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!

I recently acquired two Cretaceous lamniform shark teeth that I'm trying to identify. The first one, from Russia, was sold as Cardabiodon sp., but I'm curious if that's correct or if it's something else. The second tooth, from Texas, didn't come with an ID. Thanks in advance for any help you can provide! #1 - Cardabiodon? sp. This tooth is from the Cenomanian of Russia and was found near Fedorovka Village, Tambov Region. The tooth measures 28.51 mm on the slant and 14.91 mm at its widest across the root. #2 - Unidentified This tooth is from the Lake Waco Spillway in Texas, from the Del Rio Formation, which I believe is Albian in age. The tooth measures 15.93 mm on the slant and 11.15 mm at its widest across the root.

Hey all, I've been on the fence about this tooth. It was a beach find (Venice, FL), so I think it is a little damaged and tumbled. Could the root be notched on one side? (The other side looks broken off.) Is the center boring potentially natural? Many 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:

Last weekend a friend and I took our first trip down to Summerville, SC on our own without a guide. I think we did pretty good for our first time scouting and hunting on our own. We can't wait to get back down there!

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

Hello, recently went on a trip to highcliffe beach/Barton on Sea (both have same formations and stretch of beach). I found 11 water-worn shark teeth from the shingle which are attached (I can post more of specific ones if needed) and lots of gastropods directly from the Barton clay, pictures will follow tomorrow if those. The formation is 40M years old. I have some rough ideas for what they may be but need some help Going from left to right starting on the first row: 1&2 I believe to be sand tiger shark of some sort. 3,4,5 and 6 I thought could be Carcharodon Auriculatus. 7 Is part of a ray plate, although very hard to capture in a photo as it is so small. Next row I don't have a clue about really except 1st I think is striatolomata sp. And 4 along (second tiny one) I think is also sand tiger possibly. Particularly curious about the one I posted more photos of individually (⁶th along on row 2) as it has a very circular top, so wondered if this could be an alligator or croc tooth? As I said I can post more of any individual ones and the gastropods tomorrow. Thanks in advance for any help, as I am in full noob mode trying to figure these out :P.

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.

Are these real Megaladon teeth?
Erin36 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I just purchased these sold as Megaladon teeth. I see some repairs I think. The big one I think is in almost perfect condition. The others seem small so not sure if they are Megaladon or another shark fossil? Any help is appreciated.

Please help with an ID for these small teeth found in the Lee Creek spoils pile. Sorry for the poor image quality, but my cell phone does not take good pictures of tiny objects. Both teeth are approx. 5mm wide and 7mm tall
