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.

These were all found in southeastern Oklahoma. I find these occasionally while working in rivers. These were found in a sand bed river. I just want to be able to put a face to these teeth. I have several other shark teeth that I have found in the same area, but will hold off on posting for now. Thanks a lot!

While getting together some fossils for the rolling auction I came across this tooth I had bought a few years ago. I dug around on my folder of screenshots I take of fossils listings, so I don't forget what information the seller provides and it was pretty devoid of info. It was sold as a megalodon tooth. No location or any other info...yeah I know that would be handy... I assume but the looks of it, it probably came from the Carolinas or Florida. On to my observations. Seems to be no serrations on it. It looks like a nutrient pore in the center of the root on the lingal side...if I remember correctly meg's don't have that. Looking around on the internet I want to venture a guess of an anterior Carcharodon plicatilis tooth?

The weather's finally warming up here in DFW, and with that, it's time to move on from the comforts of dry land and return to the ways of creek stomping. These past few months, I've been mostly hanging around cuts and construction sites within the Washita Group, and to be honest, I've gotten a little sick of it. During that period, I steadily accrued a sizable list of potential Eagle Ford and Atco locations within the metroplex, and I was itching for the opportunity to finally go and check them out. Yesterday, I circled a few spots on the map and hit the road. Well, the first couple of sites were more or less complete duds. Stop 1 was situated in the Turner Park Member of the Britton. Lots of cool stuff can be found here and it's one of the more prettier formations, but I'm still trying to figure it out. I only spent about 30 minutes there, and nothing really impressed me. Nevertheless, I was at least rewarded with my first ptychodus from DFW (yeah it took awhile). Stop 2 was a famous site within the Camp Wisdom Member of the Britton. There were some interesting cephalopod specimens to be had, but nothing worth taking home. I did not lose hope, though. I knew that my third site was the most promising of the bunch and I accordingly saved most of the day for it. Stop 1 in the Turner Park, and my first ptychodus from DFW (P. anonymous) The Atco lies just above the Arcadia Park Formation of the Eagle Ford Group in DFW. It's famous for being densely packed with a diverse array of vertebrate material dating to the Coniacian, mostly concentrated within a thin layer dubbed the "Fish Bed Conglomerate" just at the contact of the Eagle Ford and Austin groups. The key to finding this layer is to look for matrix that is highly concentrated in phosphatic pebbles and fossils. Down in Austin, I think it gets a bit overshadowed by the Eagle Ford. In DFW, however, I would say the Atco reigns supreme. After a decent drive and trek, I stepped into the creek and began my descent through the Austin Chalk in search of this coveted conglomerate. It was difficult to tell where exactly I was stratigraphically since the Arcadia Park seems to be a bit calcareous whereas the Austin Chalk can be a bit marly. Where the calcareous marl ends and marly chalk begins is tougher to differentiate in practice, especially for someone less experienced like me. I eventually reached a large gravel bar and decided to pause the walking and have a look for any clues. I didn't find anything out of the ordinary in my initial scan, and almost picked up my backpack to move on. However, I took a moment to take a closer look at what I had first subconsciously written off as concrete. In this chunk of rock, I saw hundreds of tiny rounded phosphatic pebbles. Once my eyes reached the edge of the block, I spotted the unmistakable serrated blade of a Squalicorax falcatus tooth. There was no doubt, this was Atco matrix! The material was noticeably greyer than I had expected. Down in Central TX, the Atco is about as white as the rest of the overlying chalk. With all of the odd bits and bobs intermingling with the grey rock, it really does look like something manmade. I pulled out the rock hammer and began searching the bar for more chunks of fish bed conglomerate. It's amazing the things your eyes can miss when you unknowingly tune things out. There were very obvious shark teeth encased in many of the rocks I had walked by earlier. I collected several larger pieces and sat down to begin extracting teeth. Found my nicest shark vert yet. Unfortunately, it was super fragile and lots of it broke apart in cleaning. My first oddball tooth from the Atco. It has the shape of Cretalamna appendiculata (in the strict sense), but the presence of labial striations pushes me towards a posterior tooth of Cretodus crassidens. It also notably has doubled cusplets on one side. That same tooth post extraction. It broke in half by the time it got home, so I'll be doing a bit of consolidating. Funky little guy. There were some very large slabs of Atco conglomerate washed out atop the gravel bar. I did some hammering to break them into more manageable chunks so I could rinse them in the flowing creek. As I split one of the large slabs in half, I let out an annoyed sigh as I saw a decent Cretalamna appendiculata tooth crumble from the point my hammer had hit the stone. I tried to push that misfortune out of my mind as I perused across the newly exposed surface for any other teeth. I quickly spotted some fine serrations poking out of a chip of matrix