I was able to acquire a nice Giant Thresher (Alopias Grandis, non-serrated form) that came from Lee Creek (Aurora, NC). It's the third in my collection. I'm curious to know how rare/uncommon they are from that location. Giant Thresher shark teeth seem to be found with some regularity in South Carolina, although they be from the Oligocene. Giant threshers are also found in Maryland along Calvert Cliffs (Miocene). I've seen a few other Giant Threshers from Lee Creek in other people's collections and have heard about a few others. Curious to know, especially from some of the long-time LC collectors, how often they heard of a Giant Thresher being found in the mine. Daryl.

A few more of my favorite finds from the Aurora Fossil Museum Matrix - I am not even half way through the two gallon bags of matrix from my purchase! SO MUCH COOL LITTLE STUFF!! Being micros, all specimens are under 1/4 inch Shark Teeth: Top Cookie Cutter, Sand Tiger Bottom : Catshark, Unknown Not Shark Teeth: Top: Not sure what this one is, Second one is Raja Bottom: Fish Porgy and Dasyatidae Top: Echinoid spine and tubercle Bottom: Burrfish mouthplate and a bit o' Crab I think Not sure about these but I am leaning towards Turtle on both top and bottom specimens.

I'm going through my vertebrate collection and making sure the labels are correct before I start forgetting everything haha. I have here two small bones that I found from the Lee Creek Mine in NC. I collected the white one from the Pliocene Yorktown Fm, a marine fauna. The brownish one was collected from mine spoil, so it could range from Miocene-Pleistocene. I have them tentatively identified as marine mammal phalanges, but these are somewhat out of my comfort zone. Thoughts? I"ve tried to show the two bones from all angles. If better or additional photos or needed, please let me know Thank you in advance!

This is from the Aurora North Carolina matrix. I have tried to ID this little tooth (4 mm) and have been unable to find a match. It seems different than any of the others I've come across. Any help will be appreciated! Plus here's a few other things that I'd love an ID if possible! Thanks y'all! 1. 2. Also found this tooth (assuming it is probably a fish tooth?) 4mm also 3.and then this thing - also thinking it's something "fishy" ? 6 mm

Thanks to a post from Candace ( @thelivingdead531 ) I found out about the Aurora Fossil Museum's box o' matrix that they sell! (all moneys benefit the museum, which was a bonus). I got two Gallon Bags of matrix to sift through and wow....some really great stuff! They send a really good ID sheet too. But of course, there's even more info here on the FF! So here are some of my favorite finds so far. I've only gone through about 6 cups of matrix!! SO MUCH MATRIX! I havn't really done much ID'ing yet (the shark teeth) but my favorite by far is the crab stuff....love those pincers!! And the color of the shark teeth is amazing....purples and pinks -maybe that's why it's Aurora? I certainly have enough to keep me entertained for the upcoming week (which, if you aren't in Texas....we are going to be in the single digit temps (Farenheit) with predicted 4 inches of snow....which is COMPLETELY unprecedented to have two snow storms in a winter...) I'm staying INSIDE with my space heater. And looking through matrix.... Crabby bits Ray Teeth Shark Teeth Fish Teeth Echinoid, Coral and Gastropod a Vert and some unknowns...probably fishy bits

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

I have a quick question for those that have bought and gone through their micro matrix from the Aurora Fossil Museum. Did you wash it before going through it, or wash it after you've found your fossils? I got the pack with the mini screen for sifting, but I'm a little afraid to wash it all first and risk losing tiny teeth. How did you all go about doing yours, or what do you think the best way would be?

Hello. I found this tooth about a year and a half ago in the spoil piles outside the Aurora Fossil Museum. I was wondering if anyone could help me identify it? I think it might be a mako tooth (Isurus oxyrinchus?). Also, does anyone know why one side of the root is much smaller than the other? Is that damage? Or maybe due to jaw position? Thanks for your help.

ID requested: Miocene (micro) sharkteeth from Lee Creek Mine (USA)
ziggycardon posted a topic in Fossil ID
Hi everyone! Little over a week ago I recieved some new bags of microfossil matrix and this time there was a bag with material from the Lee Creek Mine, Yorktown Formation, Aurora, North Carolina, USA (Miocene, 14,5 mya) This material is quite rich in shark teeth as I found little over 90 shark teeth in it. I have photographed a couple of them already and posted them in my microfossil topic. But since I doubt I will get many help with the identification of the teeth there I am going to repost the first batch of teeth here (I apologize for the repost admins) and upload the rest of my finds from that material in this topic from now on. I have tried to ID some of the teeth with the help of the website Elasmo & the paper "Geology and Paleontology of the Lee Creek Mine, North Carolina, III by Clayton E. Ray and David J. Bohaska", but I feel like my eyes aren't enough trained yet to distinguish enough to make proper ID's on all of the finds, so I not all ID's will be a 100 % correct I am affraid. Here are some of the first teeth I photographed. I would be gratefull if some of you could help my ID some of the teeth of verify /correct some of the ID's I have come up with. If the photo's aren't clear of good enough, just let me know and I'll try to make some more/better ones. Thank you in advance! The first tooth which is by far also the favorite in the bunch: Tooth 1: a Sphyrna zygaena tooth? Tooth 2: a chunk of Galeocerdo sp. tooth Tooth 3: another Galeocerdo sp. tooth Tooth 4: This one is a tooth which I have a hard time identifying as I feel it has a lot of features that return in different teeth. Physogaleus? Sphyrna? Loxodon? Tooth 5: another I haven't managed to ID yet. Tooth 6: Carcharhinus sp. Tooth 7: could this be Negaprion sp.? Tooth 8: Tooth 9: Scyliorhinus sp.? Tooth 10: Megachasma sp.? Tooth 11: Megachasma sp.?.jpg.07507fea64bddeeb831b2fd240c955b9.jpg)

