  3. Hi everyone! I recently acquired some dolphin & shark teeth, but they weren't ID'd so I was wondering if some of you might be able to help me out if possible. The first are a set of small dolphin teeth found in Hoevenen, Antwerp in Belgium (Miocene, 15 - 10 mya) And I was wondering if they could be ID'd to down to genus? I've read Eurhinodelphis is a common find and that there are quite a few more named and unnamed species to be found there. The other fossils that I hoped to be ID'd are 5 tiny shark teeth from Oosterzele (Lede formation), Belgium (Eocenen, Lutetian, approx. 44 million years old) I've searched this website as they has a database with I believe all the species found there, but I am not confident and skilled enough to ID them properly. http://users.skynet.be/belgiansharkteeth/Lede formation/Oosterzele set.html My best guesses are that the first 3 teeth belong to the same species and the most common at Oosterzele, which are worn down Otodus auriculatus teeth. As for the other teeth I don't really know, so I really would appreciate some help and input. Thanks in advance!

  5. Cretolamna sp?

    Hello all, I purchased two small Moroccan shark teeth and would like to nail down their species. I think they are either Cretolamna appendiculata or small Otodus obliquus teeth. Please let me know what you think.
  6. Am asking obo a friend of mine. I personally have no interest in this item for myself. But thought I would ask here anyway as I couldn't give him an answer. Is the tooth genuine? Is the ID correct? This is the only photo he has sent me.
  7. I have detailed our shark education program in previous posts but I forgot the best part. Fossils on Wheels has around 350-400 shark teeth that will be given away to kids. All of these come from donations. My son and I have donated around half and the rest have come from donors on TFF, who we have thanked in previous posts. These are really my favorite fossils because they serve a higher purpose. Getting kids interested in science, natural history, fossils and of course, SHARKS !!! I write a lot in these posts but the core of what we do is summarized above. This is fun and we are feel lucky to be doing this. The donations from TFF members are allowing us to do this and the kids will know it. Thanks to donations of marine invertebrate fossils, these teeth are going to become fossil starter kits with other fossils mixed in. The pictured below are some of the fossils. Some STH mako teeth and about 100 Squalicorax teeth are not in the picture because they are in my laundry room at the moment. Tomorrow, I start bagging these and putting together information cards so I wll know exactly how many fossil start kits we will have in a day or two. We have a nice mix Moroccan Squalicorax, Sand Tiger teeth and Otodus teeth, a significant number of STH mako teeth, teeth from a few smaller STH shark species, a few Ptychodus, and a few Goblin Shark teeth. We are trying to make sure we give away teeth from species we cover in the presentation. THANK YOU FOSSIL FORUM MEMBERS for helping us make this happen
  8. Maryland Paleocene 2/17/19

