From the album: Sharks
I ran out of room in the other display, so I split the collection into extinct/extant species. I probably still need another riker! For scale, the big great white tooth is about 2 1/4" slant height. In red are species that are endangered or critically endangered. The only teeth I regret having are the modern Makos, I had gotten them for comparative reasons (both are anterior, left is upper, right is lower). The fossil Mako is actually an I. desori (a big one!), but I included it since it's so morphologically similar to the extant species, and a few people would say they're synonymous. Species included (obviously will grow): Alopias superscilliousus Alopias cf. vulpinus Sphyrna zygaena Sphyrna mokarran Carcharhinus obscurus Carcharhinus plumbeus Carcharhinus brachyurus Carcharhinus falciformis Carcharhinus leucas Carcharodon carcharias Carcharias taurus Galeocerdo cuvier Isurus oxyrhinchus Lamna nasus Negaprion brevirostris Rhincodon cf. typus -
Hit the Aquia Fm at Douglas Point, MD on Sunday and found some beauties. I am really unfamiliar with Paleocene sharks and wondered if anyone wanted to help ID some of these. The one I'm most interested in is the small one on the left pointing outwards. Sorry for the lack of scale - the biggest aren't much longer than a cm. Thanks!

I have been a little bored lately and missing micro matrix searches. It’s been awhile since I’ve gotten to enjoy hunting for tiny shark teeth. I got some more matrix from the Rollins Member of the Mesaverde Formation. My first time through that matrix produced one of my favorite finds, a 1mm Scyliorhinus tooth. This formation doesn’t provide much in the way of complete teeth but it is a fauna that was really quite diverse. The first search was with less matrix but I found enough to want to do it again. This time I have more matrix and in varying states. Some is broken down, some is in small matrix bits and we have a small piece of untouched matrix. It’s a good chance to practice breaking matrix down and learning a broader approach to collecting. The first search of the broken down matrix and first look at the small bits has yielded few complete teeth but a much wider diversity which makes it fascinating. The first Squalicorax, Ptychodus, Lissodus, and Rhinobatos. It also produced an Orectolobiformes that doesn’t appear to be Chiloscyllium. It looks much more similar to Restesia. I am really looking forward to searching more as the breakdown goes forward. I am going to take closer pictures tomorrow but the first time finds are among the teeth in this picture.

My best guess is the black shark tooth is a sand shark and maybe the grey is a great white . . . have no idea what the gold sample is! Any thoughts?

I have taken almost six months off from my favorite fossil adventure - shark tooth hunting. I was a little hunted out after a torrid pace in 6 years that saw me and my wife finding over 1000 Ptychodus teeth and some rare pliosaur and mosasaur teeth during maybe 50 to 100 small outings each year. We even traveled to Wyoming and the Dakotas "to check off some unvisited United States". But, much to her chagrin, I/we got a lot of fossil hunting time in at the expense of other trip priorities. Yes - I was obsessed with Ptychodus. But, I think that I am now a little more even-keeled. During the six-month hiatus, I took the time to pass on some of my local knowledge to help @Jared C. in his Central Texas area fossil adventures. He and his brother found and excavated a partial basal mosasaur skull from somewhere locally. I asked him not to tell me where (I have no idea) because I enjoyed helping him and I didn't want to spoil his enjoyment of the chase. Note to experienced fossil hunters - new eyes often see things in an unconventional way. And, that is a good thing! I try to look for and learn new things every time I hunt the same area. So, in middle February 2022, there we were together for a couple of hours in the creek in one of my favorite outcrops. It wasn't the sunny day, I had hoped for, but most importantly it fit my wife's schedule. She gave me a Christmas gift of monthly fossil hunts with her! Such a gift, even after dragging her through the baby mosquito hatch in South Dakota to find a rainbow colored ammonite! Now, that's love! Not the ammonite! You can find 8 or 9 species of Ptychodus in 30 vertical feet of Eagle Ford and Austin Chalk - Atco outcrop - all at predictable stratigraphic levels along a 400 yard long stretch of creek. I learned that Ptychodus strata marker fossil trick from Shawn Hamm. Here are pictures of a few teeth from this hunting spot from one of my favorite Ptychodus species (occidentalis). One, I found in the February 2022 hunt and another in 2021. The third tooth in early 2019. The first one has a little snail-like curl at the middle of the crown. The second is a rare upper medial file - so, strange in shape and form. They are both 10 mm or less in size, but nearly flawless and unique. Still hoping for another 25 mm+ size P. occidentalis from there but without the smashed off crown top (third one in last two pics). Happy hunting! But, I encourage you to stay even keeled. Don't get too crazy! It's just a pretty rock! But, it still can be amazing!

