Trying to identify this piece found on beach in Aruba. I’d love to know if anyone knows if it is a shark tooth & if so, what type of shark! Thanks in advance!

Hello! Help please with identification. In my opinion it has some similarity with Hemiscyllium, but I dont know for sure. Length ~ 1,5 mm. Age - Early Eocene. Location- Ukraine. Thanks in advance!

Hi Everyone, I've had this shark tooth fossil for 17+ years now and I would love to know which species it's from. I got it from an American relative who said their dad found it on a beach (I'm pretty sure in Florida). If you think further up close pics are necessary I'm happy to provide that. Thanks for your help in advance Shane

Hello! My name is Gabe, and I am new to TFF, but I have some shark teeth that I have trouble identifying. Unfortunately, I was not the person who discovered these, but I bought them in a "random fossils and gems" bucket in Gatlinburg, TN. I know the items in the bucket does not come just from the local sites, so ultimately they could be from almost anywhere. I apologize that this will not be much help, and also, I apologize if any of these are not considered fossils, and therefore should not be posted here. Additionally, due to the storage limit for photos, I will do multiple parts with more shark teeth; these are the smallest ones. Tooth 1: 1.1cm L, .9cm W, .25cm D Front (Measured) Front Back Right Side^ Left Side^ Top^ Tooth 2: 1.4cm L, 1.3cm W, .33cm DFront (Measured)^ Front Back Right Side^ Left Side^ Top^ Tooth 3: 1.35cm L, 1cm W, .3cm D Front (Measured)^ Front Back Right Side^ Left Side^ Top^ Tooth 4: 1.25cm L, .65cm W, .4cm D Front (Measured) Front Back Right Side^ Left Side^ Top Thank you for looking at these photos, and I appreciate anyone who responds to this post. If you have any questions, I will be happy to try and answer them. Gabe-Paleo_Man450

In late August, I went fossil hunting in Maryland, near the Calvert Cliffs formation, and found this tooth. I am wondering what type if shark this tooth would have come from. It measures around an inch long.

Recently, after going to my favorite fossil store, I aquired a Otodus Obliquus vertebrae. It came from a formation in Morocco, and is approximately 54 million years old, from the pliocene. Otodus is an extinct mackerel shark, related to the far larger O. Megalodon. The fossil is approximately 10.5 centimeters or 4.13 inches. I was wondering how large the shark would be relative to this vertebrae (assuming this was the largest vertebrae from the shark.)

I've been wondering how large teeth from Cretalamna appendiculata-type sharks could get. In their examination/further classification of these sharks, Siversson et al. depict several teeth that are a good deal larger than an inch/25.4 mm, including a first upper anterior of C. borealis that they note may have originally reached 38-40 mm in height (though with a broken tip is shorter than that now). From a marketplace perspective, C. appendiculata type teeth measuring an inch or larger appear somewhat uncommon, though they pop up from time to time. My question for shark teeth experts and collectors on the forum is what's the largest C. appendiculata-type tooth that you know of? Please post photos of any larger teeth in your collections as well. Below are a few large U.S. teeth that I've acquired. From left to right, they are: (1-3) 28.6 mm, 26.3 mm, and 28.0 mm from the Campanian of Russell County, Alabama; (4) 27.9 mm from the Santonian-Campanian of northeast Mississippi; and (5) 28.0 mm from the Maastrichtian of Conway, South Carolina. The tooth on the left would have been even bigger with the tip intact of course!

I have recently found this fossil in north western Kansas (graham co.) I don't know if this is a shark vertebrae/cartilage disk or just a basic fish vertebrae. (Don't mind my bad prep work. I just started peeping fossils recently.)

The niobrara chalk is the best, But what are the ten best creatures from it.

