Labor Day. I went into the South Florida jungle and labored strenuously. Mosquito and Horse Fly bites, hands and arms sliced by Saw Palmetto fronds. I did get some rewards.. One was getting to stand in the water while hunting. Almost all marine fossils On the way to the site, I noted scattered bones from a 3-4 year old cow. There were some Vertebrae with fused epiphysis, but at least 3-4 epiphysis laying on the ground. I decided to take photos that I could use for comparison purposes The lower m3 seems to be approximately 40 mm. Note the stylids. I was curious about the shape of uppers versus lowers. I note that the upper M3 is actually smaller in length than the M1 or M2. Just sharing a day well spent. Muscles really sore, lots of cuts, charleyhorse in left thigh...

I originally thought that 1 might be some piece of turtle, but it looks very strange to me up close. It is divided into many tiny cells unlike any bone I’ve seen before. It also seems to have a generally geometric shape, with the top end pointed outwards and the bottom end having two concave divots (terms “top” and “bottom” refer to the orientation in the numbered picture). Im quite sure 2 is either to a great white or megalodon. Normally I would say great white due to the general lack of a bourlette, but it is so small that I’m uncertain. I do not know if 3 is identifiable, but I was already posting the first two so figured I might as well include it. I have never found a bone with a long indent running along the middle of the outside of the bone. Just thought it was curious.

My son found what I think is an oddly shaped Megalodon tooth (grey tooth) on the beach in South Carolina near Charleston. The tooth seems small, blunt, and rounded. It's very thick, but only about 7cm long. Aside from the big chip at the tip, the enamel on the outer edges is intact but wavy, so the deformation isn't from breakage or wear in the ocean. I included another tooth I found on a beach in NC (Topsail Island) for comparison (I don't know the species of that one either -- maybe another meg?). The back of the enamel on the meg tooth is split and there's a weird, circular nub the top where the enamel ends which looks like a growth. It's definitely part of the tooth and about 2-3mm above the enamel. The split in the enamel on the back is also raised and you can feel a noticeable ridge all the way down the back of the tooth. I provided a close up of it. Can anyone tell me: 1. Is this a meg tooth? 2. What might be wrong with it? Why is it so short and what might that split and nub on the back be? 3. What's the species of the normal-looking black tooth used for comparison? Thanks

If you are planning to go to Summerville, SC for your first time, and have been hoping to find Shark Teeth, please read this. My Advice: · I advise only going if you know someone with known locations, or otherwise plan to hire a company or a guide (I do not have someone to recommend). Finding teeth on your own is quite difficult. My hunt: I got lucky this time on a 3-day trip. After having visited Summerville years before with my son to great success, we went through over 25 spots (August 2023) with only two teeth found. We were discouraged. Luckily, we found one location that netted us the teeth shown as a last-minute discovery at the end of day 2. We returned on day 3 after morning rain. Our goal was to find a Megalodon tooth (even broken) of 3" or more, which we were successful!! If it wasn’t for that one spot, the trip would have been disastrous. Unfortunately, the spot that we found will soon have a structure over it so I cannot say this opportunity exists for the future. What didn’t work on my trip? · My known, secret spots didn’t have shark teeth this time. · I had researched fossil formation areas, inland tides, and elevation maps; yet the locations we visited didn’t have shark teeth. We found the right layers, but not teeth (even with low creek flows). What has changed in Summerville? I believe: · Inability to use tools is impactful (there is a law against it). · I believe the hurricane years ago exposed quite a bit of fossils, but since then the volume of fossils are not being exposed quickly. I should have realized there have been a lack of YouTube postings over the past few years. If you go to the Beach without a guide/company: · Going during the day, even at low tide, has too many tourists looking for fossils. We made this mistake. · Go first thing in the morning for better odds. · Go after a storm. · Find a location away from tourists. We are pleased with the results in the images below. I hope this information is useful. Thank you