    Headed out to the potomac this morning and man was it nice out. Hit low tide and made my way to the cliffs, which all fallen right now btw. Found some nice sand tigers today’s and some smaller beaten otodus. Highlights of the day were a nice little croc tooth and a croc vert which is a first for me. I don’t seem to find much bone in the Aquia formation.
  9. Hey all! This week my colleagues and I published a paper we spent most of the last decade sweating over. It is an exhaustive report of all known late Miocene-Pleistocene records of teeth of Otodus (aka Carcharocles) megalodon teeth from the west coast in an attempt to estimate the date at which O megalodon went extinct. Aside from some conspiracy theorists who will wait until they die and not see a live 'meg', we all know it's not living today as there is not a shred of positive evidence indicating its existence. We know it's around in the Miocene, and the early Pliocene. Did it survive into the Pleistocene? End of the Pliocene? or become extinct sometime earlier? These questions require serious thought because it has direct implications for whether or not O. megalodon went extinct at the same time as a bunch of weird marine mammals or if it was killed off by a supernova known to have occurred 2.6 Ma. An earlier study pooled fossil occurrences from around the globe and statistically reconstructed a mean extinction date of 2.5 Ma, with significant error (~3.6 Ma to 100ky in the future being the max and min extinction dates). We found that in the California record, reliable occurrences are only found in early Pliocene rocks. All examples of late Pliocene or Pleistocene teeth were either poorly dated, reworked from Miocene rocks, had poor provenance, or are completely missing (and never photographed) and therefore the identification cannot be confirmed. We thus predicted a 3.6 Ma extinction date. To test this, we re-analyzed the dataset published in 2014 but chucked a bunch of bad data and exhaustively re-researched the stratigraphy of each locality and corrected about 3/4 of the dates in the remaining dataset, and added our new California records. When we analyzed this corrected dataset, our margin of error (the time between the max and min extinction dates) shrank from 3.6 million year long interval to 900,000 years; *probably* extinct by 3.6 Ma (mean extinction date), definitely by 3.2 Ma (min extinction date), and possibly as early as 4.1 Ma (max extinction date). This extinction therefore precedes the 2.6 Ma supernova, as well as the Plio-Pleistocene marine mammal extinction (which in all likelihood was not a mass extinction or an extinction event, rather just a period of higher extinction/origination rate). About 4 Ma is when fully serrated Carcharodon carcharias teeth show up in the North Atlantic, indicating when the two overlapped, however briefly. We think this biotic event matches best - the mechanics of exactly how this was driven are to be figured out by someone else, but perhaps adult Carcharodon outcompeted juvenile O/C megalodon prior to becoming gigantic. Some analyses of Otodus lineage growth rate is going to be necessary. Here's the open access paper here: https://peerj.com/articles/6088/ Here's a blog writeup I did for PeerJ here: https://peerj.com/blog/post/115284881293/early-pliocene-extinction-of-the-mega-toothed-shark-otodus-megalodon-boessenecker/ Excellent summary in Nat Geo: https://www.nationalgeographic.com/science/2019/02/megalodon-extinct-great-white-shark/ CNN: https://www.cnn.com/2019/02/14/us/megalodon-extinct-earlier-scli-intl/index.html Fox News: https://www.foxnews.com/science/megalodon-shocker-huge-killer-shark-may-have-been-wiped-out-by-great-whites Forbes: https://www.forbes.com/sites/melissacristinamarquez/2019/02/14/great-white-sharks-may-be-the-reason-why-giant-megalodon-shark-is-extinct/#6a06986a6486 Daily Mail: https://www.dailymail.co.uk/sciencetech/article-6700495/Giant-50-foot-long-predatory-shark-went-extinct-one-million-years-earlier-previously-thought.html
  10. After a month of needle work, finally finished. This cluster is 65x30cm and I love it, lots of work but I just enjoyed it so much that I am sad it is finished Nothing to work on now This was my first work on a fossil and even though quite scary, very rewarding. I am definitely not stopping here. Besides 29pc of shark vertebrae I managed to expose many other fish vertebrae and bone fragments but the highlit must be an Enchodus tooth. Thank you all for your advise and helpful info on this project.
  11. Our own Robert Boessenecker authored a recently released paper that suggests that Megalodon died out due to competition from the smaller Great White Shark. “The Early Pliocene extinction of the mega-toothed shark Otodus megalodon: a view from the eastern North Pacific” by Robert Boessenecker et al. from PeerJ https://www-m.cnn.com/2019/02/14/us/megalodon-extinct-earlier-scli-intl/index.html?r=https%3A%2F%2Fwww.cnn.com%2F Full text article here: https://peerj.com/articles/6088/
  12. Final clean up

    I decided to expose some of the bone fragments on my otodus vertebrae cluster and now I will like to finish it. Is there any way I can clean the exposed bones? Some solution? I have been working with a needle mostly but can't clean the bones this way without damaging them. I will like to make them pop out after I preserve the whole thing. Any ideas?
  13. Shark tooth ?

    Hi friends, I have four of these shark teeth and I will like to know how the tooth gets to this state. Is it hollowed by somebody or is it found like this? How does this happen that you get only the outer shell of the tooth? Maybe this is common but I have never seen one before today.
  14. Otodus vertebrae

    This week I willl be collecting these Otodus Obliquus vertebrae cluster. It's from Morocco and the size is about 65x30cm, there is 24 vertebrae and the biggest one is around 7cm diameter. There is still lots of matrix on the vertebrae so I was planning to finish cleaning it all. I will like your opinion on this. Should I do it, how difficult is it going to be? I like it the way it is already but I am sure it can be finished better. Is it worth trying?
  15. I’m wondering what the age of the Otodus teeth are in Morocco. Does anybody have any papers on the teeth there? Also, does anybody know how many genera there are there? Thanks
  16. Thinking about selecting a light sand color for the background to make these teeth pop. Here’s an evolutionary display of the Megalodon. Left-to-right: O. obliques, O. auriculatus, O. angustiden, O. chubutensis, O. megalodon. Notice the abscence of cusps from the Meg. The two right most teeth are from Calvert Cliffs, the two in the middle from South Carolina, and the far left from Morocco. FYI @Kurt Komoda @FossilSloth @caldigger @SailingAlongToo @Malcolmt
  17. Very Large Otodus obliquus?