that had just come loose. It was a Squalicorax falcatus doing its best chameleon impression. Please don't break please don't break Voila! By far the largest Squalicorax in my ever-growing collection! Florida megs better watch out... My constant hunt for micros at home adequately prepared me to keep an eye out in the field. I was able to spot a couple of Ptychotrygon triangularis oral teeth throughout the day. I also managed to find a mediocre Scapanorhynchus raphiodon and my first decent Ptychodus whipplei! Managed not to lose it in the gravel. Ptychotrygon triangularis Lots of beat up Scapanorhynchus raphiodon that day Ptychodus whipplei. The bits and pieces I have from Austin look like they were crapped off a cliff by a coyote as some Texas fossilers like to say. After getting a nice sunburn, I decided to get up and explore more of the area to perhaps find a source for this matrix. I spotted a little tributary that seemed promising and had a gander. Some outcrops have a beauty that only fossil hunters can truly appreciate... You who are reading this, I know your mouth is watering A little ways farther, the source is found. As I walked up the small feeder creek, I periodically inspected the pieces of fish bed conglomerate that were scattered in the way of the flowing water. One ball of matrix had an unsuspecting appearance, but something about it wouldn't let me leave it alone. There was what initially seemed to be some part of a bivalve erupting from it, but the color and texture gave off enamel vibes. After hammering off some chalk, I still couldn't figure it out. I eventually extracted the entire thing. It was extremely smooth and came to an edge at the top. The surface was mostly bluish gray and semi translucent. It took a second for the cogs in my brain to start working and realize I'd seen something very similar before. @Jared C and I have been recently discussing Hadrodus, and, of course, one of his best discoveries is a large fragment of Hadrodus hewletti of which shares many visual characteristics with the object in my hand. I was excited to realize I was holding the tooth to a gargantuan pycnodont fish. Just after extraction Occlusal view and side pics For scale. Stay tuned for the identity of this monster After this discovery, my stomach growled, signaling it was about time to head back. This was only my first excursion in the Atco of North Texas, and it had already proven to be one to remember. For sure, this will be a site to return to. As I walked along the banks towards my exit, my eyes were still honed in on the ground as is the curse set upon every fossil hunter. I usually don't find anything on my return walks, but I was delighted to see the sheen of black enamel poking out of some Atco chalk just several feet above the fish bed conglomerate. I popped it out and quickly identified it as Ptychodus, though the species I was unsure of. At the moment, I think it is P. atcoensis as it seems to be a good match with a specimen in Hamm's paper on the Atco. It's got radiating ridges and a marginal area similar to some P. anonymous. That paper mentions Meyer (1974) suggested that the taxon could be transitional between P. mortoni and P. anonymous and I certainly understand that reasoning. It's a little beat up, but that's a rare species and a special one. In situ Radiating ridges and concentric ridges in the marginal area as expected for P. atcoensis Once I got home, I began researching more on my fish tooth to try and pin an ID. My initial idea was that it could be a Hadrodus incisor like what Jared had in his collection based on size and coloration alone. Jared was quick to point out that the morphology differed greatly between my tooth and most incisors. This was a valid hole in the argument and I went back to the drawing board. The tooth was most certainly pycnodont in origin, but the world of pycnodonts is much deeper than most people realize. When examining the edge of the tooth I noticed a characteristic I couldn't come up with a name for until I saw it in one of the papers on Hadrodus Jared had shared. "Papilla-like tubercles" were the things lining the edge, and thankfully the author of the paper offhandedly brought up another genus of pycnodont that shared this trait: Acrotemnus. After some searching, I found a recently published paper by Shimada on a newly discovered specimen of Acrotemnus streckeri from Big Bend in the Ernst Member of the Boquillas Formation. And wouldn't ya know it, Hamm stated that the Ernst Member can be correlated with the Atco Formation (though I should mention a discrepancy in that Shimada places the Ernst Member in the Turonian and not the Coniacian which Hamm asserts the Atco + Ernst to be). The Acrotemnus paper had some high quality images of the dentition of the specimen, and I found the most similarity in size and morphology with the prearticular teeth of their fish. The Shimada paper mentioned that most pycnodonts are small, only reaching about 25 cm in size. To people who are unfamiliar with pycnodonts, these teeth may not look all that crazy, being measured only as 1-2 centimeters . However, scaling the body with the size of the dentition shows that Acrotemnus streckeri reached lengths of at least 1 - 1.3 meters, making it some of the largest pycnodonts to exist at the time! This definitely shattered my preconceived notions about pycnodont fish. Already, the Atco has proven to be one of the most interesting formations in North Texas. This site is a bit of a laborious drive for me, but I'm certain many future adventures will be had and many more fascinating discoveries with it. Thanks for reading!

