Hi, I found these teeth a while back and just never could find a solid match, does anyone know the species? They were found on the Kaw river in Kansas. Thank you!

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!

Hello fellow fossil hunters! This is my first post here and I came here for some expertise on identifying a tooth I found recently on a trip to Portugal. I found it at a beach in the Algarve region. I read that locally they have mako sharks and blue sharks but I’m not sure what animal it is from. Since this is my first (maybe) fossil find. I appreciate any guesses for ID-ing this tooth, thanks in advance! 🙏😁

Hello all! I was wondering if anyone could help me identify some shark teeth. I was gifted most of these teeth from the late @caldigger. A lot of them came from Shark Tooth Hills and a few I believe were misc teeth he had kicking around. I had labels for them at some point but a recent move found the note associated with them missing. The first 9 photos are shark teeth from Doren (@caldigger). The teeth in the last 3 photos I purchased when I worked at a local rock and gem shop. I’m pretty sure they’re plain ol’ otodus teeth. I would greatly appreciate if anyone could give me some insignt into what they could be so that I could label them appropriately All the best! -V

Hi everyone - does anyone know offhand what non-Cretaceous formations are present at Holden Beach, NC? I have not been able to figure it out. For example, what formations might this tooth be from, and what is the age range? I assume Pliocene onwards?

Long overdue to post about some of my NC finds from earlier this year! First up was a very exciting trip to the NC Triassic to look for a variety of plant fossils, which were my first Mesozoic plants. Beautiful white coloring on some of them as well, the matrix is extremely soft (you can easily scrape it with your finger nails) so I've done some experimenting with how to best consolidate them without damaging the visual effect. Not a ton of variety at the site, but they are abundant and sometimes surprisingly well preserved. I have found Otozamites hespera and Otozamites powelli, as well as a few other kinds of plants. I also disturbed a "hibernating" lizard, initially I was concerned that my digging had injured him, but after a some time in the sun he scampered off seemingly no worse for the experience.

Recently just got back from a trip on Tybee Island! During this trip I went out looking for shark teeth several times a day, and even did a tour with Sundial Charters! Overall in 6 days I found over 150 shark teeth and countless other fossils! I'll be posting them on here! Here's the coolest tooth I found actually on Tybee, I believe it's a Great Hammerhead.

Hello again, dear forum users. At this point in time, we began to study a point with a Cretaceous (we believe that this is Campanian based on the fauna of shark teeth and lithology) fauna. These are mainly shark teeth and fragments of cartilaginous fish. But there are also such mysteries. The main version is that this is either a fragment of coral or fragments of sea urchin needles. Particularly interesting is the strange formation on one of them, as if something had attached itself and was about to grow - a brachiopod? The third question is about the tooth of synechodus, is it a tooth of synechodus lerichei? I'm right? Best regards, Anton.

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.

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
