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.

Picked this up in Post Oak creek, Cretaceous. Not sure what I'm looking at, don't recognize usual root, is that a chunk of gum attached to tooth? Looks like it was part of larger piece that broke off and left the impression beside it .

Hello, Does anyone have an idea as to what kind of shark tooth this is? I found it in my late father's home and don't remember how or where he came about the tooth, although most certainly somewhere in the southeast USA. Thanks in advance for any help!

From the album: Sharks
I ran out of room in the other display, so I split the collection into extinct/extant species. I probably still need another riker! For scale, the big great white tooth is about 2 1/4" slant height. In red are species that are endangered or critically endangered. The only teeth I regret having are the modern Makos, I had gotten them for comparative reasons (both are anterior, left is upper, right is lower). The fossil Mako is actually an I. desori (a big one!), but I included it since it's so morphologically similar to the extant species, and a few people would say they're synonymous. Species included (obviously will grow): Alopias superscilliousus Alopias cf. vulpinus Sphyrna zygaena Sphyrna mokarran Carcharhinus obscurus Carcharhinus plumbeus Carcharhinus brachyurus Carcharhinus falciformis Carcharhinus leucas Carcharodon carcharias Carcharias taurus Galeocerdo cuvier Isurus oxyrhinchus Lamna nasus Negaprion brevirostris Rhincodon cf. typus -
I found this today at Ocean Isle Beach, NC and need help with identification.

One of the newer teeth in my Megalodon tooth collection. I have been collecting Megalodon Teeth for some months. now. The tooth is around 4 8/16 inches big and has some restoration on the root. I love the colors and serrations! Show me your South American megalodon teeth!

I found these three teeth in the town of Carrières-sous-Poissy in France, near Paris. They were mixed in with small rocks and lots of small nummulite fossils all along a country road. Two of them are shark teeth, I'd be happy to have some help with the ID for those. The third fossil is also a tooth I'm guessing, although I can't tell what type. All three are quite small, around 1cm long as you can tell from the ruler. I apologize for the quality of the images and the stark contrast, thanks for any help!

I found this tooth several years ago while searching micro matrix from Colorado, which I am now certain is Mancos Shale. Never mind. Mystery solved. Lesson learned=I need to wear my glasses when trying to ID teeth from pictures lol It’s a Catshark or something similar.

I can't figure out if this tooth is a normal Otodus tooth or if it's something else. I think it looks like megalolamna paradoxodon tooth, but to my knowledge, they aren't found in Morocco. I would appreciate any help or I'd on this tooth. It doesn't have any serrations and it has only two cusps. It's 3,5 cm from root to tipp.

I’ve had this tiny 1mm shark tooth in my collection for 3 or 4 years and am no closer to knowing what it is than when I got it. The person I got it from had no idea either. I don’t believe it’s batoid, looks shark to me. Again its tiny, roughly 1mm. It stretched the limits on the micro eye it’s so small. It is from the Ampe Clay Pit, Egem. It has some odd asymmetry going on. I have thought perhaps it was an odd Catshark of some sort but I don’t know about that now. Could it be a weird Orectolobiformes of some sort ? I don’t like admitting when I’m clueless but I really have no idea on this one lol Any ideas or suggestions are welcome !

I received some matrix from @sixgill pete a while back in a TFF auction and picked most of it a while back and ID'd the bulk of the teeth and other material. Lately I have been going back through some of my sharks teeth and looking more closely at items I was unsure of These three teeth are one such group out of this matrix. I have read Purdy et, al (2001) a bunch of times, looked at elasmo.com for hours on end, read dozens of threads on here and am still a bit confused/uncertain. So, I figured why no just ask and get several more opinions, I always appreciate what folks here have to offer. The teeth are shown in the pictures below and it is mostly the big (relatively speaking) one (#1) I am most interested in. The two smaller ones (#2 and #3) are fairly similar looking although #3 is much more worn, and are likely small symphysial teeth from ???. Tooth #1 is 7.4mm tall and about the same width. My first guess (wish?) was a Megachasma even though I know these are extremely rare out of the Lee Creek material. It sits very flat on it's broad base and the crown is slightly curved lingually, but not as much as many depictions of this genus. There are no serrations on the crown, but it is somewhat worn and the tip is missing, so that could factor in. I have looked at all the various posts on here of possible Megachasma's, most of which are probably not (more likely symphsials of any number of sharks) and looked at Don's Megachasma that Dr. Shimada confirmed and still was not 100% convinced one way of the other. This tooth does not look dissimilar to what is in Purdy or the description written there. Some of those crowns are not very "bent" either, nor is the specimen that Don posted very curved as far as I can tell. But then I see many posts by @MarcoSr and @Al Dente and others that show symphesial teeth from Hexanchus, Carcharhinus, Hemipristis and Galeocerdo that all bear similarities. So, I ask what you think and appreciate any and all insights that can be offered. And here are some close ups of the crowns on each of the teeth just in case that adds anything useful.

My first post .... This fossil tooth was found on the beach in northern Florida last week. Out of hundreds of shark teeth, this is the first one I have seen bent like this -- perhaps a pathological variation on a normal shark tooth, or maybe a whale shark tooth? What do you think?

Let me know what you guys think!! I would love to get an idea of the time period and what shark it came from! Thanks in advance!