I have been collecting the Aquia formation in several different locations over the course of a few months or so. I haven’t been able to post the finds yet, so I decided that after all this time, I would just group them all into one rather than do a bunch of different posts. The locations I got these from were pg county, and Douglas point. I found a lot of really good stuff, it’s been very productive lately and I’m especially loving the new site in pg county. A lot of good fossils have been coming out of there recently. I am really excited for some of the future trips coming up, but until then, I will show y’all the finds from these locations. PG county (1st location): This little creek has produced a lot of really good finds. Every time I go here however, I always end up finding a broken Otodus. I have never pulled a complete Otodus out of here in all the time I’ve been visiting. Someday it will appear. Here are the photos of all the finds: All the finds grouped together: Two incomplete Otodus, a couple sand tigers/goblin sharks teeth, and some stingray plates are all that was found at this location. A cucullaea gigantea (giant false ark shell) found at this location. Some of the shell was intact as well. Close ups of the bigger sharks teeth: The two Otodus teeth are both broken, with one being heavily worn, and the other having a sheared blade and cusplet. Why I cannot find a complete one here I don’t not know. There are also some sand tiger teeth pictured here that I found as well. Flipped: The broken Otodus to the right is so pretty. Too bad it’s not complete. Smaller sharks / fossil fish teeth: In this photo, there are small sand tiger teeth, a hound shark tooth, and some other smaller species as well. There’s some fish teeth pictured here as well. Smaller fish / shark teeth flipped: I really love the deep black on some of these teeth. I hope to find a bigger one in this color. pg county (second location): Now this place is one of my favorite to go to. It’s got a lot of ground to search, and the fossils that come out of here are in stellar condition. the invertebrate fossils that come out of here preserve extremely well, and the vertebrate material from here is quite abundant as well. Every trip there never leaves me empty handed. In the past I have pulled out multiple Gastropods, a complete Otodus, 3 complete crocodile teeth, large sand tiger teeth, and a whole lot more. I now have some of my best Aquia formation fossils from both of these groups thanks to my recent trips here. The finds are as followed: Vertebrate remains: I have found quite a bit here. These are some of my best vertebrate remains I have ever found from this particular formation. The finds pictured here include a monster of a crocodile jaw, that is one of my favorite finds pictured here. That crocodile would have been massive in size. I measured my largest tooth against its sockets, and it didn’t even compare. The teeth coming out of this croc would probably be 2 inches in length. It’s a really big jaw! I also found a really nicely colored greenish orange sharks tooth from a goblin shark. It’s pretty big as well. The smaller sharks teeth are nice as well. I love the color of some of them. Vertebrate remains close up: The croc jaw is truly the star of the show, but I love all the fossils that come from this place. I will be returning here soon and look forward to collecting here once again. Flipped: The edge of the bone is extremely detailed, and it came right out of the clay as well. It’s like the bone just fell off the crocodile. The teeth that come out of here always have a lot of colors, and can be orange, greenish tint, or white colored. I I’m normally used to blue teeth from the Aquia so it’s cool to get some unique colors out of here. The bone itself also can have purplish tones to it making it stand out, and I have some pictures of the bone color uo close. The preservation from this layer is outstanding and I hope to keep pulling good fossils out of here. Close up of croc jaw: I don’t know if it’s obvious but whenever you look at this bone closely the color is almost a light purple of lavender. It’s a really beautiful color and makes the fossil all the more interesting. Invertebrates (some shark teeth in rocks, and potential Native American activity?): I found some oyster shells, a really nicely detailed small Gastropod. A really large (5 inches length) gastropod, a couple shark teeth, and some rock that looked worked. I’ve been looking for Native American stuff and believe to have found some pottery from here and some large rocks with chucks broken out of them, almost looks intentional to me and not done by the earth. Anyways I’m always keeping my eye out for that kind of stuff. Fossils close up: The two gastropods are my favorite finds from this location. I love how hefty the first one is, and the second one is beautiful. It’s hard to extract fossils from this stone complete as the shells are extremely soft and the matrix is hard to break open with a hammer and chisel. Douglas point: I have found a lot here. I took two trips here, which have been both separated. The first trip gave me a nice fish jaw, an Otodus in superb condition, and a lot more. I found a lot that day. The second trip was a whole lot less finds but found a small croc tooth and a really cool looking paraorthacodus clarkii. Here’s all the finds from this location: First trip: I found a lot this day. A piece of pottery from the old plantation, a huge fish jaw, some nice sand tigers, and a bunch of Otodus including a beautiful sharp 1 1/4 inch Otodus. Closeup: Some of the better stuff found that day. Close up of Otodus: What a stunning tooth! It’s absolutely perfect with very minor blade nicks from feeding. It actually makes this tooth a little cooler that it had been used to eat something. Fish maybe? Crocodile? Turtle? Another shark? Who knows. Otodus flipped: I am in love with this tooth. This is one of my prettier Otodus teeth. Last trip: I didn’t find a bunch this trip. There was absolutely no wave action, the water was still, and there had been no storms. It was way too calm to produce any good finds. I still managed to scrape up a small crocodile tooth, and a paraorthacodus clarkii with broken off cusplets. Some nice sand tigers as well. Here’s all the finds: Not much found that day. here’s a picture of the orthacodus: Broken off cusplets but it’s one of the biggest and most peculiar looking orthacodus I have in my collection. Thank you all for reading! This was a really fun compilation to put together and I cannot wait to get back out there and find more fossils. I’ve done a lot of research and am very excited with what locations I have next in store to visit.

