  1. Shark tooth? North Carolina

    I found this tooth (same tooth, two sides) in some phosphate mine slag from the Aurora Fossil Museum. Can you tell what species this is? I don't see anything quite like it on the charts I've consulted. The other pic is from the same slag and is some kind of ray, I believe.
  2. Help with shark tooth

    Hi all. I need help with this shark tooth. It comes from an European Lutetian. After doing some research, I have found the genus Macrorhizodus as a possible candidate, but my knowledge of these critters is very limited. Can someone help me? Thanks in advance
  3. Modern Posterior Great White Shark Tooth

    From the album Sharks

    Modern reference for a posterior C. carcharias. NB: No bourlette, large and irregular serrations. cf. http://phatfossils.com/extant references/Carcharodon carcharias (Great White Shark).php
  4. ID help on Shark Tooth

    I thought at first it might have been a small lower hemi but the more I looked at pictures, it also looked like it could be a symphyseal tooth. It is hard to see in the pictures but there are faint serrations on the tooth closer to the root. This was found near the Scientist Cliffs area of Calvert Cliffs. Thank you in advance!

  6. Rock Hunting Franklin NC

    Hey Fam! Going to be in Franklin, NC for a few days in October. I’m fixin to do as much rockhounding as possible which I believe goes without saying. I’m looking for resources in the form of Areas where I can sift, walk river banks and what mines (I probably only want to spend money on one) are worth the time devotion to. My parent’s place is on a mountain which is full of creeks. Am I bound to find some neat stuff just hopping from one to another? What can I expect? Any information is greatly appreciated!!! Edit: I grabbed a UV light off Amazon because I’m told Rubies and Garnets Fluoresce at night.
  7. Shark tooth ID help

    Can anyone ID this shark tooth? Found in Charleston, SC.
  8. So Sir David Attenborough finds a shark tooth in Malta in the 1960's. He gives it to a seven year old recently and now the Maltese government wants it back. Maybe they can trade for the falcon? LINK to ARTICLE
  9. Shark Tooth ID Help Needed

    Hi! I found this shark tooth at Clam Pass in Naples, FL yesterday. I've only found two other super tiny teeth on the beach here during my 20+ years of living here... so I was pretty thrilled to find this one. Can anyone help me ID it? Thanks so much!
  10. Paratodus benedeni tooth?

    Two weeks ago I have found this tooth in the lower miocene deposits of southern Slovakia. Scale is in cm. Is this the Paratodus benedeni tooth? Thank you in advance.
  11. River worn or digested?

    Hi all, I was wondering if anyone could help me with this tooth... first, I was wondering if anyone could I.D it, it appears to have a cusp, so I’d say no to megalodon, so I’d guess either an Angustidens or Auriculatus... second, I was wondering if you guys think this is just a worn tooth that was in the river for a while, or if it was digested, I saw one for sale that looked similar and said it was digested, so it got me wondering, and I figured it was worth it to at least check on the forum. TIA!
  12. Odd Little Lee Creek Tooth

    I found this tooth in a bucket of matrix yesterday. It has the hint of cusplets on each shoulder and this kind of throws me. I have my own impression of the I.D. of this tooth but am looking for other opinions. I have thousands of Lee Creek teeth in my collection and have gone through countless gallons of matrix, but this tooth just looks odd to me. Any thoughts or suggestions are appreciated.
  13. Shark Teeth ID

    Friend of mine gifted me some shark teeth. He's not a fossil hunter, nor that much into fossils; they were given to him. I know they're from the United States, but beyond that I don't have a locality. This one is 3/4". My first instinct here is to say Lemon, but the base of the blade along the root is serrated. Bronze Whaler?
  14. I finally found a full Meg in Charleston, SC! It isn’t huge (probably about 2.5-3 inches or so), but it was nice to finally find one!
  15. Benedeni

    I bought some shark teeth from South Carolina recently, including the one below. This is a Parotodus benedeni, right? The tooth measures 1.59" slant height.
  16. Shark tooth with matrix?

    Hey, I was wondering what is attached to the root of this tooth... it’s not root, and it’s weird placement for matrix, could it be a little bit of the jaw still attached, like cartilage? I’m pretty sure it’s Carcharhinus, but if anyone could confirm, I’d really appreciate it! TIA!
  17. I have here a Meg from Florida. Does it look like it has any repairs or restorations done to it?
  18. Is This A Crab Claw?

