Rhincodon cf. typus Pungo River Fm., Aurora, NC, USA a minute tooth from the biggest fish in the sea - the whale shark. Being filter-feeders, their teeth serve no known function and are considered vestigial. -
This specimen was found in micro matrix purchased from the Aurora, North Carolina Fossil Museum. Description: Teeth are very similar to the genus Galeocerdo with finely serrated, long, thick and warped crowns; pronounced notch, small serrations on heel of distal side. Undulating margin and fine serrations on mesial edge. U-shaped root with a prominent protuberance on lingual face and transverse groove (Fig. 5.10). Physogaleus contortus differs from the genus Galeocerdo in having very prominent and bulging root with the deep notch, and a much more erect crown in lateral view.

Identification: Ray, Clayton E. and Bohaska, David J. 2001. Geology and Paleontology of the Lee Creek Mine, North Carolina, III. Washington, D.C.: Smithsonian Institution. https://doi.org/10.5479/si.00810266.90.1 From Page 99 & 100: "The crown of the Lee Creek Mine tooth (Figure 15o) is sharp, slightly curved lingually, and has a perfectly smooth surface. It is compressed laterally, and the cutting edges are distinct but dull. A narrow and relatively long apron descends onto the lingual face of the root. The roots of these teeth are bulbous and are wider at the mesial and distal sides than at the crowns, and they possess a well-marked central foramen and transverse groove. A pair of prominent lateral foramina are located high on the mesial and distal sides of the root, and the basal area of the root is marked by small, irregular vascular openings. These teeth are identical to those of the extant species, Rhincodon typus, Smith." Whale shark teeth are very obvious, with a tall, bilobate root, and a narrow crown. More on ID.

This past summer I found this bone at the Miocene Pungo River dig pits of the Aurora Fossil Museum. The bone matches the shape of the end of a crocodile pubis from what I have seen online. Crocodile material isn’t common from there, but I know it’s occasionally found. Does this look like a correct ID? The bone doesn’t match anything cetacean that I’m aware of, too thin to be a limb bone or rib head, not the right shape for a phalanges or vertebral process as far as I can tell.

Soooo a few days ago new material was dumped at the Aurora Fossil Museum. Well, I made the trip there before the Saturday crowds, and was well rewarded!!! These were the best finds of the day =p btw the stuff underneath the shark verts are 2 stingray spines, a filefish vert, a burrfish bone, a beat up dolphin jaw bone, and what I think is some type of fish skull cap

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
