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.? -

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

I found this tooth in a bucket of matrix yesterday. It has the hint of cusplets on each shoulder and this kind of throws me. I have my own impression of the I.D. of this tooth but am looking for other opinions. I have thousands of Lee Creek teeth in my collection and have gone through countless gallons of matrix, but this tooth just looks odd to me. Any thoughts or suggestions are appreciated.

Hope everyones week is going well. Over the past week I found a couple teeth and something that looks like a fried egg. I just wanted to get some confirmation regarding the teeth and I have no idea what the 3rd item is. Thanks for all the help. 1. I think this is symphyseal tooth but not sure. 2-3 MM 2. Thresher shark 3MM; not sure because the root seems to fat. 3. Fried Egg looking thing; It is the same on both sides 2.5MM

Hi. Hope everyone had a great week. I found this tooth this morning as I continue to go through more of the Lee Creek Matrix. I am somewhat confident that this is a Finetooth shark - Carcharhinus Isodon. I wondering if someone can confirm if I am correct on this one. Thank you so much for any feedback.

Hi. I found this and at first I thought it was a ray tooth but I can not find any examples of it. Maybe because it is worn. This leads me to believe that maybe it is fish rather than ray. Any insight would be greatly appreciated.

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 have been spending the past covid months going through Lee Creek matix. I dont know what I would have done without it. I have found hundreds of things and still have a ton to go through. Since I post pictures last I took the advice given and purchased an aultrasonic cleaner. WOW, what a difference it makes. Thanks for the input on that @MarcoSr @Al Dente @ClearLake @CocoAnyway here are 10 unique finds that I need some guidence on. I appreciate any feedback! 1. Is this a fish tooth? To me it looks more reptilian. Dare I say Croc tooth. I know its not but I am still searching for my first. Plus I have heard they are super rare for Lee Creek. 2. The only thing that slightly looks close to this tooth is a Bramble Shark. But I think this is going to end up as some type of symphyseal tooth. 3. Smooth Hound Shark 4. Never saw anything like this before. I am assuming its fish 5. Alien tooth or another Symphyseal tooth 6. Just cool looking and small 1-2mm 7. Fish Jaw but what kind? about 2-3mm 8. Next two pictures are NOT the same tooth. I found two that look very similar. Pinfish? 9. 10. Fish tooth?

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. Found some neat stuff in the Lee Creek Matrix today. I believe most of it is fish/skate teeth. If anyone get help with ID it would be much appreciated. Everything is 1 - 2mm. Also, Can somone explain how to get of the dirt on these teeth? I soaked them in hot water and some of it came off. They are so tiny to scrub. What would be safe to soak them in? Thank you for any feedback! I believe these two teeth are Rhynchobatus Teeth #1 #2 #3 I think this is some type of skate tooth but not sure what type #4 absolutely no clue #5 I believe this is a fish tooth
