  1. Some winter! Lots of rain, then wind, followed by highs near 80 F, lows in the mid 40s. Beaches were over run (but I saw no cow sharks when (crudely) IDing teeth. Spring fed creek is icy cold water, but trees are coming alive and soon will be sucking up that water. Lots of fossil bone bits (and beach glass) and three cow shark teeth (two standard bottom laterals, with a top tooth between them). The usual sand tiger, smaller ones dug up, and a few tiger shark, and some small gray shark and a mako or two. Nothing special but a storm coming tonight, may help with beach teeth.
  2. Unfortunately my cow shark spot failed me in several trips (only one lower lateral) in three trips plus a few to the beach.. Odd four or five small tiger sharks in the same number of hunts. A friend found a nice 2" yellow mako while hunting near me on a beach; I get broken or midget teeth. Most gray/ requiem teeth from the beach; not as obvious as sand tiger teeth, and with warm weather has been busy out there, all adult collectors (maybe I need to learn computer games?) If nothing, I am pig-headedly persistent and will find more cowshark teeth, even if not the odd ones I'm seeking (each broken one looks to be a "would have been" special tooth. i get a broken small mako and a few tiny ones. Typical
  3. Four trips, two digging, two walking the beach. One cow shark trip was good, the other nothing (?) Beach trips cold and windy, but lots of gray/ requiem and one ugly rootless almost enamel-less mako (about 1 1/4" or 3 cm, the biggest.). Small hemi, angel, and tiger contributing to the little teeth. Four cow shark. Nothing special, or big, but no one else out (the sane people stayed home).
  4. Four trips, most stuff from beach (a lot of digging for three cow shark). I don't find many skate scutes, found 1 1/2. The usual sand tiger (our most common and easily seen even by kids) and a bunch of triangular ones from the beach, plus a small dark mako.

    September 24, 2023

    Yesterday evening we went out to a spot we haven't visited in a while, it started out extremely slow, until we hit on one spot that held a possible whale tooth (link to ID thread at bottom) and from there we started pulling out a lot more teeth, here's what we found, enjoy! nice hastalis, probably 1 1/2 inches great white with some great colors fish jaw Whale tooth?

    Creek trip 3/19/23

    I had a short trip down to a nearby creek yesterday, and though I was only there for about an hour and a half, it had to be one of my best (creek) trips this year! We retrieved our first complete meg from this creek along with two beautiful great whites.We got some very nice sand tiger teeth. We got a nice little horse tooth. And what gets me most excited is my first piece of ivory.Heres all of the days finds.
  7. Found these in a creek in south east Alabama over a year ago, I was looking at them and noticed these look a bit different from the normal sand tiger teeth, any ideas? Thanks!(sorry I see the pictures don't look great, I'm in a bit of a rush)
  8. Great day! Took a break from chasing weird lower cow shark lateral teeth, and went to my usual (old) spots. Not only did I get ~50 teeth, I stumbled across a Cow Shark Symphysial (!, only my third ever) and a cow shark upper tooth. The biggest tooth (root) is only 0.9" or 2.3 cm; i think it is a mako (?). The one that looks like a typical mako has serrations, so I don't know what it is (?) Found one of the biggest drum teeth I've seen, and four angel shark teeth (most broken). Plenty of sand tiger teeth, just like the old days! Fun to be out, beautiful weather for late February. Getting more tolerant of global warming.

    Summerville/Greens Mill Run side trip

    Better late than never right?! I'm finally getting around to sharing my finds from a recent trip up the east coast for work, with a few pitstops along the way! The first two images were from an all day hunt in a creek in Summerville, with Folly Beach Fossils! The third image are my spoils from a solo half a day in GMR... Right by elm street park, because the water was way too high to go further down stream from there, and I didn't have much time! What a great time finding a couple of new species and making a few more friends along the way! I cannot wait to get back up there and hunt again!!!

    Brachycarcharias?

    I found this “sand tiger” tooth in the Miocene Pungo River strata within the Lee Creek mine (Aurora, North Carolina). It does not resemble any other lamniform teeth that I have from the mine, but it does remind me of Brachycarcharias lerechei, an Eocene species. I was thinking it might be reworked. The tooth is 26mm in length, with “wrinkles” on the lingual face @MarcoSr @Al Dente Thoughts?
  11. Some of the stuff from recent trips. I have had a great year for cowshark teeth @Fin Lover ! One particular spot has produced the best, some even intact. My "usual" finds are sand tiger teeth; most of these, except the biggest, have sharp cusps. And another spot produced mako/ great white teeth. (Some glitches with my scanner; not the image I had edited(?)) May append another later. Weather has been great, cool in the morning, warm with low humidity in the afternoons. Finally getting some rain (too late for my garden) and washing out some teeth and other stuff. Fishing has been good, but the catch poor here (lots of small speckled trout; would think it would bode well for next year, but there seems no connection.)
  12. First time fossil hunting and I brought back the teeth, bone and miscellaneous finds dug up from a spot along the South Carolina coast. I would love some help identifying the bigger ones, or anything that is noteworthy. I'm especially eager to get the right ID on Group B. Here are my guesses, but I am very new to this... Group B: 1-3, 7 and 8: Snaggletooth shark? 4: Megalodon (top left broken) 5: Sand tiger? 6: No idea. The curve seems to be part of the tooth shape, not a result of chipping. I can post a close-up of it or the other side. Group A: Baby Shark Teeth 2, 7: Baby sand tiger? 6: Not sure why this one has a copper color to it (my friend I went with found this interesting) 10, 15: Extinct baby great white? 12, 13: Tiger shark? 16: Similar shape to B6, but smaller Group C: Miscellaneous 1&2: Possibly fossilized coconut shell? 3: I'm not sure if this shell is a fossil or just old 4: Semi-transparent with black grains inside - hard to photograph. Maybe nothing interesting. 5. Probably nothing. Tooth shaped but maybe just bone. Group D: Fossilized bone fragments. Anything distinguishable? Thanks so much for taking a look!
  13. Have made several trips, lots of teeth (mostly small and broken), but have done better than usual on cow shark. Nothing particularly dramatic. A few interesting things will post ater for ID. Generally mostly sand tiger per usual (and a few at top left not clear what they are to me). Not as many with cusps, some sites were gravel and shell bit holes; a long rough history of washing in the sand perhaps. Highlights (second) some verts, bunch of angel shark teeth, lots of drum teeth, a few sand tiger parasymphysials, one pretty just over an inch mako, and three cow sharks (been a good year so far for those; mostly I find broken). Last photo is of the smaller stuff. .
  14. Hi There, I just wanted to confirm that I think (?) these are examples of the large Sand Tiger shark from the Chattian. Jaekelotodus trigonalis ? ... This time period is not one I'm yet familiar with. Though, it is in a similar area to where the O. auriculatus I just received was found. Mangystau (Mangyshlak), Kazakhstan The preservation in this area is poor but the teeth are much larger. You can see the cusps have been worn down/away @Al Dente Cheers, Brett
  15. Hello everyone, I recently bought this tooth on the Internet. Unfortunately, I don't know where the tooth came from or what species it is. Since I'm more interested in extant species, I'm not too familiar with fossils. I think it's a sand tiger shark, but unfortunately I don't know which species. So I hope someone of you can help me with the ID Many thanks in advance and best regards from Germany
  16. 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
  17. 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!

    Carcharias sp.

    From the album: North Sulphur River

    This may be an undescribed sand tiger tooth, or C. amonensis? I'm leaving it in the matrix, so may never know. It's about 8 mm.

    Russian Sand Tigers

    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.
