Okay so found this very strange shark vert today. I think it’s shark, anyway. Doesn’t match any bony fish I know. But also doesn’t match any shark. Measures about an inch across and an inch long. @hemipristis @Al Dente @MarcoSr

While sorting through some of my more recent finds I came across this very small shark tooth I found. My initial thought was tiger, but it doesn’t seem to match any Galeocerdo species I know of, nor does it match P. Contortus. Any help would be appreciated! @hemipristis @Al Dente @MarcoSr

Any help would be appreciated

I found this tiny tooth while searching through some matrix collected from Post Oak Creek in Sherman, Texas. I believe the formation there is the Eagle Ford Group, Cretaceous. For scale, the grid in the pictures is 5x5mm, the tooth measures just under 3mm. I've been looking into Palaeogaleus and Galeorhinus, but neither seem to fit (I don't see any bulge with a crown that overhangs the root). Are either of these even known from this formation? Any thoughts on the ID of this tooth are appreciated, thanks!

Disclaimer: I'm still not 100% sure if the layer I'm hunting in is the basal Atco, but I am under the impression that it is for now. Hopefully I'll be able to do a hunt at Midlothian with the DPS some time soon to get a reference for what the Atco is really supposed to look like. In the past month, I've taken another visit to my little Atco spot to try and learn the place a bit better. I scouted farther upstream and downstream as well as another creek not so far out. There were some pretty cool finds, but I'll keep the story short since I've already covered this locality in a previous report. After a bit of creek walking, I was relieved to see that the latest storm had washed out some fresh conglomerate for me to start splitting at the main gravel bar. Most of the teeth present in the matrix are extremely weathered from reworking, but now and then, a pristine specimen can be revealed and carefully extracted. The first of these discoveries came from just the second rock I had picked up. Some of you may relate to that moment of disbelief when you open the two slabs and realize you are face to face with a huge tooth in mint condition. I hate having to glue broken teeth together, so I proceeded with extreme caution. Still not totally sure if this is Cretodus houghtonorum or Cretodus crassidens, but for now I am tentatively calling it C. houghtonorum since its cusp is more gracile and seems to lack the ovular shape of C. crassidens. One interesting feature of the tooth is the presence of a an extra little cusplet which can be seen in the labial views between the central cusp and distal cusplet. Whatever species it may be, it is a first in my collection, so I am am pretty content. I traveled a little ways up a feeder creek and came across the root of a decently sized Cretalamna gertericorum. The matrix was hard, so I ended up having to clean it at home. Sadly the central cusp was really banged up. Tough to spot, but the root of C. gertericorum Cretalamna gertericorum. On the left is the new specimen and on the right is one from my first visit to the site after recent repairs. At a later gravel bar, I finally found something sticking out of the matrix that I had been really hoping to find. Some of you may remember that my last trip to this spot had yielded a prearticular tooth to a meter long pycnodont fish called Acrotemnus streckeri. These fish are also documented as having pharyngeal teeth. I managed to finally pocket one at this site and one at the later site I'll soon cover. I can't say for sure these are from A. streckeri, but their large size does make it a candidate. Pycnodont pharyngeal in situ A couple of pharyngeal teeth I will tentatively assign to Acrotemnus streckeri. It's kinda neat these teeth share the bluish grey color of the prearticular tooth. Before I show off the final find from the main Atco site, I'll quickly go over the second location I visited. The plan was to locate the Atco there as well, but with all of the modifications made to the creek, I wasn't able to find the source of the Atco rubble I found scattered along the stream. Nothing remarkable was found, but that isn't too say I didn't come out with at least a dozen small teeth. Here a couple pictures of some interesting geologic formations. Huge ripples were found on a lot of the washed out matrix. Located in the uppermost Arcadia Park was this limy layer that was rich in vertebrate material and gastropods. I came across this giant concretion that really stood out. I wonder if anything's inside it. And here is an overview of the smaller finds from the trips: Top L to R: Squalicorax falcatus, Cretodus houghtonorum, and Cretalamna gertericorum Bot L to R: Xiphactinus sp., Acrotemnus streckeri, and various ptychodus Back to the main site, as I was wrapping up the day, I came across some hardened material on the shale bottom of the creek bed above the conglomerate layer. Usually these sort of things are only broken oyster bits, but the shape and density of this one seemed odd so I went in for a closer look before noticing how dark the object was underneath the algal growths. It soon became clear that this was a string of 5 very large fish vertebrae and I begun working around the fossil to pop it out whole. Thankfully, I was able to do just that and the sight as I flipped it over sent me jumping up and down. I scoured the surrounding area, but did not locate any more of the fish. Makes me imagine one day 90ish million years ago this chunk of fish was all that was left after a shark attack or maybe something of the like. After bringing it home, I was able to scrub off the larger chunks of algae, but a hard "calcareous" layer remained attached directly to the bone. I tried soaking it over multiple nights in a bleach water solution and slowly worked off pieces with a dental pick during the day. The plan was to use the other side as display, so I wasn't too concerned with abusing the algal side, but of course I would have liked to have as little damage done as possible. One of the verts was offset, so it quickly broke off from the stress of picking at it. Later another vert came off, but this wasn't an issue as I could easily glue them back later. The work was tedious and took time. On the display side, I worked off the shale with a needle and frequent brushing. Slowly the form become more and more apparent. Soon enough, I decided it was time to get the paraloid out. On a site with so many professional preppers, I'm sure this doesn't look all that impressive, but I am suuuper happy to have this on display and proud of the work. It's fun to hold and imagine the sheer size of the beast these bones once belonged to. I hope you all enjoy it as well. Thanks for reading