I recently purchased a sharks tooth from florida. I believe it is from the miocene epoch. Although it doesn't look like it in the picture, it has cerrated edges. (don't mind my bad camera)

This is a tooth I found in Northwest Kansas (Graham Co.). It is 100 percent complete. It looks like nothing I have ever seen before. It has cerrated edges which leads me to believe it is Squalicorax Sp. but I am not sure because of its odd and blunt shape.

Hello! Help please to identify this Orectolobid tooth. Height ~ 1,2 mm. Age - Early Eocene. Location - Western Ukraine. Thanks in advance!

Hello all!!! I recently got some micro matrix from the North Sulfur River, Ozan Formation. I think I have properly ID's at least some, but there are quite a few I am uncertain of. I will appreciate any help! Thanks in advance! All are around 1/16- 1/8 inch with maybe a few 3/16ths. The only ones I am for sure of are the following: Pseudocorax granti, but would appreciate confirmation: 1. Scapanorhynchus texanus top row Squalicorax kaupi bottom row 2. I am less confident about my ID of these: 3. And these SEEM like Microcorax crassus but according to the Collectors Guide to Fossil Sharks and Rays by Welton and Farish, they are not found in the Ozan (Campanian), but only in the Cenomanian 4. I think these are Scapanorhynchus texanus but the cusps seem doubled? 5. And now for the ones I REALLY have no idea: 6. A and B 7. C and D - note B, C and D might be Pseudocorax? Now these (A) look like Carcharias sp. A in the Collectors Guide, but again, these are supposed to be from the Cenomanian and not the Campanian (Ozan) 8. 8B - These look exactly like the Odontaspis I found in Missisippi but I can't find any info on them being found in Texas I did find this on Elasmo though: http://www.elasmo.com/genera/cenozoic/sharks/odontaspis.html Two more of what look like Odantaspis 9 C and D

Found in a conglomerate bed of the upper Vaqueros fm. has a weird shape, almost like its been digested? been curious about it for a while. Ventura County, CA

So I got this fossil today and I'm not sure what specie of shark it belongs so i thought might as well post here. I'm new to all this so please excuse my bad post. Also, english isnt my first language so sorry.

Hello everyone, I am new to the forum and love looking through all the neat finds. We frequently go to the beach and love to look for unique finds whether it be shells, sharks teeth, fossils, etc. We also metal detect on occasion that pulls up interesting items sometimes. I mainly joined to help with the identification of some of our finds and to check out what everyone else has found. I will gladly help ID anything I have information for.

