Wow. I'd love to see a pic of it. I'm real curious to know where along the cliffs you found it. I know there isn't going to be another just lying there in the same place, but I've heard that some of the rarer species of sharks (ie. Paratodus, A. grandis) when found, are usually from the beaches south of areas like Brownies and Willows.

Thanks for sharing the pic. Cool tooth. I knew that it must be a lateral tooth given the size you indicated. I'm a little surprised that cusp after the main cone is recurved back towards the main crown. I see that alot on upper Hex teeth. Besides the size, I think what helps to ID the tooth are the serrations on the mesial edge of the main cone. Sevengill upper lateral teeth have serrations but not as many.