I realize it's quite the task ID'ing shark/ray vertebra... However, I am hoping some of you will be generous enough to share your input on these finds from a recent trip to Summerville, SC. Larger vert measures 1-3/4" X 13/16". Smaller guy is 3/4" X 5/16" and I'm hoping for sawfish on that one, which would be my first! The last pic is simply for your viewing pleasure, because it's the most unique looking vert I've ever found with that root leaching! I also understand that I might not get far with the bug guy, but thought it was large enough to get detailed enough pics to point me in the right direction!

Hi. We were at Bawdsey today and found a few tithings. I know lots of people who find shark teeth there but wasn’t sure if these are something or nothing… Thanks Tom

I recently visited the Canadian Museum of Nature in Ottawa and was able to purchase some fossils from the gift shop. Picture 1 is my personal favorite, it was labeled as a shark tooth, but I haven't been able to identify a species yet, any help is appreciated. Picture 2 is an ammonite, duh Picture 3 is a smoothed Orthoceras Picture 4 is a collection of smaller shark teeth I got together in a box.

These are all sorted and very similar, may be more than one species. Size: 0.25 to 0.33 inches Coll. Location: Eocene, Gosport Sand, Clarke Co., AL

A quick group shot, once I made it back to the car:

My first ever trip to this location. I gave it a go for a few hours today, and I managed to find a few fossils. Nothing here that will blow people away; but I was "very thankful" that I was able to find fossils, without having any local knowledge. It was a learning experience. The location Information, is in the attached photographs.

Almost everything was found yesterday at Peace River (FL). I’m still new to fossil hunting. I do my research but still need help - there’s a lot to learn. TIA for anyone who takes the time to let me know what I’ve got here! In order, I think I have: -Deer ankle bone -Scapula? Turtle shell? -Glyptodont scutes -Horse/camel incisor? -Manatee/dugong tooth? -Shells (I know nothing about these but love these two-wanted to share) -Gator/plant? Pattern is only on one side -Deer tooth? -Camel/deer tooth? -Stumped - too many teeth look too similar…tapir? -Recent shark tooth finds (contents of the final picture were found on land in Sarasota county and not at the river) I think that’s more than enough for now I have quite a few horse/bison/camel/llama/etc teeth that I also need help differentiating, but I want to try a little more before asking for help. Any good charts/info that help point out differences in these would be greatly appreciated! Adding some pics of recent shark tooth finds just for the fun of sharing. If you see anything special (rare/pathos/etc) that I need to know about, please let me know! Again, thanks in advance for all the help! Any ideas appreciated - if better pics/measurements are needed, just ask

