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.

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, I am a real novice here. I was given several sharks teeth collected on northeast Florida beaches. I am trying to identify them to create a small 'show and tell' for beach goers to be able to ID the teeth they find on the beach. I am now totally confused as some say they are Mako as there are no nibs but there are several examples of Sand Tiger Sharks that have no nibs. I found this forum and am hoping you can help. Also I have no idea what the piece in the middle is. I am assuming it is a broken piece from maybe Tiger Shark? Thanks from a Novice trying my best. Suki2

Got to the beach early this morning and had the place to myself with a great gravel line to search. Got a nice handful of teeth including at 2.23” damaged otodus, a 1.42” otodus, and a 1.14” croc tooth.

Found my first two shark teeth. The first one was sticking right out of the clay, staring right at me. The other I found raking through some gravel. Both are goblin sharks, I think.

I recently received some micro matrix from @thelivingdead531. Again thank you so much, it is an awesome gift! But I have been trying to ID the shark teeth and can't figure out what any of them for sure are. I would really appreciate any help. Also sorry about the quality of the pics. I may be able to take better pictures, but only if I need to.

Yesterday I scouted Calvert Cliffs Beach to see if my friends would be able to join me on a fossil hunt there. As this was only my third lifetime hunt, I'd only been to Matoaka prior, and wanted to see if the path to the Calvert Beach was accessible enough for a friend using a cane and someone more out of shape than I am. That said, I'm not fit myself, so the 3.6-mile hike to and from the beach was not easy. However, it was gorgeous! As many people will tell you online, the cliffs at Calvert Beach are not legally accessible; the state park service has closed off access to them due to frequent landslides and therefore little beach space left beneath them to evade a fall. The cliffs there are taller than at Matoaka, making them even more dangerous, and the tide comes in closer to the beach. The remaining fossil hunting space is thus rather limited for hunting, but if you're dedicated and go during the off-season, I'm sure your luck will be better than mine! I was in the water from about 11-3, sifting in the tidal line of shell material and along sunken trees that may have trapped fossils. Attached are a couple photos of my tooth finds, and a picture of the cliff area too. Feel free to ID the teeth; I'm not great at it yet, especially when they're small! I was surprised by the tan tooth since most teeth I've found thus far have been black. Also not entirely sure what the curved tooth came from, though my guesses were either a H. serra symphyseal or a tooth from a sand tiger shark. Overall, I think I like Matoaka better, but it's hard to say from just one visit. Going to take my friends back to Matoaka or to a new location next weekend. I'll scout out Flag Ponds in December I think, then I've got a fossil club trip in January. Really really really having fun!

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! -
It has been a long time since I’ve gone out, it was nice to have the place to myself. Not everything shown, but a variety of things.

Help needed in fossil sharks ID - part 2 (Upper Paleocene of Chile)
terminatordiego posted a topic in Fossil ID
Hello to all of you guys, a couple of weeks before i asked for help in relation with some shark teeth, and the help indeed was very nice! A couple days before i was back in field trip and found some more teeth from the same strata, and would need your help for the correct ID (hopefully at species or genus level), you guys are awesome!!! Here´s the list of the fossils (each step of the ruler is 2mm): 1) A tiny tooth with very small roots and 3 denticles, the central and main one is triangular and very oblicuous 2) A tooth with very triangular cusplets and with small and shorts ridges in the base of the main denticle (wich is slightly curved), the roots are slightly asymmetrical 3) A half of tooth with triangular cusplets and with a slight triangular depression in the base of the main denticle (wich is slightly curved) 4) A (i think so) stingray tail fossill 5) A tooth that i dont know what could be (the tip is very smooth and the roots have a wood-like texture) 6) A tooth that i think is from Premontreia subulidens, but im not 100% sure 7) Something that i dont know what it is, looks like some kind of skin or membrane 8) A tooth similar in color and root texture that number 5, but with only 1 denticle 9) A tooth with very triangular cusplets and low developed roots 10) A tooth with maybe similar look about Carcharias teretidens? but with slightly longer lateral denticles 11) A tooth with aparently only one denticle, and asymmetrical roots (the rightest part of the right root is easly confused with the sandstone matrix) 12) A tooth with two denticles, striae in the lingual face, triangular depression in the base of the main denticle and the base of the crown is much more prominent that the diameter of the main denticle, might be reworked because is from a level stratigraphically higher. Finally, as a bonus track, here it is a vert. that i found in the same field trip:

