not leaving them behind. Anyway, I had a duffle bag full of bones from the last dig where I found a megalodon tooth about a month ago. I finally got around to washing the bones off, and I did it in my sifter to catch anything cool that was in the sand. Good thing I did! This double tipped tooth was in there. Gotta love the patho teeth!
