Hi, I recenty acquired a bulk of shark teeth found on the beaches of Cadzand, The Netherlands. I think there are around 200 - 300 shark, ray and fish teeth in the bag ranging in age from the Eocene up to the Plio/Pleistocene. A large chunk of the teeth are common species like C. hastalis, Brachycarcharias lerichei & Striatolamia macrota teeth. But there are a few I am not sure about and some I don't even a clue about, so I was hoping some people here might help me out confirm my ID. Thank you in advance! All the ray teeth in the bunch Most of the cowshark teeth in the bunch, I think all of these might be Notorynchus primigenius from the miocene & pliocene Tooth 1: 3 teeth which I believe these are upper jaw teeth of Notorynchus primigenius Tooth 2: A cowshark that looks a little different than the rest, might this be a Hexanchus griseus tooth? (Miocene/Pliocene) Tooth 3: The largest tooth of the bunch, due to it's size I am not really sure to which species it might belong, although I believe it might be a large Sand Tiger tooth. Is it an Araloselachus vorax or do Striatolamia macrota & Isurolamna affinis get this big? Tooth 4: a small tooth with large cusps, only one like it in the bunch, the preservation typical of the eocene teeth from this location so I am guessing it is Eocene in age. But I don't really have a clue for the ID Tooth 5: Galeocerdo sp? Physogaleus secundus? Galeorhinus sp? Tooth 6: I am leaning towards either Anomotodon novus or Sylvestrilamia teretidens Tooth 7: Galeocerdo sp. or Physogaleus secundus Tooth 8: Odontaspis winkleri Tooth 9: worn Physogaleus secundus Tooth 10: Physogaleus secundus? Galeorhinus sp? Tooth 11: Abdounia recticona Tooth 12: Brachycarcharias lerichei Tooth 13: Physogaleus secundus or an Abdounia sp? Tooth 14: Physogaleus secundus? Galeorhinus sp? Tooth 15: I am pretty convinced this is an Eotrigonodon serratus tooth

Hi all, I'm looking for photos or good illustrations of dentitions from a few different sharks from the Paleocene and Eocene to help improve my recognition and to learn better how their teeth varied across the jaw. These could be natural/associated sets or artificial/constructed ones. The sharks I'm looking for are: Jaekelotodus robustus Palaeohypotodus rutoti Brachycarcharias lerichei Isurolamna inflata Can anyone point me toward resources for any of these? If you know of dentitions from different species within these genera, those would be helpful as well. Thanks!

I purchased some shark teeth recently, all or most of which appear to be sand tigers, from Russia and am hoping some folks on here might be able to help me identify them. The information from the seller, who is in Russia but didn't collect these himself, is that these are Cretaceous teeth found in chalk deposits on the banks of the Don River, near Kalach-on-Don, Volgograd region, Russia. He doesn't have any more info or know the exact geologic layer. I haven't been able to find much information from searching online, but using the app Rockd, it does appear that the geology in the area around Kalach-on-Don is Late Cretaceous (see composite screenshots from the app below). Many of the teeth themselves also have remnant white chalky matrix on them and some have what appear to be calcite crystals on them. If anyone here knows more about the geology/stratigraphy of the area that you could share with me, that would be great! Below are photos of the teeth. While the info above checks out, I have some suspicion that these teeth might be younger than Cretaceous in age. I may well be wrong about that, though, and would be happy to know either way if you think these look like Cretaceous teeth or if you think they're from a more recent time period. These are nice looking teeth that were reasonably priced, and I don't mind if they're younger; I'm just interested in trying to identify them. I've tried to organize the teeth in the photos below into groups with similar characteristics. Please let me know if any additional photos would be helpful, and thanks in advance for any help you can provide! Group 1: These all have lingual striations, except for the tooth on the far right, though that one's more worn and may have had them originally. The tooth fourth from the left/third from the right has very different coloration than all of the other teeth I acquired and reminds me of the coloration of teeth I've seen from Kazakhstan (perhaps it was accidentally mixed in?). You can't necessarily tell from the photos, but these all have very small lateral cusplets/nubs, one on each side. Here are additional views on the leftmost tooth above, which is generally representative of the others. One reason I question whether these are Cretaceous in age is the striations on these remind me more of Striatolamia sp. teeth I've seen from the Paleocene and Eocene than Scapanorhynchus sp. teeth from the Cretaceous, which in my albeit limited experience have deeper/more prominent striations. The striations on these teeth also do not appear to extend onto the roots. Group 2: These teeth are also lightly striated on the lingual side, which you can see more clearly in the second set of photos below detailing the leftmost tooth. These all have one lateral cusplet on each side of the cusp (more rounded on the two teeth on the right). My guess is these are the same species as the ones above, just different tooth positions. The tooth on the left in particular does remind of Scapanorhynchus sp. Here are more detailed views of the tooth on the left: Group 3: The teeth below all lack striations; the preservation is quite good, so I don't think they ever had them. These teeth have fairly large lingual root protuberances. The first three teeth each have one sharp, but small lateral cusplet on each side. The two teeth on the right both have two lateral cusplets on each side. Here are some more detailed photos of the leftmost tooth: And here are some closer photos of the two teeth on the right, which have two lateral cusplets on each side: Group 4: The two teeth below also lack striations and have one pointy cusplet on each side of their cusps (one of the cusplets is broken on the left tooth). I've separated these two out from the teeth above as the lingual protuberances aren't as large/prominent. Group 5: These are somewhat smaller teeth that may be from the same species as teeth above. All three lack striations. The one in the middle has two cusplets on each side while the other two each have only one. Group 6: These two teeth have more u-shaped roots and narrower cusps than the ones above. They lack striations and have one cusplet on each side of the cusp (though some are broken). Group 7: This tooth has more triangular cusplets than the ones above and a more angular root. It lacks striations. Group 8: The final tooth is a bit worn, but reminds me of the Cretaceous thresher, Paranomotodon sp.

