  1. Hi guys could you help me authenticate this megalodon tooth fossil please I bought it from a store that sells lots of crystals,meteorites etc. called [seller name redacted as per forum rules] in Sydney. The colour of the tooth is quite a blackish red colour and it was said to be found in Morroco is this normal ? IMG_0946.mov
  2. Is this tooth real with no restorations and is it a good piece to collect ?
  3. I have another Megalodon tooth here can you guys help me authenticate it. It is said to be from South Carolina and it’s a partial tooth IMG_4171.mov
  4. Hello everyone, I'm a new fossil collector and have been wanting to purchase a megalodon tooth for a while. I have come across this tooth that's fairly priced and am wondering if it's too good to be true. The seller is unable to confirm the place of origin. Any advice or help is kindly appreciated. Also, how would one identify if a Meg tooth is real or a fake/replica? Thank you and appreciate any help given.
  5. Megalodon, once feared as a cold-blooded killer, was actually partially warm-blooded, with a body temperature 7 degrees Celsius higher than the surrounding seawater. This trait likely contributed to its massive size and prowess as a predator. However, the need to maintain a high metabolism might have made it vulnerable to extinction when the Earth cooled. Understanding ancient sharks like megalodon can provide insights into the challenges faced by modern apex predators, such as the great white shark, due to climate change. https://www.sciencealert.com/we-finally-have-a-new-clue-about-what-wiped-out-the-megalodon https://www.pnas.org/doi/full/10.1073/pnas.2218153120
  6. Hi there! I have a chance to purchase Indonesian Megalodon teeth wholesale, but I want to make sure they are real first. Of course the seller says they are. The teeth are 10-13cm and seem to be in excellent condition, which is what draws my skepticism. Pictures are attached. Any info/informed opinions are greatly appreciated. Let me know if you need any other info. Thank you!
  7. A whirlwind week... I was visiting my daughter for father's day weekend. On Thursday, the Museum of Natural History, Lincoln Memorial, the Vietnam black wall. Lots of excitement and I was truly wasted by the time we got back to Union Station. There is so much to see... hours does not make a dent.... Everyone would take different photos... I took these in the initial Galleries... Lamarck's Carinaria... New fauna... This is a model, many exhibits are the real thing.... Looking to the ceilings...A Right Whale and a Basilosaurus Lots of Crinoids.... I had thought that @minnbuckeye had captured a few of these, but maybe not.... On _ward and up ward , more galleries to visit Although really small in size, I was impressed by an impression on the rock.. This Smilodon fatalis also got my attention, How about the "sheath" over each claw.... Does any TFF member have one of those ? Between Galleries, you see some transitional modern items.. There are complete floors dedicated to modern mammals... Never got there... but what do we have here? And once again, on to other floors , other galleries.... x A Stingray from Lebanon, capturing an image from the Cretaceous. A Flightless Bird.. I guess related to Titanis walleri, another revelation for me Marine Mammal Definitely large tusks and then Unitatherium.... look at those sabers.... Fantastic time.. learned lots of new things just walking around, taking photos.. If you love fossils, definitely a bucket list item.. I figure I saw about 4% of the exhibits available... and in the last transition space.....60 foot model I'll share one other experience.. I visited the Baltimore Aquarium and stopped by Faidley's seafood market and purchased Chesapeake Bay Oysters for $2 each.. I love seafood, and my daughter , Crystal, has excellent culinary skills... Mackerel, Cod, Salmon, Shrimp, Crawfish, Abalone, but the absolute best were the Oysters Rockerfeller... Raw, Drago, Rockereller Bon appetit....Crystal saved the shells of both oyster and abalone
  8. Hi all I've had this tooth for a couple of years now, I think it was purchased off a website [price removed as per forum rules]. I've passed it off as real but I'm not sure if it actually is because of its cheap price. Are there any signs this is a fake? Pen shown for size