Here are 8 teeth from Douglas Point, MD. Aquia Formation. Thought I’d get opinions. The first 6 are around 5.25 mm. The last 2 are 2 mm. I have 75 more to go through and decide on ID.

Haven't had much time to go out recently but took off Sunday to search some private beaches near the Potomac River. Was worth the trip! Found alot of small teeth over the 2 hours searching with my lovely lady tooth seeker. Started off with a really good giant white shark tooth 2inches long just laying on the beach. Then walking another 20-30 yards I see this weird looking thick rock just offshore. Wasn't planning on getting it but I had the sand Dipper so I scooped up anyway. Was shocked! My first Meg tooth. It's broken off in the top right corner but I'm assuming it's a juvenile Meg? After about a hour things got really good. The tide was going out and left a little pool of water about 8inches deep on the shore edge with alot of rocks! Bigger the rocks bigger the teeth. So I start scanning. I see what looks like a 3.5inch sharp object. Ends up being a heartbreaker of half a Meg. Dang it!!! But still amazing find. Then something catches my eye 2-3ft away and it's a very nice 2inch white shark tooth. Found 4 other teeth all in rock bed all within 10ft of each other. I'm thrilled! Wish I could have found a full piece 4 inch Meg but something is better than nothing. Best part was just getting outside. Water was freezing though!! The girlfriend found a ton of small teeth, one amazing cow shark tooth, and a ray barb. I did get some not so nice grins over the Meg finds but next time I'm sure she will kick my butt. Over all was the best 2 hours spent in years finding teeth. One Meg, then another Meg, and I believe another 1-2 that are Meg frags. I believe the other 2 inch teeth are giant white shark or maybe makos? Thanks and happy hunting! Just posting some images of the finds below.

Douglas Point was my destination last month, but I really love Matoaka, so I freed up some time to make it out there this past Wednesday. I try to make it out for some fossil hunting trips in the winter months, both for the benefits of less competition and more solitude at the beach, but also for some of the unique scenery. I really enjoy checking out some of the ice formations in winter along the water. There's some really neat looking ones I got some good photos of, along with some of my finds this trip. I made it out there just about at low tide at 8 am. I like to stay for a few hours, and only saw about 4 people, other friendly and interested fossil hunters. Right off the bat, walking around the tide line, I found two medium sized Hemis only about 3 feet apart, which was really encouraging. However, after a couple more hours, I didn't find too much more just sitting at the low tide line. This time last year, I had managed to find both a juvenile megalodon tooth as well as a Thecachampsa croc tooth, so I had high hopes, but really big finds weren't to be this time. Still a great place to be around nature, sit, and reflect. After doing some sifting a little later on though, I did find a nice medium sized C. hastalis tooth, which I don't find too often, so I was pretty happy with that. Overall, I do really enjoy Matoaka. Finds tend to be fewer than going to somewhere like Douglas or Purse, but at Matoaka there is always the promise of a big Hemi or Meg tooth just waiting out there to be found. Happy hunting.

Please help identify these items or help verify if they are even fossils
Maneralization posted a topic in Fossil ID
Hello. I am new here and I have quite a few specimens that I believe to be teeth or claws, that appear to have fossilized from a mineralization or petrification process, but I could certainly be wrong. These have all been collected from SW Missouri. Any help would be greatly appreciated.