I think North Texans will relate when I say that now and then, the urge to take a drive out to the NSR and spend the day hunting some Campanian gravel bars can spontaneously take complete hold. I had one of those moments just after the series of heavy rains and powerful winds our region encountered some days ago. Previously, my luck with weather at the NSR had been rather poor. Each time, the temps were either nearing a hundred degrees or only just above freezing, making a full on adventure crossing muddy waters and crawling atop unshaded gravel beds too much to handle. I had yet to experience a proper adventure at this historic site, so I decided that this week would be the one where I changed that. Luckily, my friends @PaleoPastels(Lari) and Cole where kind enough to invite me out to their special spot along the river. After waking up bright and early, I got in my car and followed the rising sun. After jumping out of our vehicles and exchanging brief greetings, we quickly slid our way down to the shale bed and beelined for the first bar. Cole has a bit of an aversion for water, so he stuck around at the entrance for most of the day while Lari and I got our clothes wet hopping from bar to bar. The weather and water temp were absolutely perfect, and the lack of footprints assured us it would be a productive day. It's not often you beat the crowd to a place as popular as this! Although I maintained measured expectations coming in, the sheer variety of strange and interesting fossils/artifacts that are known to come from this area kept me on my toes from the outset. When we arrived to the first bar, we started off strong, picking up a variety of shark teeth. Lari had an eye for them, immediately spotting a few super big Scapanorhynchus texanus, a staple of the Ozan Formation. Despite my protests, she was very generous in donating a few to me due to my limited NSR collection . Finally one I spotted myself! Scapanorhynchus texanus Scapanorhynchus texanus of the day. Some may be Carcharias samhammeri as I am still working on differentiating the two. In between crawling the gravel, I did some sifting which yielded a few interesting specimens including Squalicorax kaupi, Cretalamna sarcoportheta, Carcharias samhammeri, and a vole tooth which I will ignorantly assume to be Pleistocene in age. Cretalamna sarcoportheta, Squalicroax kaupi, and Carcharias samhammeri Sifting also yielded a plethora of shark vertebrae and I was fortunate enough to come across a beautiful spiral shark coprolite. I found one solitary coral which I assume is Trochocyathus sp. Shark verts, shark coprolite, and Trochocyathus sp. As I scanned the gravel looking to spot a complete Cretalamna, I was instead met with the first mosasaur tooth of the day! It was mostly in tact and showed some nice detail. I was relieved to know the entire trip was already made, and I could spend the rest of my time playing with house money. The only other mosasaur tooth previously in my collection has a beat up crown, so this new specimen certainly complements it. Don't know much about mosasaur genera in the NSR, but I will go with Tylosaurus proriger for now. Throughout the day, we also found tons of very large Enchodus fangs and jaw sections. I'm so used to finding these teeth in their miniature forms as I sift for micros, I almost forgot how big they could get. Lari did good with spotting the Ischyrhiza mira rostral teeth and quickly built up a small collection. She was nice enough to give a large one to me. Top: Fused fish vert and Pachyrhizodus tooth. Bottom: Enchodus jaw section and large fangs. Ischyrhiza mira By now we had hopped a couple of gravel bars and there was still plenty ways to go. It took me longer than it should have, but reaching the third bar finally brought me a large tumbled mosasaur vertebra. Not far from it, there was a section of finer gravel. Used to the routine, I once again got close to the ground and began scanning every pebble. After tossing the millionth shrapnel of shark tooth, I finally locked eyes with the most perfect mosasaur tooth I had ever seen. As I picked it up, I could tell something wasn't right, however. Of course the best side was on full display, but the rest of the tooth was cleaved cleanly off. Oh well, at least it'll look nice in pictures. Not long after, I found a second mosasaur tooth that was decently complete and hooked albeit tiny. Two nicest mosie verts. A slice of an exquisitely preserved mosasaur crown. The next oddball find came awhile later. My initial impression was that it might have been a segment of a Xiphactinus tooth, but the curvature suddenly ended along one of the edges of it. At this sudden end, there were two columns of small protrusions running longitudinally. I was debating on throwing it out, but my history of carelessly tossing neat finds convinced me to play it safe and take it home for identification. I'm glad I did because after the hunt, I immediately googled my hunch and it seems to be correct. This is a fragment of a hybodont spine! I wish I could pin down a more specific ID, but the info on them seems limited. I will say that, out of Moss Creek, I had found a tooth belonging to Lonchidion babulskii last year which could be the culprit. Quite an uncommon find for the NSR! Wondering if any shark experts here might have any ideas @ThePhysicist@Al Dente. Hybodont fin spine. Lonchidion babulskii is a candidate. By the penultimate gravel bar, I thought the best finds had surely been made. All day Lari had been talking about how this was THE spot to find Globidens teeth and how every visit she would find at least one fragment. Well, the walkable land was starting to run out and she expressed how disappointing it would be not to come across one that day. I find Globidens to be really interesting, but I think of it as one of those finds I would never expect to make on any given hunt. For me, not finding one would not define the day as a let down. As I was beginning to form those thoughts into words, I reached down to pick up a circular fragment of a tooth with a peculiar texture. Finding the right angle of light soon revealed the undoubted best find of the day: The top of a Globidens sp. crushing tooth! The whole day I had been hallucinating "finding" Ptychodus teeth. Funnily enough, this may very well be the tooth that ended their supremacy as shell crushers of the WIS. Seems too coincidental that Globidens suddenly appears right around the last occurrence of Ptychodus. I wonder if they directly competed Ptychodus out of existence or if Ptychodus went extinct on its own and mosasaurs simply filled in the niche . I don't think the Globidens of the Ozan Formation has been formally described yet. Globidens sp. Mosasaur teeth of the day! Despite having hunted for over a year in the creeks of Austin, I am surprisingly bad at spotting artifacts. Throughout the span of the day, the both of us had found a few chert flakes, but no sign of anything more even as I was trying to make a conscious effort to spot one. On the same bar as where the Globidens sp. was found, I noticed a worked edge of stone so big even someone as archaeologically blind as me could never miss it. Without an ounce of self control, I yanked it from the sand before I could finish yelling the word "arrowhead"! I seriously need to work on milking the moment . I did a little bit of searching online later and found that the point is likely a Darl or Hoxie. Both put its age in the thousands of years! Darl or Hoxie point. It measures 8.5 cm in length. On the way back, we kept our eyes peeled for anything we may have missed. I was sifting random spots of gravel, but not having the most luck. Lari casually handed me rock with a pearly white exterior and triangular shape. It was the most textbook mastodon I had ever seen, but she wasn't very impressed with it. She told me she had many of these already and that nonmarine fossils didn't interest her. I won't say I understand her terrestrial prejudice, but I will withhold my complaints since it meant I had acquired my first significant chunk of proboscidean . Mastodon enamel, mammoth enamel, and vole tooth. We finally reached Cole at the entrance. In our absence he had wondered off the other way and found a neat spider to pique his entomology interests and pocketed a few fossils. We managed to make it out by the mid afternoon, but I was so exhausted and content, I couldn't bother checking out any other spots along the river. The spoils of the hunt were amazing, but most of all I was happy to finally experience a classic hunt on the NSR as I had seen so many post about before. Doing it with a couple of friends made the adventure even better! Sadly this place has got not much time remaining, so those of you who have stumbled upon this post, maybe take it as a sign to give this historic spot one last go before the opportunity floats away. Thanks for reading!

