Santa came early here in the north country. I've been after one of these for a while and I finally got one in the mail today. It's an early, transitional form, Palaeocarcharodon orientalis. Very coarse serrations near the root fading to almost smooth at the tip. One root tip was glued back on as these teeth are very prone to damage, but I can ignore that because it's almost 2 inches long, and they don't get much bigger than that.