    My Collection So Far

    Hey everyone, I'm very new to fossil hunting and collecting, but the collection is growing, and I'm really wanting to get out hunting a lot more. Iv'e looked around North wales and mostly found carboniferous fossils such as coral and also had a few trips to the east coast of England (mainly Whitby and Norfolk) but haven't had a lot of luck there yet except parts of ammonite and the odd belemnite. So anyway, my collection so far. My main interest in ice age animals, especially European and British. But also a keen interest in prehistoric marine life. Fossils so far: Steppe Bison (Bison Priscus) cranium Irish Elk (megalocerous giganteous) cranium Partial Irish Elk (megalocerous giganteous) Left Antler partial Juvenile cave bear (Ursus spelaeus) Jaw Partial Cave lion (Panthera Spelaea) Jaw Partial Woolly Mammoth (Mammuthus primigenius) Right side of Jaw with M2 Molar (and M3 Molar Erupting) Woolly Mammoth (Mammuthus primigenius) Hair sample Woolly Mammoth (Mammuthus primigenius) Fecal sample Woolly Rhino (Coelodonta antiquitatis) hair sample Fossiled Whale Rib bone that has been eaten by a Megalodon (Otodus Megalodon) Megalodon (Otodus Megalodon) Coprolite British Clactonian/Acheulean Bitface Flint Handaxe Lots of smaller pieces of ammonite, Belemnite, carboniferous corals and shells. But lets start off with my most recent purchase. Very happy with it! [removed seller name, as per forum rules] A Half Lower Jaw with M2 and M3 Molars of a Woolly Mammoth. Latin Name: Mammuthus primigenius Site: North Sea, ‘Doggerland’ area Age: Approximately 40.000 years old [removed seller verbiage as per forum rules]
  10. Today, I went to the Peace River with frequent hunting partner Steve and , as a treat, my son Jack. My son is at Florida's Atlantic coast for another 4 days and we scheduled today to meet at the Peace River. This is only the 7th time we have hunted together and usually we find interesting and impressive fossils. Beyond the numerous small shark teeth that are available in many sections of the Peace River, the 3 of us found few other species. All of us found a couple of small megs in the 36 to 40 mm range. That was pleasant.. Here was my set of interesting finds. Megs, Dugong, Stingray, Seashells, Dolphin bulla. This was just icing on the cake...My birthday is Tomorrow. Got to celebrate with my son in the sunshine hunting fossils. How sweet it is...
  11. At first I was skeptical of this one, but it looks credible. I smell a Franklin Mint necklace becoming available soon. Or a lot of meg jewelry that didn't move well to date, selling soon. Cheers. Megalodon Necklace
  12. Is there a tutorial or a video showing how to repair Megalodon tooth enamel? Is anyone aware of a repair service?
  13. Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!
  14. Went out yesterday for an unusual weekend trip.. I had a week long trip to Northeast Florida, and thus missed some of this precious hunting time, before the summer storms arrive and fill the river to its banks. Since my hunting partner had missed hunting for the week, he wanted to go out yesterday and tomorrow. Just being accommodating plus I love being in the river. Here are my finds for the day, sorting out the vast majority of small shark teeth. I showed the Mastodon and small Meg in an earlier post, so here I plan to focus on the rest... I was picking up a lot of broken teeth and bone and decided to keep more than I usually do. SO if I saw enamel , I kept it . The with the bone I found a piece of fossilized wood Lower left, and I thought about its texture compared to bone (ribs). Then I started keeping any fossil with "strange" texture.... A close up of the wood... Why is this wood instead of bone, I asked myself... and started picking out random bones for