    Does anyone know what this is? I am thinking, perhaps, it is a piece of a stone crab claw? Someone mentioned shark tooth. Found at Quintana Beach, Texas; Gulf of Mexico ocean, two days after two hurricanes hit landfall.
  19. Mako shark tooth on matrix

    From the album Fossil collection

  20. Small posterior shark tooth

    Hey, I purchased this sometime in October, November, or December of 2019 and was wondering what you guys thought it was. It’s 1/2 an inch wide and 3/8 an inch long, to me, it looks like a posterior megalodon tooth, but I don’t even know if the get that small, there might be serrations, but the tooth is extremely worn, so it could just be feeding damage. TIA
  21. I have here a Megalodon that the seller claims is found in the Philippines. I'm requesting more information, but none is provided. As far as I know these teeth are rare, and it doesn't seem to me that this preservation is of the Philippines. I'd like some more opinions on this please. Edit: I received provenance from the seller, who contacted the supplier for it. The claim is that this Megalodon tooth was found in Sarangani Island, Mindanao, on the beach. I found a geological map of the Island via http://portal.onegeology.org/OnegeologyGlobal/: The formation of Sarangani (the island to the right, despite what this map says) is noted to be "Upper Miocene-Pliocene." Thus, the formation dates back to 11.6 million years, to 2.58 million years at its youngest, and appears to coincide with Megalodon. The part I'm less certain about is the preservation. I'm thankful that the map describes some of the details of that, namely, "Largely marine clastics (molasse) overlain by extensive, locally transgressive pyroclastics (chiefly tuff, tuffites) and tuffaceous sedimentary rocks." I'm wondering if these elements explain the preservation of the tooth I'm looking at.
  22. I have a Megalodon tooth being sold; the seller claims it's from Morocco. I have serious doubts based on the coloration and preservation. To me, it looks more like a North Carolina Ledge tooth. I'd love some more input, please.
  23. Hi all, Recently I was collecting at a locality that exposes the Duquesne Limestone and shale, which if you’ve seen any of my previous posts you’ll know that I’ve collected extensively. But for those of you that have not, the Duquesne shale is a layer of black, carbonaceous shale found in areas where the Conemaugh group is exposed. This layer is chalk full of disarticulated vertebrate remains, but some of the most recognizable are the teeth of Orthacanthus and Xenacanthus. These were eel-like sharks that existed from the Devonian-Triassic and had bicuspid or tricuspid teeth. They grew to be about 10-12 feet at the largest and thrived in the swampy lakes of the late Pennsylvanian. It’s somewhat uncommon for me to find a large Orthacanthus tooth (which are tiny compared to Otodus sp. )and it is even rarer for me to find a tooth with feeding damage. It seems to me that, understandably, many collectors of Cenozoic shark teeth are disappointed when they find shark teeth with feeding damage, but for me at least when I find Paleozoic shark teeth with feeding damage it makes it even more special. Last time I was collecting I did just that. Interestingly enough this Orthacanthus compressus tooth is my largest yet and has a very unusual break. The cusp that is missing is not broken cleanly at the enamel, rather, when it broke off it took a good chunk of the rooth with it. To me at least this would indicate that the shark was using quite a bit of force when it bit down, and whatever it bit in to must have been very hard and made for a painful meal for the shark. It’s important to note that the other cusp was damaged recently and isn’t feeding damage. I’m not one to heavily speculate but I’d imagine that it had to have bit in to one of the heavily armored Paleoniscoids for damage of this nature to take place. Or, who knows, the tooth might have just been old. Whatever happened to break the cusp is lost to time, I guess. Regardless, I think it’s a wonderful find and reminds me that these animals were truly alive and had imperfections. Hopefully you all find this as interesting as I do .
  24. Shark Tooth ID Help

    Hi. Hope everyone had a great week. I found this tooth this morning as I continue to go through more of the Lee Creek Matrix. I am somewhat confident that this is a Finetooth shark - Carcharhinus Isodon. I wondering if someone can confirm if I am correct on this one. Thank you so much for any feedback.
