Found in micro matrix from the Pungo River Formation, Aurora NC. Maybe a claw or teeth?? regards Ken

We got a very small amount of Lee Creek micro mix and it didn’t yield much in terms of volume but we did get a couple of excellent Hammerhead teeth, a Galeorhinus, and a few others. There are a couple of unsolved mysteries though. Up first is a 3mm mystery partial tooth. Under the scope this tooth bore no similarity to any other found. I looked through EVERY shark and batoid tooth picture for Lee Creek on Elasmo. The tooth that came the closest was actually Megachasma but I’m convinced that can’t be correct. The root is not intact and I can’t do any better on the pictures for now.

I dug in the Pits of Pungo out front of the Aurora Fossil Museum for a few hours. Heres the haul. The shark teeth Phosphate nodules Coral Sea life burrows. Posterior lemons and coppers These teeth are sooo small I don't even know why I picked them up Bryazoa...? My favorites Some of those famous Aurora makos ( isurus oxyrinchus I think) What I think are posterior isurus oxyrinchus's though the one in the middle one looks like it has a burlette? meg? I would appreciate any feedback on these Two nice Hemipritis Double cusped carcharhinus taurus? Alligator claw core? Bird? Sea urchin spines ray teeth Fish/shark verts and partials. I would appreciate if someone s=told me the difference two of them stuck together Bone frags whale verts and frags Shells Can someone help ID them? I can't seem to find any papers or websites I also spent all my birthday money on their little gift shop. Heres what I got from there. I would be happy for any IDs for them. (I like things labeled) Dont know where from St. Claire. PA fern. What is the age and formation of this locale? Morrocan trilobite pyrite amethyst this is definitely my longest post even though its just pictures mostly

As part of our recent tour through the Carolinas, Tammy and I stopped for a bit at the Aurora Fossil Museum (Aurora, NC) to walk through the museum itself as well as to have fun playing in the "sandbox" across the street. The local phosphate mine dumps fine gravel from the mining process in a big pile (two, actually) across from the museum so visitors can hunt for fossils in the fossil-rich gravel without having to deal with the liability issues of coming to the open-pit phosphate mine itself. I'm not quite sure if the fossiliferous gravel represents the Pungo River Marl (Lower Miocene), the Yorktown (Early Pliocene), or a mixture of these and other formations at the mine so the stratigraphy is muddled and likely impossible to determine from this off-site location. We were in luck in that the gravel piles were "turned" that morning exposing fresh material at the surface. It had also rained persistently for several days so the piles were a bit of a sticky mess. I think this made it all the more fun for the young fossil hunters we met on the piles. I was only interested in collecting some of the finer material to look through back home for micro-fossils and so we made use of our sifting screens to remove the larger shark teeth helping the kids to increase their finds. http://www.thefossilforum.com/index.php?/topic/87495-epic-carolinas-roadtrip/&do=findComment&comment=950166 I've been busy since returning from this trip but I did manage to wash the sticky silt from the Lee Creek micro-matrix we collected from the piles and dry and store it for later perusal. I had to try a sample of this to gauge the fossil density and get an idea of what was hiding in there as this was a novel micro-matrix source for me (though it has been offered several times on this forum). I've been quite impressed with the density and diversity of mostly tiny shark teeth and other items I'm used to seeing in marine-based micro-matrix. There are some novel species that I'm not used to seeing in micro-matrix from South Florida. In particular, these nice little shark teeth with the cool side cusps were a welcome surprise. They are roughly 3 mm across the root and about 4 mm high. As these popped out of the first small sample that I picked through, I'm guessing these are quite common and well known by the folks familiar with this material. I'm hoping @powelli1 or @sixgill pete or @Al Dente might be able to provide an ID from the image below. Even more interesting that the shark teeth was what appears to be a claw core that also appeared in this small sampling of the micro-matrix. I don't know my claw cores very well--unless it is an enormous ground sloth core from Florida (still high in my Florida fossil bucket list). I don't even know enough to know if this would be from a bird, reptile, or mammal but I'm sure this forum will come to my aid and offer some clues to what I've found. In particular, @Auspex should be able to quickly made an avian/non-avian determination. As a size reference, this item is about 8.5 mm in overall length and around 4 mm at its widest width. Looking forward to another bit of forum-based education tailored to the items that have recently encountered. Cheers. -Ken

Found this today on the bank of the pungo river in NC. I can't ID this one. Miocene Era, I believe. It's about 3/4" long. I am assuming it is a tooth, but not sure of what.

I purchased some bags of matrix from the Aurora Fossil Museum and have been having a lot of fun searching through them. It is Miocene, the Pungo River formation. However, I have some that I could use some help with on ID'ing. The hash marks are 1mm: - Is the first a Sevengill shark tooth or just a broken edge of a serration? - Is the 2nd pic of croc teeth? - The 3rd looks like dermal denticles, but the big one also looks kind of like the start of a barnacle. - what kind of teeth are in unknown2.jpg? - what kind of teeth are in unknown1.jpg? - are these teeth enchodus? - the last two look like pycnodont teeth. Some are concave on the bottom and the others are convex. Are they both/either/neither pycnodont? Thanks for your help.