Here's an odd one. I think it's a Parotodus that might be the species, P. oligocaenus, which I have read is valid - something to talk to David Ward about. I bought this around the mid-90's as part of a small lot of teeth from the Suwannee River, Florida. I wasn't sure what it was at the time and Parotodus wasn't an in-demand genus like it is now. The dealer thought this and the other teeth washed out of the Ocala Limestone (Late Eocene). I lost track of this tooth and thought I might've traded it somewhere down the line but found it with another tooth from the same site in a zip-lock in a different box. It measures just over 1 1/8 inches. It looks like some Oligocene Parotodus I've seen. @fossilselachian @MarcoSr @isurus90064 @sixgill pete @Al Dente @sagacious @Northern Sharks

HI All We are going to be staying near Orlando for this christmas/new years break. I have convinced my wife to come with us on a fossil hunting trip. She does not swim and will not go in a boat or canoe. I realize we are probably looking at going to the Peace river near Wauchula to hunt. Can anyone suggest where we can go where we can hunt without using a boat? It looks like the Peace river water level is dropping. It doesnt have to be near Wauchula, keeping in mind we are staying near Orlando. We are actually staying in Clermont. Thanks

Hi all, Looking for some help identifying some teeth found in a creek in Monmouth county.

Yesterday, I embarked on my second journey with the Austin Paleo Society to a famous spot: The Wilson Clay Pit. It's the site of a former clay quarry that was used for the production of bricks. Though it is in private hands, the land owners are very kind and allow fossil hunters to collect a diverse range of Pennsylvanian fossils on their property. One of prize finds from the pit is the highly-coveted Petalodus tooth. Some of y'all may remember me wishing to find one on my last trip to the Brownwood area, only to realize we weren't at the right sites to find them. Well, if there was a place to collect beautiful Petalodus teeth, it would be the Wilson Clay Pit. With that in mind, I excitedly set out on a starry night drive. When I arrived, the sun had just beaten me to Brownwood. Temperatures in Central Texas dropped off recently, so we were looking at a frigid day just above freezing. Everyone was covered head to toe in heavy duty winter wear. Nevertheless, optimism was high, so I didn't hear much complaining! When we got to the site, I was blown away by its dramatic terrain. All of the previous quarry work had created huge artificial mounds of gravel and slabs filled with a variety of vibrant colors. In my opinion, it didn't have the beauty of a natural landscape, rather, the inner fossil-hunter in me was simply in awe of the virtually limitless acreage of huntable ground. Exposed randomly throughout was the Harpersville Formation and Saddle Creek Limestone. After @erose gave us a brief introduction to the site, we all disappeared our own ways into the vast, maze-like property. Notice how there's no one else in the pictures? The pit is huge. If it weren't for the greenery, you might think it's Mars. Most people headed off to one side of the entrance or went straight to the back. I was drawn more to the opposing side where there was a huge mound to climb. My goal was to find a spot that hadn't been touched by previous hunters (some mentioned that the Houston club may have been there recently already), so I was trying to get to places a bit more tedious to reach. Crawling up the gravelly incline, I wiped out within the first ten minutes. Luckily, when I turned around, everyone was already gone . From there, things started off a bit slow. I was scanning the ground, picking up anything mildly interesting since it was all new to me. It took a thousand crinoid stems before my eyes locked onto the bright white color of what could be the "porcelain" appearance of enamel. Nope, just bird poop. This cycle repeated five times before I finally found my first undeniable chip of Petalodus! Lots of Petalodus chunks to be had. These are only the ones I decided to keep! I took this to be a sign that virgin ground was finally reached and immediately got to being more thorough in my search. Pretty soon, the tiny teeth bits became more common than the bird poop and my intensity increased accordingly. After a solid 15 minutes of following the cookie crumbs, I was met with a sight that stole my breath. Before me lay a stone with a giant Petalodus perfectly prepped by natural weathering. It was a hundred times better than what I had expected coming into the day. I quickly snapped a photo and got to carefully packaging it in my backpack. Already, my trip was made. An awesome Petalodus specimen. The tooth is