I found this little guy in Summerville last weekend. It looks like it's curved and twisted on the bottom of the blade. Opinions?

Here's the image. It didn't post correctly in the first time.

I can't tell how thick the root is from the pic, but it looks like a parasymphyseal Contortus tooth to me. Is the root thick enough for the tooth to stand up on it? if so, it's probably a Contortus.

Hi Tom,
It does have a knob on the front of the root that would allow it to stand up at an angle if flipped over. So I'm guessing that the unusual curve of the blade would be normal for a Contortus tooth?
The crowns of Contortus teeth are significantly twisted (contorted) , and the parasymphyseals are usually smaller, and have less of a twist than the other positions. This site has some good examples of these teeth, including the parasymphyseal. From the home page here, click on the link for shark teeth fossils on the right side of the page, and then click on Galeocerdo Contortus.
I concur with Tom. It's also not uncommon to see the tip of the crown recurved like this specimen. I love these teeth and have over 6000 of them.
Daryl.
Tom/Daryl,
Thanks for all your help with identifying this tooth. Even though it's not the pathological tooth I thought it was, it's still a great addition to my collection. I'll try to post a field report soon with my other finds from last weekend's adventure.