comparison purposes. Another interesting find...was some mud_rock with a little silicified layer attached...It was not until I was taking photos that I noted the blue druzy orbs... nice surprise Here is one I almost tossed.... just too small and fragmented. I do not know enough about fish jaws because they are very hard to find... but I did find one that I had identified. They looked to be very similar.. I had found a tooth for the 2021 Jaw, Then we identified the 2021 jaw as Alligator gar, and compared to this jaw from Nate, SO I am wondering if this new find is also Alligator gar.. A bit small... Note the enamel on the left side of the photo... There are lots of other broken fossils in the group shot that triggered my curiosity and demonstrates the diversity of fossils in the Peace River... Let me know if you would like to discuss / comment on any....
  15. Hello everybody So this is a question not directly regarding fossils, but I feel this is nevertheless the right place. Is there any information on how big the teeth of modern great white sharks can get? For Megalodon there is a great amount of information regarding the size of the teeth. But for modern great whites I only find information about the size of the whole shark. I would like to make a small display with my 5.64 inch Meg tooth and a modern great white. I was able to get a 2.4 in modern white shark tooth. But I dont know if this is big or average. Thanks for your help
  16. I've recently read a 2020 scientific paper describing pretty accurately the multiple nurseries that Carcharocles (Otodus) megalodon had established to raise young between the Miocene-Pliocene 23-3.6 Million Years ago (not just a single nursery in what is now Panama as previously thought). Herraiz, J. L., Ribé, J., Botella, H., Martínez-Pérez, C., & Ferrón, H. G. (2020). Use of nursery areas by the extinct megatooth shark Otodus megalodon (Chondrichthyes: Lamniformes). Biology Letters, 16(11), 20200746. https://doi.org/10.1098/rsbl.2020.0746 https://royalsocietypublishing.org/doi/10.1098/rsbl.2020.0746 What I also found interesting about this paper was that the geologic latest nursery area the researchers identified is what is now the Yorktown Formation, North Carolina. Images Credit: https://royalsocietypublishing.org/doi/10.1098/rsbl.2020.0746 C. megalodon went extinct in the Mediterranean as a result of the Messinian Salinity crisis 5.59 Million Years ago. The emergence of Orcas (Orcinus) and the Great White Shark (Carcharodon carcharias), a decrease in diatom diversity during the middle miocene-pliocene, and the miocene formation of the Isthmus of Panama which changed ocean current patterns also helped caused a decline in C. megalodon's population by the Pliocene. But this 2020 paper has got me thinking about where did C. megalodon as a species make its last stand? Was the Yorktown Formation in North Carolina C. megalodon's last stronghold?
  17. I recently added a few new big teeth to my collection which prompted me to take some pics of the largest teeth I have from 3 species - Carcharodon hastalis, Carcharodon carcharias and Otodus megalodon. One of the recent acquisitions is the 2.7" C. hastalis. It's not in great condition but it's not every day you come across a specimen this size so I had to buy it! While the 2.7" C. hastalis and 2.6" C. carcharodon teeth are approaching maximum size for each species.... the O. megalodon teeth make them look small. A little perspective on just how large that shark got!
  18. I just bought this megalodon tooth online, and I was wondering if someone could help me out and see if it’s real. My main concern are these notches/dents on the sides of the tooth (close to the root). It kind of makes it seem like it’s been molded. I’m not sure if this is natural or not.