about 45 mm across and 54 mm from top to bottom. The day was still young, so I got back up and went to searching. I think my eyes were only attuned to sharky things as those were what I was picking up the most. My bias towards white objects paid off even more as I accumulated a small collection of Deltodus fragments. I like that their white color contrasts nicely with the black Deltodus I found in my last PSoA trip. Halfway through the day, I looped back around to the entrance where I decided it would be best to drop off my prize find, in case I wiped out again later. Because of my vertebrate success from earlier, I set myself to make some invertebrate finds and give balance to my collecting. I found that the purple layer was invertebrate rich and had heard of the possibility for crinoid calyxes, trilobites, conularids, and more. Climbing up and sliding down the purple slopes was blast. There was often something new to reward the effort and my pockets were quickly heavy with brachiopods, crinoid material, and horn corals. This is not edited. The stuff really is this purple. Unfortunately, I wasn't making any out of this world finds on the invertebrate side, so I instead continued my search while also hiking around the entire perimeter of the pit. The eastern border extended pretty far. As I traveled that way, I noticed more and more chert covering the ground. Some had mentioned arrowheads being found on that side of the property, but I didn't see much worked material. As I circled around, I decided to say screw it with the inverts and go back to searching for teeth. I began inspecting rocks of similar appearance to the ones in which I had found teeth before and made a breakthrough. I couldn't believe it when I spotted the crowns of two decently sized Petalodus poking out of two separate boulders. Unfortunately, the limestone was very tough and I knew that getting them out without shattering them would be nearly impossible. My time would be better spent looking for more accessible ones; if there were two that could be found just like that, then surely there were many more nearby. After showing the teeth to Brian, another PSoA member, we both went on a quest to find a perfect specimen that could pop out. As I travelled up the adjacent mound, I did find a decently sized Petalodus, though most of the crown was missing from weathering. It came out in one piece, but I decided to give it away. Not so long after, I followed up with a beautiful smaller tooth that was entirely burnt orange. In my excitement, I forgot to take an in situ pic and immediately began planning a method of attack. Of course, such an awesome find just had to be buried under a thorn bush. Brian was a great help, pulling away the thorny branches so I could get in and make some swings with the hammer and chisel. It took some work, but the durable limestone eventually gave way and the chunk with the tooth came out. After gathering myself, I noticed that some of the root had splintered off. I did manage to locate one piece of it, but the rest was nowhere to be found. Can't win em all, but still happy with it nonetheless. Another beautiful Petalodus. This one is 37 mm wide and 33 mm tall. By then the sun was setting. Most of the group had already gone home, so it was just me, Brian, and Melvin atop the mound. We had some nice discussion, but I think we were all a bit worn out from a day's worth of running around this fossil hunter's paradise. The weather, too, had gotten tired of strangling us with cold, and a final gentle breeze flowed passed the hilltop. God rays poked out from the Westerly clouds to illuminate the distant expanse of greenery I hadn't noticed until then. The moment was nice. After saying our goodbyes, I was a little dejected seeing that I would soon no longer live in Austin and would thus miss out on a lot of future club activities. PSoA has got a really great community, and I'm glad I was there to experience a bit of it firsthand. Luckily, they do have a lot of trips far away from Austin, so I'm sure we will meet again for a future adventure, someday, once they travel close by my neighborhood. Until then, here are some pics of my finds from my latest PSoA field trip: Petalodus ohioensis? teeth Bryozoans, horn corals, and fusunilids Archaeocidarid plate, crinoid arm (Delocrinus) and stem, and a couple of oddities (perhaps conularid or Poterioceras cephalopod fragments?) Straparollus? gastropod and some gastropod from the order Bellerophontida Whole lot of brachiopods. I think bottom center is Meekella. Is that rare? I only found one. Big purple bivalve Shark family photo Thanks for reading!

Found this tooth in ica, Peru. Anyone know what it’s from? From quick research it appears to be a shark, but what kind?