Hello everyone and first of all thanks for allowing me to have a part on this great forum! My wife and I are from Michigan but took a little vacation to North Carolina. While here we did some fossil hunting and I would love any help in IDing our finds. I will post pictures of them but I am most interested in the knowing the ID of the first two I will share. 1. This tooth has no serrations at all. Looked kind of like great white but the lack of serrations has me wondering. I will defer to the experts

These are from multiple trips between 2022-2023. all from Calvert cliffs, each trip has something unique I would like assistance in identifying so for convenience's sake, I will refer to the items in alphabetical order relative to the numerical trip order. 1A 2B etc. Trip 1 1A pretty sure it is a crocodile tooth, Thecachampsa sp? 1B this is a bone that i found on the beach, im not sure if it's a cetacean atlas or skull fragment. but it's got this weird hole in it on one side. 1C clearly a cetacean vert. probably a juvie dolphin. i think so bc it doesn't have any fused epiphysis. id like to know what part of the spine this would have been on the animal. 1D maybe the wing of a vert? 1E is this anything? or just concretion 1F biggest fossil I've found yet by far! this massive chunk of whale jawbone. I am going to make a separate post in fossil prep to see about the best ways to clean it. 1G maybe a rib? i believe its a bone of some sort. i need to paleobond this one back together. Trip 2 2A definetely a tooth of some sort. not sure if its a croc or a cetacean since the enamel is worn 2B maybe a rib? or vert wing? 2C I think this might be a turtle shell, because its texture is not pronounced enough to be a cookie fragment. 2D maybe a skate osteoderm? 2E 2F 2G Sand tiger shark 2H crab claw with some sort of borehole? any other comments or ideas are as always, appreciated!

Hello all! I am from Michigan but vacationing in Emerald Isle, NC right now. I fossil hunt often in Michigan but North Carolina is brand new for me. I would love to hunt somewhere off the beaten path that is fossil rich either in a creek with gravel, a quarry, or anywhere else that is not super picked over. My main goal is to find a meg but I love finding any fossils really. I am planning a day trip to GMR but if anyone would be willing to share any tips or suggestions for other places (within 2 hours of emerald isle) that are meg tooth hotspots I would greatly appreciate it. If you prefer to PM that would be fine. Thanks in advance!!!

I found these two teeth in Florida. They look like they could be Megalodon, but I’m having trouble identifying them. What are your thoughts??

I have problem with this enigmatic shark tooth. Location- Poland, Zabierzów (Cracow Area) Age- Cretaceous. Turonian Size- 2mm

Hello. I found this shark tooth in South Carolina. It is 2 inches and is serrated on each side. Can my one confirm the species? Thanks!

Hello everyone, I have gotten really into meg diving this last year to the point where I am driving down to Venice from Orlando twice a month to dive for teeth. I have started to look into getting black water diving and I am not really sure where to start. Does anyone have any rivers that are good for black water diving? I have heard talk that people do it in the Peace river and the St. Marys and I didn't know if that is where most people go or if there are other rivers people dive that hold a good amount of teeth. I don't want to sound like the guy who is asking for your super secret spots but I'm just trying to find out where I should start to get into this. If anyone does black water diving and ever needs someone to go with I would be very interested in going with you and I would certainly throw in for gas money. I also have my own boat so we cold take it out also if that is an issue you have. Thank you for any information you can give me, Parker

Hello Everyone, My friends and I are visiting New Orleans this weekend and I was wondering if there are any places nearby that we could find any shark teeth? Thank you you for any help!