This is something I just found out yesterday, but feel is amazing enough to share on the fourm (especially to all those who study Carcharocles (Otodus) megalodon)!!! I was researching shark diversity during the late Eocene when I came across some info on a fossil Shark rostral node specimens from the Zanclean Pilocene sections of the Yorktown Formation dating around 5.3-3.6 Million Years ago in what is now North Carolina. The Specimens USNM 474994, 474995, 474996, 474997, 474998, and 474999 belongs to juvenile sharks (with USNM 474998 belonging to an individual shark of about 1.46 meters (4.8 feet) in length). Originally believed to be rostral nodes of a Lamna sp., they were reanalyzed and discovered by Scientists Dr. Frederik H. Mullen and Dr. John W.M. Jagt to be from Juvenile Otodontidae Sharks. (also, USNM = National Museum of Natural History, Washington D.C., U.S.A.) Mollen, F.H. and Jagt, J.W.M. (2012). The taxonomic value of rostral nodes of extinct sharks, with comments on previous records of the genus Lamna (Lamniformes, Lamnidae) from the Pliocene of Lee Creek Mine, North Carolina (USA). Acta Geologica Polonica, 62(1), 117–127. https://www.researchgate.net/publication/262142193_The_taxonomic_value_of_rostral_nodes_of_extinct_sharks_with_comments_on_previous_records_of_the_genus_Lamna_Lamniformes_Lamnidae_from_the_Pliocene_of_Lee_Creek_Mine_North_Carolina_USA Reconstruction by Tyler Greenfield, 2021 This research also strongly indicates/directly suggests these rostral node specimens might belong to fetal or newborn individuals of Carcharocles (Otodus) megalodon!!! If correct, it would be the one of the most significant finds in terms of non-tooth C. megalodon fossil material since the relatively recent discovery of specimen IRSNB P9893 (also known as IRSNB 3121), a pretty complete C. megalodon fossil vertebrae column from a Miocene Formation in what is now Belgium!!!

Since moving to Gainesville I've had the opportunity to work more closely with the Florida Museum of Natural History (FLMNH). In addition to volunteer digging at the Montbrook site I also get to work on prepping fossils in the prep lab on campus. This brings me into contact with the major players at the museum which is a great fringe benefit to be able to have access to chat with those with lots of paleontological experience. Bruce MacFadden is on the second year of a program to develop an interesting course plan for STEM teachers around Florida. It's an interesting program combining science, paleontology (kids love fossils) and AI which is really trending these days (I promise this text was not written by ChatGPT). As part of this program the teachers will train an online AI program to recognize megalodon teeth from photos. After training one of the things they will do with the class is to see how the AI will do at recognizing partial megalodon teeth (AKA fraglodons). Since each teacher is given a number of fraglodons to use while teaching this program to their students we have a need for less than perfect megs. The teachers get to keep the fraglodons as they will (hopefully) continue to teach the program year after year. I've been able to contact some fossil hunters I know who would likely have a cache of broken megs looking for a good use. Those donations were helpful for the first cohort of teachers but the second cohort (new STEM teachers) are getting ready to work this program into this year's class and we are in need of new fraglodons for them to use. Bruce brought in some of the fraglodons they used while teaching the program this year so I could take a photo showing the variation in completeness. Note that these are all Florida fraglodons so they are all the usual grayish-black in coloration. Bruce mentioned that color is not a factor and broken megs of any color would be very welcome (even little corners of a root with just a bit of serrated enamel showing). He said that they could really use around 100 fraglodons so I'm putting this out to the forum to see if any of you have some of these less than perfect teeth sitting around in your collection looking for a higher purpose. If you think you have some fraglodons that would help this year's STEM teachers get kids interested in AI and fossils, please contact me via PM. Thanks in advance for all who have something they'd like to contribute. Cheers. -Ken

So last weekend picked this up from another collecto. About 51 pieces of partial Megalodon teeth from Antwerp & Borseek, Belgium. These are quite more rare than you see in the USA or Indonesia for example. Biggest one measures around 5 inch.

Advice needed on Meg tooth
RhinoWater posted a topic in Is It Real? How to Recognize Fossil Fabrications
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.

Scientists find new clue in what led to megalodon’s demise
Denis Arcand posted a topic in Fossil News
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-

Indonesian Megalodon Teeth - Real or Fake?
ferrof88 posted a topic in Is It Real? How to Recognize Fossil Fabrications
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!

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

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]

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

I've read, that one of the Megalodon nurseries; was likely in Panama. I've also read, that Megalodon likely used the easy access between the Atlantic and Pacific; in ancient Panama. I have not seen Megalodon specimens, from Panama. There are teeth from many different locations, available for sale. Where are the teeth from Panama?

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...

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....

Was the Yorktown Formation Otodus Megalodon's last stronghold?
Joseph Fossil posted a topic in General Fossil Discussion
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?
