I had a pretty great day at Aurora yesterday. This was my third time there ever, and I managed to convince my boyfriend, father, and uncle (none of whom are as fascinated with fossils as I am) to tag along. I mostly stayed at the pile with my boyfriend, and was a bit bummed out because it seemed like everybody but me was finding decent sized megs and chubutensis left and right! I did find a nice snaggletooth though, and bought a few buckets to take home since we had to leave earlier than I expected. I'm so glad I did, because in the first bucket I found a pretty big meg tooth fragment. I also found a few more dolphin teeth and a nice cow shark tooth. I always seem to find the things I want to find, for the most part, because I remember remarking to everybody in the car that I wanted a few more dolphin teeth and at least one half decent cow shark tooth since the only other one I had came from Purse back in Maryland.
Here are a pair of head-scratchers that I found i at LC. The first is from the Pungo River Fm I thought was a bivalve steinkern, but it is not carbonate, which one would expect in the lime layers of the formation (that, or phosphate, and itisnt phosphate). There is still some matrix on it. So that leaves me with maybe some portion of the bulla/ear region of a marine mammal, but that's purely a guess. The second is from the Pliocene Yorktown Fm, and the material appears to be the same as that of cetacean tympanic bulla. But it doesn't look like one, or like anything Ive seen from a cetacean. Any ideas? thanks
Found this in the Pungo River Fm of Lee Creek (Miocene). I'm pretty sure it's a Carcharhinid, and more than likely a lower tooth, but that's all I got. Half-inch in length, smooth cusp (even under micro), strong foramen, curved root base. Maybe there is a slight notch in the blade (left side, labial view), but I can't be sure that's not a nick. My first thought was Lemon Shark, but the tooth is too triangular, and the base of the root has a very definitive curve. Then I thought hammerhead of some sort. Photos in order: Lingual, Labial, side Ideas?
