  1. Hey everyone! i was wondering If I could get your opinion on two things with this tooth. 1)does this look like It was found in a BV, golden beach, Etc. location? 2)I had someone suggest that this may be a transitional GW, due to the fact that the serrations are uneven, and get larger, and smaller depending on where you look, even though the serrations don’t seem damaged.
  2. Slow day on the beach, not finding much of anything, when right before I turn around to head back I see a perfect 4” Meg sitting in ankle deep water! Total trip maker!
  3. My Best Megalodon Tooth Yet!

    Hi everyone! This is my first post here on the forum in what feels like forever. I'd like to be active here again, and thought there was no better way to kick it off than showcasing my meg tooth! Some of you may have already seen the tooth on my Instagram, Facebook, or YouTube, but I wanted to make a post on here as well. I found the tooth last week along Calvert Cliffs. It's approximately 4.1" slant height and in near perfect condition. It even has that iconic Calvert Blue color on the crown that I love so much! I've been dreaming about finding a tooth like this ever since I started collecting a few years ago, and my dream has finally come true! Check out the pictures below and the YouTube video if you'd like to see how I found it. Hopefully the first of many great finds this year!
  4. Hello all. I was wondering if anyone on here is from (or very familiar with) coastal plain South Carolina. I am not fishing for spots at all, in fact I have a vacation rental on a nice piece of land west of Summerville that I picked and paid for in hopes that we would have fossiling accessible from our home base. We have river access and the land is ripe with creeks. I would like to network with someone knowledgeable about the area to find out if where we are staying might be fossiliferous. This is mostly my teenage son's hobby, but we will definitely hunt as a family. We did hunt creeks in Florida a couple years ago and had a great time so we are at least somewhat familiar with the methods. What it comes down to is I don't want to schedule an excursion and pay a guide in South Carolina if an expert can tell us that we probably can find fossils right under our nose where we are staying.
  5. This tooth has popped up on my radar. It is an interesting looking tooth, especially for coming out of Georgia. Anyone seen similar teeth from that area??
  6. Scientists expected meg teeth to be adapted to large lateral forces but found that when size was removed as a factor, other Megatooth sharks had better tooth shapes for handling the stresses. Done with finite element analysis. https://phys.org/news/2021-01-reveals-teeth-functioned-evolved-giant.html

Ontogenetic growth pattern of the extinct megatooth shark Otodus megalodon—implications for its reproductive biology, development, and life expectancy. Historical Biology. Abstract: The extinct megatooth shark, Otodus megalodon (Lamniformes: Otodontidae), is known primarily from its gigantic teeth in the late Neogene marine fossil record. It is known to reach at least 14.1‒15.3 m in length, but its reproductive biology and ontogenetic growth pattern have remained largely in the realm of speculation. Here, we examined incremental growth bands in fossil vertebrae of a 9.2-m-long individual O. megalodon, revealing that the shark was born large, 2 m in length, and died at age 46. This large size at birth is characteristic of lamniform sharks and is indicative of live-bearing reproduction along with embryos’ intrauterine cannibalism behaviour in the form of oophagy. The trajectory of the generated growth curve beyond the age of death and the maximum length (about 15 m) calibrated from the largest known teeth of O. megalodon suggest that the species had a lifespan of at least 88–100 years with an average growth rate of about 16 cm/yr at least for the first 46 years. As one of the largest carnivores that ever existed on Earth, deciphering such growth parameters of O. megalodon is critical to understand the role large carnivores play in the context of the evolution of marine ecosystems.
  8. Got these this week. Still have a few more Megs on the way in but these arrived today. first is a red tooth from N.C. It's a bit over 3 inches. Not perfect but it has a great color. A little damage on the serrations and the tip is also gone but the enamel is gorgeous. I believe these come from the miocene era ? Next one is a 3 15/16 green tooth from Indonesia. I believe it is miocene era tooth. It's got some cool coloration. No tip but that's ok, that's what made it affordable. 3rd on the list is my Jumbo tooth. Also a NC tooth but this one from off the coast in deep water. It's not as good of condition but at 6.15 inches long and 5.10 inches at the widest point I am not complaining. It has some cool colors to it and is just a massive tooth. I have a pic of it with a tooth from Bill Eberlein that measured 6.06 inches from Florida. It is a tad shorter and narrower, but thicker and in slightly better condition. Weight is similar, but I would give the NC the advantage there just from holding them. Last tooth is a new one from Bill that isn't up to the typical standards I buy from him at this size, but that color outstanding to me and really unique. Bill said it was 4.98 inches, though my calipers make it hard to make the call between that and full 5 inches, but I will defer to Bill on this. Its a nice tooth even with the root damage and the chips in the blade. That blue color really pops out at you in person. Then we have a couple of Ammonites from the Duck Creek formation. The big one is 15.1 inches in diameter and has some fabulous details to it. The smaller owe isn't as nice but I'm not complaining as my 8 year old daughter loves it. Gonna try to get up to the Waurika sight when traveling through there and see what there is to see.