I've wanted to put together an artificial tooth set of Striatolamia striata from the Aquia Formation in Maryland for a while given the abundance of that species in the formation. Until recently, though, I was missing a lot of the less commonly collected tooth positions--extreme posteriors, intermediates, and first lower anteriors. After searching through several gallons of Potomac River gravels over the last couple of months, I finally filled in the gaps. I put together the tooth set below a few days ago and just finished mounting them in a riker box I received in the mail yesterday. I used the Striatolamia macrota artificial tooth set on elasmo.com as my guide. I'm sure some of the teeth in my reconstruction are out of place, including some of the upper or lower teeth possibly being from the opposite jaw instead. I couldn't properly size match the intermediates and first lower anteriors, but can always swap in replacements if I find them. One of the extreme posteriors is also reversed in the display (labial side showing rather than lingual like the rest) as I'm still missing a tooth from that position. Overall, I'm quite pleased with the result. This is my first artificial tooth set, and it was a fun project that taught me a lot about tooth positions! Here's the full tooth set -- the largest teeth in the display are just over an inch long: Left and right sides: Quadrants: The final riker display:

I went out on a fossil hunt last Thursday to one of the streams I like to hunt at. It was only around 28 degrees F when I arrived so I didn't have the highest hopes. I ended up having my best day both quality and quantity wise! I found my first New Jersey hemi as well as my first tiger shark tooth. Also found a really nice sized sand tiger as well as one that would have been a monster if it was whole. Hope you guys enjoy!!

I am having trouble identifying Sand Tiger teeth. Any help on the species of these? Maybe Striatolamia?

Is this a sand tiger tooth? Found in the Calvert formation

I have a tooth here that I'm not sure on - torn between Sand Tiger and Goblin. It's around 1 1/4". It's from Florida.

Slipped out to the wooded creek. Children(?) have been busy hunting, they dig big holes near the creek bed? Maybe they know what they are doing. I was hoping some spots would yield cow shark teeth, but the kids have been busy in those areas. Guess being out of school so long has them bored, or more likely their mothers want them out of the house. No one was out today. Most areas I hunted were full of gravel and I found lots of broken stuff (not shown), nothing of size. I found a few tiny teeth which might be sand tiger symphyseal teeth; the roots look right , but they are smaller than usual? A few imperfect angel, one tiger (rare for this spot), and the majority sand tiger spikes. A few Tilly bones, vertebrae and some elongated curved teeth or bones. I see the poison ivy coming out everywhere! Spring peepers are abundant.

Hello. Does anyone know the species of this sand tiger shark tooth? It is from Florida and is 0.8 inches (2 cm) long. Thanks.

I’m trying to ID the tooth at the center of this spectrum. To its’ left, Sand Tigers. To its’ right, makos. But the specimen in the middle is... a bit of both?