After going several weeks without fossil hunting, due to weather, schedule, etc., I finally made it out to Douglas Point (Paleocene, Aquia Formation) in Maryland this morning on a very pretty, cool autumn day. My first fossil find of the day was a small piece of ratfish plate. Below is my first shark tooth of the day (a sand tiger, like the vast majority of teeth found here). By the standards of this site, the quantity of shark teeth was low today, but they were in better than average shape, which isn't a bad trade off. Many appeared to be fresh out of the matrix. Finding Otodus obliquus teeth never gets old! This tooth has some tip wear, but is in much better shape than what I expected when I first saw it poking out of the sand. It's about an inch long. The Paralbula marylandica tooth plate below is the second that I've found -- today's wasn't as nice as my first one, but I was still pretty happy to find it. The Potomac River was choppy and silty today, and, as a result, I didn't have as much luck hunting the water's edge as I sometimes do. Luckily, the tides were low, so there was still exposed beach to peruse. Here's another Otodus in the gravels--smaller than the earlier one. The croc tooth below is a little beat up, but at an inch and a half long, it's the second largest that I've found. The shark teeth were all on the smaller side today. The largest I found is below and measures 1 and 3/16 inches long. Hopefully I won't have such a long break before my next fossil hunt. Thanks for looking!

I visited my favorite shark tooth site just north of the Lake of Constance again recently and just wanted to show off a few finds. If anyone notices that I've made any mistakes with my ids then please let me know. Araloselachus cuspidatus The next two I would call Carcharodon (Cosmopolotidus) hastalis, although I know that some still lump these under Isurus. Carcharhinus priscus And the next two I've identified as Odontaspis molassica.

Teeth from Ernst Quarry exhibit phosphorescence under long wave uv light (short video)
Kurt Komoda posted a topic in General Fossil Discussion
Hello, all! I see that there are already a few threads concerning the fluorescent or phosphorescent properties of some fossil, but I thought I'd share a video I took today. I just received a Convoy C8+ long wave 365nm UV flashlight, and so, naturally, I was going around the apartment to see just how disgusting my kitchen and bathroom look when revealed under long wave UV light, but also to take a look at the various rocks and fossils I've collected over the years. I was surprised to find that the teeth from Ernst Quarry, in Bakersfield, all fluoresce a light orange color- like cantaloupe- but even more surprised to see that they glowed briefly after removing the UV light. The video does not show the orange fluorescence- I don't know much about this, but it was just quickly shot with an iPhone 11 and would probably need some sort of lens filter to display what I saw- and the brief flare up you see when removing the UV light is just the iPhone trying to adjust for the change in lighting. I dunno, I thought this was pretty neat. I have a short wave UV field lamp on order, and that will produce different results, as a much lower amount of minerals fluoresce under long wave. What mineral are the Bakersfield teeth comprised of? 818431889_bakersfieldteethconvoyc8test.mp4- 6 replies

Taken with my new microscope camera. The first three pictures will be of crocodile teeth from the Hell Creek formation of Montana and are from the Cretaceous period. All are taken at 20x to show a lot of detail. First photo: Borealosuchus Sternbergi is 4.5 mm long. Second photo: Champosaurus sp. is 3 mm long. Third photo: Brachychampsa montana

I recently purchased some more Moroccan fossils, including several shark teeth...I tried IDing them on my own, here are my guesses (scale is in inches; 1 inch = 2.5 cm), am I close? I don’t have much experience IDing Eocene teeth, so I’m not sure. Thanks!!! 1. Otodus obliquus 2. Cretolamna appendiculata 3. Cretolamna aschersoni 4. Striatolamia macrota 5. Jaekelotodus spp. 6. Brachycarcharias atlasi 7. Tooth I have no idea on (had cusps but they broke off) 8. Jaw bone section I have no idea on 9. Fossil I have no idea on

Hello and thank you for letting me join your forum. My name is Lindsey and today my family went to Big Brook in NJ for the first time, looking for some shark teeth. We found some interesting things and we've got no idea where to even start with identifying the things we bought home. Can you please point me in the right direction? Thank you in advance for your help and I hope you're all having a great week. Lindsey.

An assortment of interesting finds from our hunt today. This was in the late cretaceous Ozan formation (also called the Lower Taylor Marl, I believe) around the Austin area, in central Texas. I'd like confirmation or correction on some ID's 1) I'm thinking Mosasaur tooth for this one, but since it's small enough to maybe be fish, I'm checking anyway. If measurements end up being important for any of these, I can provide them. 2.) I'm thinking Cretolamna for this shark tooth, but it looks like the cusps have two peaks, which is throwing me off. Any thoughts? 3.) A very unusual ptychodus. It looks like there was a dome that was worn flat, but that would imply then that this is a Ptychodus whipplei, which is supposedly quite unlikely around Austin. @LSCHNELLE, any thoughts? 4.) I'm fairly positive on this one being some species of Cretolamna, but since I've never seen Cretolamna in this area before, I'm just making doubly sure. This one is about the size of a finger nail.

While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.