Agaleus + Other Jurassic Shark Teeth Wanted
Untitled posted a topic in Member-to-Member Fossil Trades
Hello, everyone! I am in search of Jurassic shark teeth. Primary species I am looking for is Agaleus dorsetensis, an Early Jurassic Galeomorph shark that has been found in Europe, most commonly at Lyme Regis, UK. I prefer teeth with no matrix, no repairs or restoration. Other Jurassic taxa I am looking for include: Palaeocarcharias stromeri Crassodontidanus Notidanoides Phorcynis catulina Palaeoscyllium formosum Corysodon cirinensis I can offer fossil shark teeth of different rarities, depending on which teeth of these you can offer. Some of the more desirable taxa can warrant teeth of high rarity in return. I have everything from deep-sea squaliform material, to many of the desirable Cretaceous lamniform species, and other scarce shark taxa. Please send me a PM if you have any of these teeth, and what species you may be looking for in return! Best Regards Ben -
Hello, So I've very recently learned about bone valley shark teeth, and thinking I might get a nice BV hemipristis serra tooth for my collection. Knowledgable members on this sub have been kind enough to show me examples and inform me that the classic, uniquely identifiable bone valley color is "solid white root + solid dark blade". As I'm still an amateur though, I wanted to ask TFF members to see if these following specimens that I found are indeed distinctively BV hemis, and which one is the nicest example of such? I've posted both lingual and labial surfaces of each. Here they are: 1. Few chips and missing serration, dark blade 2. Bigger chip off, lighter blade 3. Sections of enamel chipped off near the root 4. Lighter blade, a few missing serrations 5. One edge of blade a bit worn, root seems not quite white 6. Enamel a bit light, root not quite white 7. Enamel light, root not quite white Thanks.

Recently I acquired a bulk lot of Moroccan shark teeth after doing some reading and a lot of sorting. I have more questions than identifications. To keep it simple I stuck with the “square rooted teeth for the first round. I’ve come up with five categories 1 two cusplets - Serratalamna? 2 multiple cusplets but small - ? 3 two cusplets - Cretolamna? 4 two cusplets and no or very weak transversal groove - Otudus? 5 strongly reduced cusplets - ? If other pictures are useful let me know.

Just in case you did not read my recent post... Hope everyone is doing well. I miss being in a creek or on the beach, but all in due time. Every night I have been relaxing going through different types of matrix. Last week, in addition to looking through Bakerfield matrix, I also looked through Pungo Formation matrix from Lee Creek. I believe the these are three shark teeth are whale or basking shark teeth. All measurements are in MM. Any feedback (as always) is much appreciated!! 1. Basking shark tooth with the root!! If I am right... wow! If I am wrong.. nothing new and any expertise is much appreciated!! 2. No clue? So pathologica whale shark 3. 100% My favorite shark when I was a kid and my daughter thinks I am a superhero because I have a whale shark tooth Thank you for any feedback and looking at my teeth!

I have a few shark teeth that require second opinions on the IDs. All are East Coast of the US. First up, a Pungo River micro. 4mm or so. This is a familiar tooth form to me as I’ve seen this exact tooth in STH micros. I had put teeth of this exact form in with Cetorhinus teeth because it’s so common in STH micro mix. I could be wrong about the ID on the STH teeth plus Pungo River is different as I believe Cetorhinus teeth are quite rare in that fauna. Both STH and PR have Cetorhinus and Alopias teeth. I believe there is a close familial relationship between those genera so I figured best to get other opinions before labeling this a Basking Shark. I had a very, very small amount of Lee Creek micros to pick through, like half a sandwich bag. The odds of finding a Cetorhinus in that amount of matrix would be astronomical lol It’s probably why I doubt my ID. @siteseer @sharkdoctor @Al Dente @sixgill pete Anyway, here it is. Cetorhinus or Alopias or door #3 ?

I purchased some Ptychodus teeth and I can not determine the exact ID on my own. They are smaller than P. whippeli or P. mortoni teeth I have and bigger than the single P. anonymous tooth I have though that is the species I originally though, and still think these are. They are from the Kamp Ranch section of Eagle Ford in Texas. I consulted a very well put together ID guide here but am still just not sure what I have, other than nice Ptychodus teeth lol Any help would be appreciated.

Hi all. This past Thursday I made it out to Douglas Point (Paleocene, Aquia Formation). I found the usual assortment of sand tiger shark teeth and some goblin shark teeth too. Unfortunately, finding an Otodus in this formation still eludes me. First is a picture of all my finds. What I'd like some ID help with are the vertebrae, the two bone fragments, and the crocodile tooth. The last tooth is an interesting one. Looks like a Hemipristis serra tooth to me, though I didn't think they're found in this formation. I included an in-situ photo with the characteristic Douglas/Purse gravel as proof of location. I know it could have washed up from some other part of the river with a Miocene exposure, but it's in remarkable shape for having bounced around for miles in the river. Any thoughts? Thanks all!