  11. More megs incoming

    Well after I tracked down and got my long pursued T Rex tooth in 2019(it's posted here somewhere) I took a bit of a break from fossils till recently. I have several new nice Megs coming my way from a variety of locals. Also have a huge ammonite I need to pickup. Will post them when I get them but this one is here already so I will share it. It isn't a perfect tooth but I think it looks astounding. I wasn't certain it was legit...thought a repair was possible, so I offered a low price on it and shockingly the seller accepted. Well lack light inspection, comparing it to my other teeth, and going over it witha pick and a comb and she appears to be legit. Seller said Phillipines though I guess it could be Cuban. Not truly concerned on origin I just love the look of the enamel on this tooth. Has the point and serrations as well. Really pleased with this one.
  12. Indonesian Shark Tooth

    Hi everyone, I have here a 1" tooth identified as a Megalodon from West Java, Indonesia, allegedly a new creek locality. I know that smaller Megs may not necessarily have bourlettes, but there do not appear to be serrations. This could probably be explained by river wear. In any case, might this be a Meg, or could it be something else? Best, Bellamy
  13. Greetings all. I hope you're ready to give 2020 a good boot in the butt to bring in 2021. I know my foot is locked and loaded. A while back I purchased this shark tooth fossil from an online auction. It was listed as a "great white". Despite the description being wrong, the price was right. I believe that Angustidens are tricky to tell apart from Auriculatus teeth. Since, and if, this is the case, would the color of a tooth, the root in particular, be enough to establish a tooth that is likely from the Suwanee River environs? From a quick web search it seems that teeth that look like this one does tend to be from the Suwanee River and are labeled Auriculatus rather than Angustidens. So maybe the quick question is, which type of shark tooth is most likely to come from the Suwanee? The seller didn't provide any location to go with the description. It just seems that the muddy brown color of the root seems to often come from the Suwanee River. Any input is greatly appreciated. Have a safe and healthy New Year, all !
  14. Restoring teeth

    Hey! does anyone have any advice for a beginner on how to get decent serrations while restoring megs?
  15. Hey all - I had a great week of shark tooth hunting in Charleston, SC and wanted to share my top favorites from each day Tuesday - Friday. Got to appreciate when it goes right!!
  16. Shark tooth from childhood

    Hi! was wondering if someone could take a look at this tooth a friend sent me. She said she got it as a kid about 20 years ago from a science/geology store in our local mall. She would like to know if it is real, and if so what kid of tooth is it. Thanks for your help! You guys are the best
  17. I Found This in an Antique Store

    I found this tooth in a box at an antique store in TN. It had a tag on it that said arrowhead. What species is it? It measured 2-1/4"
  18. Hi guys I have 2 shark teeth, a megalodon from South Carolina and a chubutensis from Peru, both teeth are authentic but have different characteristics for example the enamel between the crown and serrations on the megalodon is really standout and flickers in the light, how ever the chubutensis is barely noticeable and bland, also the root on the megalodon is almost rough feeling as the chubutensis is really smooth, is this to do with how they have fossilised different around the world, I’m keen to hear what u have to say see photos below ! Thanks in advance
  19. Up for trade is this beautiful 4.7” Megalodon tooth from Indonesia. It has repairs to cracks along the middle of the blade but no restoration as far as I can tell. There is a very tiny patch of fill on the back side smaller than a dime. I am open to all trade offers. This tooth has some of the best colors you’ll see on a tooth and has razor serrations and tip. It even has some sea shells imbedded in the root
  20. I started collecting megalodon teeth about a year ago and this was my first tooth. Now that I have a few others, I’ve noticed possible discrepancies with the tooth. My other teeth have a grainy, gritty textured root but this one has a smooth textured root with a shiny appearance. The root of this tooth is also very smooth/slippery to the touch, whereas with my other teeth, the root is fairly rough to the touch. Also, where the enamel meets the bourlette, that is also quite smooth but on my other teeth, it is fairly sharp and jagged in comparison. Any advice is appreciated as I’m still fairly new to collecting. Thanks in advance!

  22. I have seen several names for megalodon all with a different genus, which is correct? Edit: Another question, is cretalamna appendiculata the ancestor of otodus obliquis? Is there anything in between those if they are related? Do we know megalodon ancestry past C. appendiculata if it is directly related to O. Obliquis?
  23. Shark Tooth ID - Florida (Part 2)

    Please help me ID these shark teeth that were found on the west coast of Florida (near Venice) over the past weekend. My belief is that the top row could be Great White and/or Megalodon (very nice serration on the largest/first one), the second row is either Bull or Dusky, and the third row is Hemipristis (Snaggletooth). As for the fourth row... the jury is still out. I am most intrigued by the third/tiny one (from left to right). It looks different from anything else I have ever found. Very compact, lots of detail, and oddly shaped. Any ideas???
  24. I am a fairly new collector of fossils (when it comes to purchasing them that is) and was looking for some advice on whether or not this small megalodon tooth I recently purchased that comes from the Hawthorne Formation in Georgia is the real deal. Any help would be greatly appreciated. Cheers!