I was finally able to take a trip to the NSR in 2023. We had a good 11 foot rise so I was optimistic. My whole goal this trip was to find a point, I couldn't find one to save my life, I however did find a few cool fossils. I don't know if i just don't have the eye for it or if i am just looking in the wrong places. The last two pictures are of an item im not sure about anyone have an idea? Possibly a set of fused vertebrae with the two end ones broken off? The haul The vert The mosasaur thing The in-situ And the I don't know what this is

I found this in the Bahamas. Does anyone know what kind of tooth this might be? Thanks Heather

Over the last two years I have been able to collect a small but diverse group of shark and other chondrichthyan teeth from Pennsylvanian deposits in Illinois. Actually, all but one of the teeth are from one exposure of the La Salle Limestone of the Bond Formation- the other tooth was found in some roadside rip rap limestone in Central Illinois which seems to share many species with the La Salle, but unfortunately I have no way of determining the exact origin. Here is the first tooth, this is the one collected from rip rap in northern Champaign County. It is a cladodont type tooth, although unfortunately most of the main tooth and some of the cusps are missing. The tooth is 15 mm across at the widest point.

Hello Group. I have had this concretion for years, unopened. It fell of a table while outside, during a move. I finished the breakout manually. If memory serves me, It came from the Lake Texoma shoreline during a drought. It looks like pics i found of shell crushers teeth. I didn't want to do anything to it without knowing anything about it. Any help in identification would be greatly appreciated. Thoughts and comments welcome. Please excuse the poor photography. I will get better pics soon. This "stone" almost went in the garden last week.