From the album: Aurora/Lee Creek Mine Micro Matrix
This assemblage came from one cup (about 340 ml) of micro matrix from Aurora Fossil Museum. Oddly, they are generally much larger than most of what I found in the rest of the matrix. They are all from either the Pliocene or Pleistocene. See album description. -

I have a dozen teeth from Aurora, North Carolina that I believe to be from the toothed whale Squalodon. Instead of uploading photos of that many, I'm uploading a few that are representative of the dozen and detailed photographs of three of these. For context, the first tooth here is 2.5" long and 1" wide at its thickest.

I have here a tooth from Lee Creek, Aurora, North Carolina. I believe it to be Kentriodon. It's a hair above 1". Does this seem accurate? If so, could it potentially be narrowed down further yet? Thank you, Bellamy

hello all, it's been a while since I've been on. I hope you are all doing well in these trying times. I recently purchased a series of large mammal phalanges from Lee Creek. They're clearly Yorktown (Pliocene). While they seem to resemble seal phalanges, they're awfully large (14-15 cm). I'm wondering if they are walrus instead? Does anyone know if the last Smithsonian Lee Creek volume (Vol 4) is available online as a pdf? Alternately, are there easy "tolls" that I can use to distinguish, or does anyone feel comfortable making a distinction? Thanks!

I found this the other day in a bag of Aurora micro matrix. It's only about 3 mm long. Could be Miocene, Pliocene or Pleistocene as all three run through the mine and the matrix is thoroughly sifted together during mining operations. There appears to be a root and possibly two tips broken off?

Hi. I was wondering if anyone could help me identify these shells. Thanks for your help. The first two shells were found in the spoil pile outside of the Aurora Fossil Museum in Aurora, North Carolina. They come from the Lee Creek Mine and are from the Pungo River Formation. I don't know much about shells in general, but I think this comes from a scallop. I unfortunately don't have any locality info on it.

This came from a bag of mixed micro matrix from the Lee Creek AKA Aurora Mine which was sifted, sifted again and sifted some more. It is a mixture of material from three formations: the Miocene Pungo River Fm., the Pliocene Chowan River Fm., and the Pleistocene James City Fm. After digging through reputable resources covering the area from Maryland down to Florida, the administrators and I have mostly ruled out Miocene as none of the references mention anything similar from that time period. Three names are given for the species from the Pliocene and Pleistocene. Ward and Blackwelder (1987) identify Arene pergemma, with a description and illustration that looks very much like this gastropod and is about the same size, from the Lee Creek Mine1. The Paleobiology Database says that Arene pergemma is an old name and gives Marevalvata tricarinata as the accepted name2. The Neogene Atlas of Ancient Life says that Marevalvata tricarinata is no longer valid either, and has this species recombined as Arene tricarinata3, a name which actually predates Arene pergemma4. The Neogene Atlas does list a very similar shell, Arene agenea, which lived during the early Miocene. However, A. agenea has a circular aperture while the mystery shell has a more elliptical aperture from every angle I use th photograph it. A. agenea also has less defined ornamentation than the shell in question. Furthermore, the Neogene Atlas only lists A. agenea as occurring in the Chipola Fm. of northern Florida4. All agree that the fossil occurs only in the Pliocene and early Pleistocene from North Carolina down to Florida, but only mention them occurring in North Carolina in the Pleistocene Waccamaw Fm. further south and the Late Pliocene Duplin Fm. to the west. Ward and Blackwelder discuss a couple similar species in their discussion of the genus, but give no identification for them in the book I have available. Given this, I think this specimen is most likely from the Pliocene. However, after deliberating with a TFF malacologist, this might be a new undocumented species altogether that could be from any one of the three time periods and formations.

I found this - almost missed this - while sifting through some micro matrix today. I'm guessing some sort of fish tooth, but can anyone confirm? From Aurora Fossil Museum, Aurora, North Carolina. Lower to middle Miocene from the Pungo River Fm. It's so small that I have a hard time getting the camera to focus and my microscope cam just made it a big, black blob, so I apologize for the soft focus. That course rug it's sitting on is a piece of fine velvet!

Hello everyone, newbie here, and thank you for helping me figure out what I found. All those were found in a pile of mixed gravel/sand/sea shelves in Raleigh, NC but it was imported, I believe from the Aurora, NC mine several years ago. Anyway, I was lucky enough to find several items including bones and dozens of shark teeth but I am not familiar with a few of my findings. Hopefully you guys can help, Thanks again!!!
