3/4" Mosasaur Tooth

I held this in my gloved hand while I finished scanning the remainder of the gravel in my screen, not realizing what I had. Looking like a large crab claw I picked it out without looking at it closely, so I it wasn't until I was ready for the next screen that I realized it was a mosasaur tooth! (The fact it was 20 deg F and snowing didn't help my attention span either)