I thought it would be fun and possibly helpful to other collectors to discuss the results of my first foray into the world of micro fossil exploration. I had purchased some quantities of micro matrix from two different formations and they provided vastly different experiences for me as a collector. I got a vial of micro fossils from the Neva formation which is from Kansas and is Permian. This stuff really proved to be quite a challenge and was not ideal to start with. These are TINY fossils and I was not equipped to handle such small fossils. Identifying the shark material was challenging but not nearly as challenging as just handling them. My first attempt to put a fossils on a slide resulted in me crushing a tiny partial Cladodont tooth. I was not happy with myself but it was a very teachable and humbling moment as I did at work in front of young co-worker who has developed into quite the shark fanatic. Once I figured out what NOT to do with the small fossils, I did find a groove and was able to find some interesting material for our display. I found a few shark denticles ( I think they are anyway lol), a possible spine, and a few partial teeth including one that looks similar to an unpublished species of Cladodont shark called Maiseyodus. There was not a lot of shark material and it was hard to work with but I plan on picking up another vial. I will not go through until I have better equipment though but I would like to continue the explore it. The goal was too add some Permian shark material from a marine environment to contrast the freshwater Permian stuff we had. In that sense, we accomplished our goal and I did really learn quite a lot so it was a positive result but one with plenty of bumps in the road lol The other micros were from the Cretacoeus Mesaverde formation and was Colorado. This was much easier to work with as far as size goes but there was much more actual matrix to deal with. I was also more familiar with the fauna and I had a much better idea of what to be on the look out for. It did not take long to find a few shark teeth. I opened the vial, dumped it on the tray and right away saw some partial teeth I could recognize. A few Hybodont partials were apparent very quickly as were some partial Sand Tiger teeth. There was also an interesting partial that I have not posted yet but might be a Cretalamna. I also found a few fossils that I think are ray dermal denticles. The really interesting stuff was found when I started searching the bits of matrix and the smaller fossils. Three little fossils absolutely made this a grand slam for me. I found what looks to be a Chiloscyllium tooth. It is fantastic shape and sits on top of a little piece of matrix really nicely. My ID looks to be okay as I did post here on the forum. I was really thrilled to find such a nice tooth. Another was posted on the forum and though I have some work to do to cement the ID, it MAY be a Cat Shark tooth which is one I have been searching for. Separating it from the matrix makes me nervous but I am practicing before I do it. I am really hoping it does turn out to be what I think it is but either way it was a fascinating find and thanks to some awesome TFF members led to a far better understanding of cat shark fossils. The third has not been posted yet as I need to take a closer look at it but when I first saw it, I thought it was a Rhinobatos which was another one I had been actively looking for. I got excited, put in a gem jar and put it in the display but I will take a better look this week. There were some interesting non-shark fossils too that I will go through at some point and quite a bit of poo as well lol I consider this to have been a complete success. We added some new sharks to the display and succeeded in furthering the diversity of sharks we can talk about. I need to get some equipment for exploring micro fossils at home and I need to work on the handling of the fossils. I need to learn how to separate small fossils from bits of matrix and I can always stand to sharpen my ID skills but this is a pretty important development for us. With some recent family events and two college aged kids depending on me the fossil acquisitions will slow down considerably. I can not buy a lot going forward so this is a fantastic and inexpensive way to continue to explore fossils, particularly Mesozoic sharks. A little bit of money spent on some matrix will yield fossils we can use. I do not live in an area where there is much fossil hunting to be done so this is also a way to self collect some material which is really satisfying. It has also been a great thing to have during my fathers illness and death as it kept me busy and my mind sharp. I can see a new addiction forming and it is a good one to have. In addition to adding some more from both of the above formations, I am going to pick up some Atco stuff and Kamp Ranch matrix too in the near future. That will keep me busy and I am sure we can add some more interesting fossils. This micro newbie is going to work on becoming a micro not-so-newbie lol I will post some pictures in the comment section.

Needed to get out and get some exercise. Relatively cool and dark in the morning, the full foliage shade was nice, surprisingly little water in the creek. I worked one spot hard, found a few partial ecphora, lots of sand tiger teeth, a few angel and drum teeth. A bonito nose a Tilly bone and what probably was once a bonito nose. One three pointed cowshark tooth which I lost when I fell. The highlight was a nice hemipristis (don't find many of those or tiger or mako in this site. And no megs). Bits and pieces drying to go through later.

Hi all, I recently went on a trip to Brownie's Beach in Maryland in search of Hemies, and I came home with some pretty good little teeth and a few decent sized ones. However, there was one tooth that I found I could not identify. I am not really sure what shark it belongs to, it sort of resembles a sand tiger but the root is very robust and thick. Im more or less lost as to what it could be. Wishful thinking, but I thought it might be a baby megatooth shark or a mako or something along the lines of that. Its a long shot, but I thouht i would ask to see if anyone else could Identify it, haha!

