Aurora/Lee Creek Cow Sharks   Lee Creek Mine, Aurora, North Carolina, USA - Notorynchus primigenius
I"m having probs posting photos in the forums, so en lieu of posting in the "Let's See Pics of your displays", I figured I"d post some this way. Here are my Cow Shark Teeth from Aurora/Lee Creek. Only a few are from Pungo, most are Yorktown Teeth...
Cow Shark Tooth   Lee Creek Mine, Aurora, North Carolina, USA - Notorynchus primigenius
IMO, This is my wife's best find this weekend. Funny story... When we first got into the pit, I was looking for teeth to show my wife the type of deposits to look in to find teeth. I spotted a little outcropping of Yorktown with a bull shark tooth on a little pedestal. I called her over and told her to look in front of me. She bends down, looks for a minute, and then picks up this tooth. She didn't see the one I saw, but found the awesome one I missed!...

Aurora Cow Shark Tooth   Lee Creek Mine, Aurora, North Carolina, USA - Notorynchus primigenius

I found this Aurora Cow Shark tooth in the footprints of another collector. Surely they would have picked up this tooth had they seen it. They must have been looking for a big megalodon sitting out in the open and just missed it. Anytime people ask my advice how to find the big shark teeth in Aurora, I always tell them to look for the little ones. Its easy to see a big tooth sitting out in the open, but how often do you see that anymore? Almo...

Pathologic Cow Shark Tooth   Lee Creek Mine, Aurora, North Carolina, USA - Notorynchus primigenius
I found this nice cow shark tooth in the Yorktown formation, and I assumed it was Hexanchus. I showed it to Pat Y. at the end of the day, and she was kind enough to tell me the difference. You can draw a straight line down the cones on Notorynchus teeth, while the primary cone on a Hexanchus is out of whack and messes up the straight line, even on juvenile specimens. Even though its not what I initially thought it was, it has a pathologic curvature to one of the cones ...
Lee Creek Notorhynchus teeth.   North Carolina, USA - Notorynchus primigenius

Here is a group of Notorhynchus teeth I collected in the Lee Creek mine near Aurora, North Carolina. Most of these I found myself, in the Pliocene Yorktown Formation and they were collected over a number of years. This frame has the best lower Notorhynchus teeth, from Lee Creek, that I have in my collection. I took the picture just as the sun was setting and it didn't turn out as well as I would have liked.