    I would have called this Otodus obliquus, but this morning I was reading, and got confused, about these teeth from Morocco. Now Im not sure what this is called. Even with the tip missing, this tooth measures just over 3.5 inches. RB
  18. Carcharocles megalodon (Joe Cōcke collection)

    From the album Elasmobranchs

    I do not own this rare tooth. It is from the collection of paleontologist Joe Cōcke, which he found locally and gladly allowed me to photograph.
  19. Symphyseal Otodus?

    Seeing this online, one of the hundreds of patho otoduses that come out of Morocco, but I have a suspicion this is a Symphyseal tooth, note the offset root. They thought he same on the parasymphyseal FB group (strange such a thing exists) But, I am not sure, you guys know? It’s not expensive, and I think symphs are cool.
  20. Otodus? Purse State Park Maryland

    Hello all, Braved what seems to be one of the colder and windier days within the last two weeks but I think I might have found my first Otodus! This is from the Aquia formation of the Potomac River, it's a little worn and not in the best of shape but if it's a first I'll take it: Also found this little guy and was thinking Cretolamna sp. but wanted to be certain as I'm just a novice: Thanks for any and all help! This forum has definitely helped me tons and I've chatted with quite a few members shared some wonderful advice and made it even harder to think about anything else except for hunting! Recently was able to find my first Meg(s) and now hopefully and Otodus! Everything is starting to fall into place and I'm really excited for summer to roll around so I can put my kayak to good use!
  21. These were the pick of the bunch of teeth we found amongst the shingle. The three on the left are the best of what my wife found. “Minilodon” on the right was the sum total of my efforts! Beautiful weather, and lovely beaches. Perfect weekend fossicking.
  22. I was able to head to the Paleocene area of the Potomac for a few of hours today, glad I did. I was heading to work, I was quite shocked to see the water was already extremely low even though low tide was supposed to be 6 hours later, I confirmed the tides when I got to work...a strong west wind had pushed the water out and I was set to have some prime time beach time with extra low tides. By the time I was able to slip out of work, I made it to the river about 2 hours before low tide...the water was already lower than I had ever seen it before; this is when I realized that I had too much of a good thing! I kept zigzagging back and forth between the waterline and the old waterline. I finally gave up the zigzag approach and decided to walk the waterline going and the old waterline coming back. The finds were less than what I was expecting but I'm not complaining either, I wish I cold have spent a few more hours out there. My trip maker was my second ever Paleocarcharodon orientalis, worn and much smaller than my first one, I almost discounted it when I originally spied it because I thought it was a broken tooth. A little voice inside my head told me to check it out and I was pleasantly surprised when I picked it up. Total haul. Paleocarcharodon orientalis and Otodus obliquus Close up of the Paleocarcharodon orientalis
  23. Hello all, I stop collecting shark teeth from the cenozoic. I offer all my shark teeth for trade here. There are 3 different location. -Antwerpen, Schelde. Collected in 1970 (not by me) -Balegem. Collected in 1986 (not by me) -Steendorp. Date not known. There is one Megalodon (Steendorp). It's about 8 cm and has all serrations. There is some damage at one side. Steendorp is a closed location were fossils from the Neogene were found. Next there is about 4,5 pound of Balegem shark and ray teeth. These were collected in 1986. There are a couple of Otodus teeth (at least 3 complete), I heard these are pretty rare, but most are from Striatolamia macrota. The biggest one is over 2 inch. This is also a closed location where fossils from the Lutetian (middle eocene) were found. Many complete teeth altough there are also broken teeth in it. No junk. The last location (Antwerp) includes about 1,1 pound of teeth that were found in the Schelde in 1970. Most teeth are broken but there are some nice small ones in it (Notorynchus, Hastalis...). (No pictures yet). At last I will throw in some teeth from Cadzand/Breskens (The Netherlands). There are waaay to many teeth to take pictures of every single one of them, so I just took some pictures of some. If interested, Pm me and I will send you more pictures. I know the pictures aren't the best, but I don't have a camera and my smartphone don't want to cooperate with me. I'm looking for: -Fish -Anything insect -Anything dinosaur (no chunkosaur) - Fossils from Liaoning or similar locations in China - Trilobites - Permian/ Triassic reptiles (teeth,jaws, bones etc.) - Anything I don't have from the KemKem Beds. -All shark teeth that are at least as old as the Cretaceous. - Fossils from the Eocene of Morocco. - ...