    Going to Wonderland

    I know that I went hunting yesterday. My neck and back muscles are screaming at me. We go to places we have visited before... In this case, some sort of coral reef or shell bed that was laid down , most likely in the Pliocene. Steve, who worked in the Phosphate mines said that there were 3 layers of shell beds in Bone Valley mines where he worked. Land mammal remains between the shell layers. In some locations, the Peace River has brought those layers close to the surface. I call this location wonderland. When ever I go there ... I wonder.. I wonder what layer I am finding.. Pliocene ? Miocene, whatever the 1st layer is... I wonder what process created what I see.... I went back in TFF to find that I have not revisited this location in more than 2 years. Back to the yesterday, A Barnacle.... This is solid rock... or blended silica with sand , mud , shell ..I wonder if the Barnacle "shell" filled with sand or mud and the silica transformed the whole thing to rock, sand mud , everything.. and I always wonder about the process details... Shells..... ..I wonder if we can identify the shells because that might tells us if there were Pliocene or Miocene.... I wonder about the process details... This is not hard fossilized rock like the barnacle... This is like mud rock,, that would break or crumble pretty easily So the shells existed on the bottom of the ocean, the ocean receded, Peace River brings in fresh water, somehow it is making mud-rock (which is common in many forms)... the shell sticks to the mud rock, then the silicification comes along changing the shells ,not the mud-rock., and the whole thing gets worn down until I pick it up.... Shell # 1 2nd Shell ..The rock weighs 40-50 pounds... a heavy item on the trip back in my kayak..Is this whole bivalve there ? Was this one transformed to Silica.... I wonder ... I also find botryoidal chalcedony, some bigger... some smaller. I think this formed in a "cave" in a echinoid sand dollar... Finally for those who appreciate more traditional Florida fossils, I found some of these also. Really like this tooth, it exihibits serrations with feeding damage and those CUSPS !!!... I wonder if if cusps on Megs is only true of Pliocene Megs. I am sad to say that it looks like the chipped the root on recovery. I guess what it comes down to is I am a wondering kind of guy....Enjoy
  20. The Chondricthyans (including the sharks and rays) have been around and keeping the ocean's ecosystems healthy for about 420 Million Years. Today, in celebration of this, I've decided to do a little fun post and list the eight times in Earth's history truly massive chondricthyans have emerged. Hope you all enjoy!!! The First is the Devonian, where there is at least one confirmed fossil (CMNH 5238) of a large currently unnamed Ctenacanthiform shark that reached lengths of 4.2-5 meters (13-16 feet) in length. https://www.mdpi.com/1424-2818/15/3/318 The Second is the Mississippian stage of the Carboniferous (358.9-323.2 Million Years ago), a golden age for chondricthyans. The Early Carboniferous saw the emergence of Giant Ctenacanthiform sharks like Saivodus striatus, which grew up to 10-11 meters (32-36 feet) in length. https://www.uky.edu/KGS/fossils/fossil-of-the-month_2022-07_Saivodus.php https://www.uky.edu/KGS/fossils/fossil-of-the-month_2022-07_how-big.php https://www.nps.gov/articles/000/fossils-of-the-2023-national-fossil-day-artwork.htm The Third is the Pennsylvanian stage of the Carboniferous (323.2-298.9 Million Years ago). Like the Mississippian, the Pennsylvanian was also a golden stage for Chondricthyans where large Ctenacanthiforms continued to thrive and large Eugeneodontida edestoids like Edestus (which could grow up to 6.7 meters (22 feet) in length) emerged. Large Ctenacanthiforms from this time include the unnamed Graham Formation Gilkmanius sp., which grew up to 7 meters (22 feet) in length. https://bioone.org/journals/journal-of-vertebrate-paleontology/volume-37/issue-3/02724634.2017.1325369/A-Pennsylvanian-Supershark-from-Texas/10.1080/02724634.2017.1325369.short The Fourth is the Permian (298-252 Million years ago). There were some large sharks, like the Ctenacanthiform Kaibabvenator (which grew up to 4.8-5.48 meters (16-18 feet) in length). But Eugeneodontida by this point contained the largest Chondricthyans alive at this time including Helicoprion (which grew up to 7.6 meters (25 feet) in length) and Parahelicoprion (which could grow up to 12 meters (36 feet) in length). https://www.academia.edu/29941296/Chondrichthyan_and_actinopterygian_remains_from_theLower_Permian_Copacabana_Formation_of_Bolivia https://doi.org/10.1002%2Far.24046 The Fifth is the Early Cretaceous (145-100 Million Years ago). Though the time's aquatic ecosystems was dominated by large marine reptiles, large sharks managed to emerge and fill ecological niches from time to time. This includes the Early Cretaceous Shark Leptostyrax, which grew up to 6.3 meters (20 feet) in length. https://www.researchgate.net/publication/277782424_A_Gigantic_Shark_from_the_Lower_Cretaceous_Duck_Creek_Formation_of_Texas The Sixth is the Late Cretaceous (100-66 Million years ago). Aquatic ecosystems still were dominated by marine reptiles, but large sharks were indeed present. This includes Cretodus crassidens (which grew up to 9-11 meters (29-36 meters) in length) and Ptychodus (which grew up to 10 meters (32 feet) in length). https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0231544 https://www.cambridge.org/core/journals/journal-of-paleontology/article/morphology-and-paleobiology-of-the-late-cretaceous-largesized-shark-cretodus-crassidens-dixon-1850-neoselachii-lamniformes/A670012A44DDC68FC098BB8C73368408 The seventh is the Miocene-Early Pilocene (23-3.6 Million Years ago). This period saw the rise and reign of some of the largest sharks known currently in the fossil record, including Carcharocles (Otodus) megalodon (which grew up to 17 meters (55 feet) in length). https://www.uv.es/everlab/PUBLICACIONES/2017/2017 Martinez-Perez et al HB miocene sharks.pdf https://www.science.org/doi/10.1126/sciadv.abl6529 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9385135/ The eighth is the Early Pliocene-Late Pleistocene (3.6-0.012 Million Years ago). This period saw the last remnants of the large 20 foot + in size carnivorous sharks from the Miocene-Pilocene mega shark era not including the non-Great White shark (Carcharodon carcharias) and not including the large plankton eating sharks make their final stand. These include Hemipristis serra (which grew up to 6 meters (20 feet) in length) and Parotodus benedeni (which grew up to 7.6 meters (24 feet) in length). https://www.app.pan.pl/archive/published/app63/app004542018.pdf https://www.researchgate.net/publication/364591134_A_previously_overlooked_highly_diverse_early_Pleistocene_elasmobranch_assemblage_from_southern_Taiwan https://www.cambridge.org/core/journals/paleobiology/article/chondrichthyan-fossil-record-of-the-florida-platform-eocenepleistocene/2835CCEC27DC8EE0B24A5B62B1416618 I hope this is helpful?

