    My shark teeth collection

    Here is my shark teeth collection. photo 1 Species: Carcharocles megalodon Age: 2,6-15 million years (Miocene-Pliocene) Size: 9,5 centimeters Localisation: Georgia River (Georgia) Formation: Hawthorn photo 2 Species : Isurus hastalis Age: 9 million years (Miocene) Size: 4,8 centimeters Localisation: Copiapo, Chile Formation: Bahia Inglesa photo 3 Species: Squalicorax pristodontus Age: 70 million years (Upper Cretaceous) Size: 2,9 centimeters Localisation: Morocco Formation: Kem Kem B
  4. Hello everyone!)) Need help of paleontologists and paleoichthyologists with identification of eocene shark teeth from Russia. I'm not professional, just a fan and rooky, so I choose possible species options for every tooth, according to books and scientific publications which I have. Hope I make right something at least. Be glad and thankful if somebody will help me figure it out)).

    Great White position

    I am really sore today but it is always a great day when I find a GW because of their rarity in my hunting area. This is a small one at 33 mm. This was jet black on 1st sight, and seems to lighten as time passes. The "shape" of this tooth seems different to me. Does that allow some further insights on tooth position? There used to be some people trying to do tooth position based on shape for Megs, Makos, GWs.... The one on the right below seems to match:
  6. Trying to nail down the evolutionary chain of Carcharodon carcharias and its pretty figured out until you get to the very beginnings... It seems that either Isurolamna inflata or Cretolamna schoutedini are the earliest relatives in the evolutionary development of carcharias, but I'm looking for some expert advice.... I know that Carcharodon plicatilis is rightfully disputed but is included as a reference... Isurolamna inflata ? Macrorhizodus praecursor Carcharodon hastalis Carcharodon plicatilis Carcharodon hubelli Carcharodon ca
  7. It is really difficult to classify these small specimens, so I only put together the ones that I think are more similar. This one is Palaeocarcharodon orientalis for sure.

    A few more shark teeth

    The weather was great today, so I hopped on the bike and headed off to check out a new museum in the area which was supposed to have opened up on April 1st, but I guess it must have been an April Fool's joke because it was closed. Well, actually we got locked down on Monday, so they weren't allowed to open the doors. I was just hoping, and anyway it was a nice day for a ride. It's a small branch of the well-known and much larger Hauff Museum in Holzmaden, so one of these days soon (hopefully), I'll drop in again to have a look around and talk shop with the proprietors. After I'd studied t
  9. This tooth was collected from one of the Monmouth County, NJ, mixed Miocene/Eocene sites. The curved shape makes me want this to be a Parotodus benedeni, but it could just be a weirdo Odontaspis, Carcharias, or one of the other more common types of sharks. Would love to hear what you all think.
  10. Finally ... a short trek on the open prairie of Eastern Colorado and into a slice of the Cretaceous period. This was my first true jaunt since my move from the East coast and it was a welcome change to my normal routine. My journey really began several years ago when I purchased some shark teeth from a fossil forum member in Colorado. He regularly visits a site on private land in Eastern Colorado that contains (what we think) are exposures of the Fox Hills fm. , and are chock full of marine fossils from that time period. I contacted him several weeks after I arrived, desperate to

    Carcharias sp. I believe it is a Carcharias.

    It's a shame this specimen was broken during removal.

  16. Recently I aquired this Carcharodon tooth from Sacaco, Peru whose serrate conditions seems a bit peculiar to me. I can't really decide whether or not this tooth is from a late-stage hubbelli or an early carcharias. The serrations seem to wear/taper off just short of the tip on one side and abruptly end near it on another, and some (although not all) of the serrations appears to be angled in a way, although I suspect some may be due to wear. My thoughts on the serrations keep seesawing in my head. Would this tooth better represent a late-stage hubbelli or a carcharias? T

  19. Hello all, I hope you are having a fossiliferous New Year. To kick ours off, MomAnonymous and I went off to Brownies to check out the beach. It seems I really do need waders as I was unable to round the point even at low tide. We met @sharkdoctor on the point who had found an amazing bird bone in zone 10. We chatted for a bit, and he gave me a lot of information that could prove very helpful, and even invited me to a group hunt at Blue Banks. What a generous man. I get good luck when meeting other collectors! We putted around for a bit, finding some really nice sand tigers at one p

  21. I’m eager for some help identifying this shark tooth fragment I found while beach combing on Hilton Head, SC. I’ve found many, many sand tiger shark teeth here over the years, but this is by far the largest. It’s only a fragment, but the size with the huge nodule on the root is so very different from what I usually find on the beach. Is this indeed from a type of sand tiger shark? I’d love to learn more about it.
  22. Hello guys and gals, I greatly appreciate this forum and thanks for welcoming me. I have a set of 4 teeth that I only know that are from Florida. I’m thinking Carcharias but I’m a noob so I’m not confident. As far as the crinoids, I got them as a “gift” after purchasing a tooth from a dealer. All he knew is they were crinoids from Dakhla, Morocco. I’m guessing Pennsylvanian? Any information would be awesome. Thanks guys/gals
  23. I'm not sure about the classification. This is the tooth in question: Shark tooth from Fiume Mareccchia, Italy I think it's a Prionace cf. glauca, @michele 1937thinks it's a Carcharias acutissima. Who can help? Carcharias acutissima with side cusps Prionace glauca without side cusps I don't think the tooth in question has side cusps, but I am not 100% sure. According to fossilworks, Carcharias acutissima is known from 43.0 to 5.332 Ma. Prionace is known from 5.332 to 0.012 Ma. Fiume Marecchia is Upper Pliocene, Zanclean to Piacenz