This past Thursday, I made a trip out to Douglas Point along the Potomac. I enjoy going in warm weather like anyone, but going during the winter has its own merits. Cool, crisp air, fewer people, possibly some more unique finds. I was the only one on the beach for just about the whole morning and afternoon. Although a little chilly, the right gear made it no problem at all. The trail down to the beach is a bit run down. Lots of broken and collapsed trees covering the trail. I found quite a few sand tiger teeth. I only keep the larger ones now that I find and leave the small ones for others. About one foot into the water at low tide, I saw a characteristic cone-shaped object rolling around. Sure enough, it turned out to be a crocodile tooth. I've only found one other one at Matoaka beach, so this is probably my favorite find of this trip. My most curious find was the small, pristine Hemipristis tooth. The snaggletooth shark was not found in the Paleocene. It didn't arrive until later and is commonly found in Miocene exposures. On the ID page, it was mentioned by one astute member that the nearest Miocene exposure is downriver, making it unlikely this tooth washed up from another location. The most likely source is apparently another hunter/collector dropping it either accidentally or intentionally. Hopefully, it was an accident, as "salting" is really unnecessary at this location. Unlike some other locations, it's not hard to find at least small teeth at Purse and Douglas. I only keep the bigger, better finds, and leave other small teeth for others to find. I encourage others to do the same. There's almost nothing worse than going to one of these locations with young kids and they get bored and upset because they can't find anything. But I can't agree with "salting". It ruins the integrity of the site. I also found some shark vertebrae and some possible reptile bone fragments. I also found an interesting concretion or maybe some piece of metal that's rolled around in the river for awhile. Never know what you'll find! Overall, a good trip and a great location, even in winter, if you're up for a little adventurous hike through the snow and fallen trees to reach the beach.

Got out on the river yesterday for what turned out to be a productive day. It was a chilly morning so the wetsuit was a necessity. Even if the air temp is warmer the water stays cold throughout the day. I returned to a gravel bed I found earlier in the week and got right down to digging and sifting. Every clean out of the sifter provided a good number of various small shark teeth. Tiger, Sand Tiger, Snaggle Tooth were abundant. A few small partial megs and even a baby Mako made an appearance. Below is a picture of the best of the shark teeth along with an alligator tooth and what I believe is probably a modern pig. left side = Tiger, Sand Tiger, baby Mako and the possible pig. right side = Snaggle tooth, Lemon and Alligator. A couple of close ups of the Alligator: And a couple of close ups of what I think is the pig. If it may be something else please chime in- These finds and the additional bag full of small shark teeth would have been a good day. I was lucky and also came up with a variety of other finds pictured below- Left side- 3 Glyptodont Osteoderms, (the top one from the tail),1 Giant Armadillo Osteoderm. Right side- 5 Turtle/Tortoise leg spurs, 2deer antler bases, 2 gar fish scales, 1 Sting Ray scute, 1 Tilly bone. A couple of close ups of the tail osteoderm- The following large pieces appear to be giant tortoise shell fragments the biggest measures 5.75” x 3.5”. I have at least 5 additional bones I’m working to ID. A possible tiny astragalus, seismoid or maybe magnum, a small medial phalange, a small distal phalange and another possible astragalus or maybe cuboid. I’ll be posting the ones I can’t figure out in the ID section if I hit a dead end. Definitely worth the chilly water on an otherwise perfect day on the river. Looking forward to getting back out there as soon as possible!

Where should I be looking for larger hemipristis serra?
Mara_Masina posted a topic in Questions & Answers
Hello, I've heard that some locations are better than others for finding specific species. My favorite shark teeth to find are those of the snaggletooth shark, so I was wondering if anyone knows where I might be able to focus my hunting in order to find the serrations of my dreams! I live in PA, but am willing to drive as far as Virginia if I have time and money. So far I've found baby H. serra teeth at Matoaka, but as I'm a new fossil hunter I haven't had a chance to check out other sites yet. Any recommendations? Thanks! -
I have 2 small selections of shark teeth that I recently acquired in a collection that I had purchased. These teeth are supposed to have been collected in North Dakota and South Dakota. The first selection was collected on 4-3-1986 in Moffit, North Dakota in the Cannonball Formation, which was referenced by the collector as being Paleocene (58 MYO). The next selection was collected in Edgemont, South Dakota from the Late Cretaceous, Green Horn Formation. Any help on these would be appreciated. Thanks

Hi all! Answering @jpc's question about the site's accessibility in winter and if we actually dig under snow. Yes, we do! (something must be not right in the head). Today we tried the dig at -1C'. Had to make a pretty big hole too (the deepest I've seen there). No big teeth found, hopes for the micro-matrix.