Hi so I have been hunting my favorite spot recently, and ever since I first came to this spot I have noticed a good amount of sand tiger teeth popping up, but only in this 10 foot radius. Is it possible that all of these teeth are from the same shark. They all range in similar size and I have only ever found them in this one spot. for every nice one i have pictured. I found 10 more broken ones just missing the roots.

Made two back-to-back trips to the beach, the first trip had too much surf, the second too high a tide. We had a wind storm from the north and I expected stuff on the beach (but a quick glance at the tide lines left on the beach revealed nothing but shells.) First day didn't find much, surf was strong and I lost three in the crashing waves. It was warm out, and i tired of chasing the little teeth. Today was better results-wise. Much cooler and a manageable dropping tide. Walked up and down the beach picking up the occasional tooth (always amazes me that you can find teeth every pass, must be uncovered in the wash, which wasn't moving them today). Good day for makos-- three, one inch long and one or two smaller ones. The shell line in the wash was much thinner than usual, maybe made the teeth easier to see? The shrimp coprolites were deeper in the water than the teeth.

1. Hemipristis serra: One of my first teeth of the day, found in the water. Small, but nice colors and perfect serrations. 2. Carcharias cuspidata: Flawless sand tiger. Symmetrical and super sharp, with both double cusplets intact. 3. Galeocerdo aduncus: Gorgeous tiger, almost looks like a G. cuvier because of size. Very nice root to crown contrast. 4. Odontocete tooth: Little porpoise/dolphin tooth with a long, thick root. In very good condition. 5. Ecphora sp.: A very nice small Ecphora, nearly complete, just missing the white part at the top. Rare to find more than a fragment of these at Brownies. Cast your votes! The poll will end in three days, on April 4th at 3:00 p. m. EST. Hoppe hunting!

Hi there folks, I recently received this lot as gift, but it came with no ID. Is it possible to get an ID from this pic? They are all from Morroco. Thanks in advance.

Tried to get out before the ice storm in search of cowshark teeth (found none and hunted hard). Lots of small sand tiger teeth, including a crooked one and a symphyseal, and lots of split teeth. Lots of drum teeth, (the dull side is more interesting than the glossy side). Four angel teeth that stand up on their triangular base, two whose root is damaged. Two or three mako (broken). Lots of small triangular teeth (dusky, bull, gray? not sure what all they are). Lots of batoid/ skate teeth, but no stingers or denticles. One whole vert and a small disc echinoid. Lots ofsmall 'whale bone' and bits to go through. Not what I was after, but quantity if not quality was good.

(I will now be using the poll format, so you can actually click your favorite and the poll will keep track of the votes) 1. Carcharocles chubutensis: MY FIRST MEGATOOTH! A bit of damage near the root and a missing bourlette, but a gorgeous tooth nonetheless. The serrations are absolutely killer. It’s about 1 ¾ inches. Colors completely changed when it dried. I. Am. Ecstatic. 2. Carcharias cuspidata: Very large sand tiger with a beautiful hooked double cusp on one shoulder. Excellent preservation, and certainly a necklace quality tooth. 3. Notorynchus primigenius: A perfect little cow shark tooth. Found in the cove within my first five minutes of collecting. Not very big, but in fantastic condition. 4. Isurus desori: Incredible little mako. It is absolutely pristine, and still sharp enough to cut you. Has that beautiful Brownies blue coloration on the enamel. 5. Carcharocles sp.: Oh, what could have been...this is the tip to what was probably a huge Megalodon tooth. Based on the thickness of the tooth, it would have been much larger than the meg that I found. Still a great find! The tip of a monster.

So to make up for the rain yesterday i walked all day today. I went sharks tooth hunting in the morning and found a huge sand tiger and a nice posterior meg, then a buddy of mine who lives down south was nice enough to ask me if I wanted to hunt down his way. So i scrambled off the beach and headed south. Well I was lucky enough to find a bunch of my FAVORITE fossil the ecphora!!! I was also able to collect a bunch of shell for mom not to shabby!!!

Bear with me on this trip report, as I'm uploading photos from various devices and attempting to tell a non-boring tale. This past Sunday, 13 May, I went on a fossil hunting trip ALONE for Mother's Day (best Mother's Day ever)! This meant that I could be out as long as I wanted to be, no one to rush me or complain or tell me they have to go to the bathroom a million times. I had an amazing trip, and was very successful in my finds! I've been to Walton twice before and was not nearly as successful. So here we go, I left my house around 11:30am and arrived at Walton at 1pm. The high tide was at around noon, so it was just starting to go out, which I figured would be good for getting first dibs. The weather said it was supposed to be overcast and rain, thankfully it didn't rain on me, and the sun ended up coming out for a very nice day.
