My first non-ptychodus shark tooth. Unique shape on these 'Crow shark' teeth. 3/10/24 #VM1© CC BY-NC

Found on the coast of Hilton Head South Carolina USA. I am quite unsure of what this is, it’s very eroded and might ether be unidentifiable, or just a funny looking rock. However, I find it looks very tooth like, with one wide end, and one pointy end, as well as a cavity that is open at the wide end and gently tracks further into the “tooth” My first thought was a premolar of some sort of primitive whale sans the roots. But that seems unlikely. Please share your thoughts! I’d love any sort input and if you would like a better picture of a certain angle, let me know! Here are the pictures 1. Front side 2.Back side 3.Right side 4.left side 5.Top side 6.Bottom side And here is a video of the specimen rotating! (ignore the sparkling putty, it was the only option I had to get it to sand up nice while still being visible at all angles) IMG_0199.mov

Hello all. I have this one shark tooth from the London clay and I’m really stuck on its identity. I’ve already ruled out Striatolamia due to the lack of lingual folding and shape of the cusplets. The only two options I have are Hypotodus verticalis and Glueckmanotodus heinzelini, but it has features of both and also has features that both do not present. It’s from the London Clay formation at Walton-on-the-Naze, UK. The age is early Eocene (Ypresian). Any help would be appreciated.

Hey TFF! First post! Not making my appearance with a bang, but had a decent quick trip to the Potomac, about an hour and 15 minutes. Nice handful of sea glass, decent amounts of ray plates and turritella. A few solid sand tigers. And what I believe to be a small, busted otodus in the palm of my hand. I usually always come away with at least one small complete otodus, so when I don’t, it makes a great day fossil hunting turn into merely a very good day 🤷🏻♂️. Let me know what you think!

Got this shark tooth from a rock show a couple of years ago (when I was not into fossil collecting) and seller said it was from morocco, that is all I know as far as this tooth goes. (I am not a shark tooth expert by any means, but I can tell that the root is composite and not original) Thank you for your time!

Is it a truly natural megladon tooth?
Gregorsamsa posted a topic in Is It Real? How to Recognize Fossil Fabrications
I recently bought this tooth from an online auction site. It is listed as being 100% natural. I am a beginner to collection fossils, but especially the back looks a bit patched up. Hope some of you more knowledgable collectors can help me on this. This last picture I was sent by the seller, when it was still in it's matrix. -
Polyacrodus aff. brevicostatus, Lower Glen Rose
Mikrogeophagus posted a gallery image in Member Collections
From the album: Glen Rose Formation
Polyacrodus aff. brevicostatus, Canyon Lake Albian, Cretaceous Jan, 2024 I believe it is likely P. brevicostatus instead of P. parvidens because it is low crowned, has more than 2 pairs of lateral cusplets, and has labial nodes present on all cusps/cusplets. I'll admit it's hard to be super confident in an ID as most papers are pretty old/inaccessible.- 2 comments

From the album: Pleistocene
Carcharhinus limbatus, Port Aransas Beach Pleistocene Mar, 2024 Drove down to the Corpus Christi area for the first time to scout some promising sites and the famous Port Aransas Beach. Sadly, I almost got totally skunked. The only saving grace of the day was this C. limbatus tooth I sifted out of a pile of shells on the crowded beach.-

Hiya everyone I bought a lot a while back, going through it I found a rooted tooth that wasn’t mentioned, my best guess is due to the shape it’s a whale tooth, also there was a shark tooth unlike any other in my collection, any help with ids would be great thanks.

Hello everyone, I was recently looking at one of our local beaches. I didn’t have a lot of time so went where most people go. Sometimes even though it is picked over you might still find something special. I often think, there could be just a few mm of sand covering up something special! I saw this sitting there waiting for me and thought. That’s cool. Level of excitement maybe a 6 out of 10? I hadn’t seen associated verts like this at this site and was thinking “shark or fish” (p.s. photos are at home after finding it in better light. But pretty much what saw on the beach) I was leaning towards shark and then flipped it over. Excitement went to 9/10!! I couldn’t believe what I was seeing. This looked like preserved shark “skin” or at least in situ dermal denticles. A first for me at this site. If you’d like to join me down a wormhole on learning about shark dermal denticles. Read on! This is a normal journey I take as I learn as much as I can about each fossil. Every fossil has something to teach. About the environment the animal lived in or the creature itself. I’ve learnt a lot about biology/ecology this way. if you zoom in under the scope, there are 2 layers of denticles. The top one most visible in the above photo seems to be looking at the base of the denticles from underneath, like a skin has folded on itself these look like the “roots” of the denticles. In the photo below. Each one about 1-2mm across In the photo below is the underside of the top of some denticles A tricuspid type. A few mm across. So zoomed in more than the above photos. these look like the “drag reduction” type tricuspid denticles top left in the figure below. This figure shows that sharks will have different types of denticles on different parts of the body. The proportions and types differ depending on ecology. Pelagic (requiring drag reduction) vs bottom feeding (demersal) requiring protection from abrasion. I searched around the specimen and found a few examples looking at the top of the denticles. Below. Unedited Photo above with red sketch to highlight features below. denticle is a couple of mm across. You can see the crests typical of the drag reduction type. below: looking side on at an individual denticle. The “root” at the bottom and tricuspid denticle on top. so how to move forward? The matrix isn’t acid soluble. But I’d like to be able to clearly see some complete denticles. Gentle air abrasion? I’m not sure if an ID to family will be possible. I have shown a shark tooth/denticle expert (from Japan) and he thought we could narrow it down to Triakidae (hound sharks) or Pentanchidae (deep water cat sharks). The age range is Miocene- Pliocene for the coast in this area. I think Late Pliocene for this based on lithology. So now…..where is the rest of the shark? Thanks for following along!

From the album: Hell Creek Formation Microsite
A collection of microscopic (~ 1 mm in size) teeth from the orectolobiform, Galagadon. These are very difficult to collect, as it requires sieving a large volume of sediment and searching the concentrate under a microscope.-