    Help to Identify Big Shark Tooth

    Hi everyone! In an online auction I found this shark tooth. It is indicated as "Otodus megalodon tooth", found in West Java, Indonesia. Unfortunately there are no further details on the provenance. The shape looks very different than typical Megalodon teeth, but I admit I'm not an expert. Could it be another species of Otodus genus?

    What kinda teeth are these?

    Hi, I went to the fleamarket and bought these. One is some kind of shark tooth, the other a crocodile tooth from the miocene I believe. What do you think?
  23. Shellseeker

    Some finds

    Out with friends, going to a Miocene site that always is challenging for me to go and return. It is a Miocene site because the large majority of fauna found live during that era. It did not disappoint. I started in the 1st sieve with a Meg, somewhat distressed and puncture marks from a bite during a feeding frenzy... Note the 3 bite marks on the lower edge. This is my 4th such Meg There were many finds but one certainly rarer in the Peace River than Megs is a lower Mako in good shape, with a lighting strike on the labial side.. This is my 3rd of this size in 15 years. So, what about the request for Identifications. Here is one... This Dolphin Tooth has not been identified for Florida.... and certainly not for species.. Last time I found it , we discussed Harry's GREAT picture that is the best identification out there for teeth that look like this....If someone has a good research paper on Kentriodontidae teeth that matches these two teeth I have found, please point me to it... Here is my previous version: Here was a thread that asked for an ID on a similar tooth from Maryland, but the ID was "Dolphin" tooth... So finally, something to ID.. To show how my luck was holding, I went over to a pile of discard rocks from a previous hunter of this site . Unbelievably this was sitting on top... I have never seen one like this... Th first photo seems 3/4 Stingray denticle and 1/4 trilobite. I have plenty of these that are flat on the bottom, and found 2 or 3 today. But this is unusual for me in Florida. Is this shape common in Maryland or North Carolina ? It almost looks like a druzy or silification in the center of this last photo.. Thanks for looking.
  24. Dear all, I have recently encountered a very good deal on the tooth attached below. However, the deal is too good so I wonder, is it a fake or is there a chance for it to be real. Deal is around (price removed) for a 10.5 cm tooth Thank you for your help Best
  25. Hi everyone! I've been reading a bit about Megalodon's ancestors and trying to update my knowledge and I'm coming across some conflicting information. It seems everywhere I look has a different age range and there seems to be a debate between the genus. Some use Carcharocles and some use Otodus. I've been using Carcharocles for the lineage, is that officially out of date? Also what are the age ranges of the ancestors Auriculatus, Angustidens, and Chubutensis? I can't find any consistent numbers and some places seem to suggest they coexisted (Auriculatus with Angustidens for a short time then later Angustidens with Chubutensis etc.) is that true? Any insight is appreciated as always!
