  1. I think I know the species of these teeth, but they have strange features, and I wonder if they are pathological or (para)symphyseal. G — I think this is a giant thresher tooth. However, it seems unusual in having a cusplet-like fold of enamel on one shoulder (marked by the red asterisks). From Morris Island, SC USA H — O. angustidens, one cusplet appears typical but one is very muted. Root is also relatively tall. From Morris Island, SC USA. I — Similar to H... O. angustidens, one cusplet appears typical but one is very muted. Some enamel damage, but I don't think it extends over the "muted" cusplet. From Summerville, SC USA.
  2. Since posting my last trip report (below), I've gotten back out twice. I have a handful of spots and am still figuring out how much they produce (if I can go on a weekly basis and still find stuff). Since I drive about 2 hrs each way, I always hope to find one good "trip maker" each week, but who doesn't? But, I was having a pretty good string of luck lately and, being a novice with limited sites, knew it had to come to an end. Last week seemed like it was going to be it. My spots weren't recovering quickly enough and I was either finding little stuff, or broken/worn teeth. It was looking like these were going to be the best I could do (which is funny because I would have been thrilled to find these 4 months ago): I decided to try out two new spots, one of which was a very bad idea in the heat. I came across this guy, which did not make me feel any better about the spot: It definitely was not the honey hole that I had been expecting, so I went on to another spot. Found a decent amount of small teeth and ray mouth parts until it was time to leave. And then, walking back in the creek, I looked down and saw what I thought was just a broken angustidens. But, no, this broken, worn tooth was my find of the day/week because it was my first identifiable meg frag! It's small (for a meg), it's broken, but that was what I had been waiting for! (Also found my first tuna hypural bone, which is cool.) So, after finding a meg last week, I had already accepted that yesterday would be the day of disappointment. Other than to find a complete meg, how could I top last week? Sites seemed to not be producing much, but I found a small angy that I decided would have to be my find of the day: Had one spot left to hit when the storm started to roll in, but I was determined to get there and look quickly (2 mile hike for this spot). I literally had about 10 minutes in the spot before the sky turned too dark to see much but, what did I see? This!! Something that actually did top my small, broken meg! I decided to make a run for it after that, and made it back to my truck right before the downpour. So, here I am again knowing that I will soon have a disappointing hunt.
  3. I know that tooth shape depends on where it is located in the sharks jaw. When looking closely at the teeth I noticed not just different blade characteristics, but also differences in the root and cusps. On the larger tooth the cusps are much less pronounced. As for the roots, one has a “u” shape and the other a “v” shape. My intuition tells me they are from different stages of evolution of the Angustidens shark, but I don’t know. Are thes differences just a result of the size of shark and tooth position?

    Cusps of mega-toothed shark

    We should all agree that the side cusps of these shark gradually disappeared with evolution, but how did they deform in the process of shrinking and disappearing ? Does the cusps’s tip gradually move closer to the middle crown and fuse together? Just like the two teeth in the picture below, is the brown specimen older than the other?

    Carcharocles angustidens

    It’s about 1.875 inches long in the longest side,and the seller said it was found in Chandler Bridge Formation. So I guess it’s angustidens?
  6. Hi all, I wanted to share a couple nice angustidens teeth I found this week hunting in Charleston, SC. Not the biggest, but I love the colors on these two so I wanted to share. Happy hunting everyone!
  7. Hey all I came across these 3 shark teeth today and I believe they're all in the Odontidae family. Even though they all have cusplets, the size of these teeth rule out juvenile O. megalodon teeth so they must belong to a shark earlier than O. megalodon and the question I have is, what species? I can have a couple of guesses after looking at a lot of different photos of O. angustidens, O. chubutensis, O. auriculatus (I'm doubting it's O. sokolovi) teeth though google, through dealers etc but I'm also a little confused because some I'd think are one species and they're labeled as another. I do think I've come across something a little special in all 3 of these teeth though, even though their condition is a little rough. Any help pinning down a species would be awesome! Also, are they rare (as far as fossil shark teeth go)? They aren't something I've ever come across for sale anywhere in my country, let alone seen in the flesh but I did recognise their family. Sorry about the quantity of pictures, I'd rather be too thorough to get all the detail possible The last pics is a shark tooth family photo, (I should have added my Palaeocarcharodon teeth) just for the fun of it!

    Megatooth Sharks

    From the album: Sketches

    The meg is from the Miocene in Wrightsville, N.Carolina. The angustidens from the Oligocene in S.Carolina. The obliquus from the Eocene in Qued Zem, Khouribga, Morocco.

    Odd shark tooth

    Hi y'all. Need some help with this tooth I picked up at a local rock shop. At first I thought angustidens, but it seemed different. I'm guessing it came from the Carolinas or at least the East coast. It was associated with other megs, angustidens, and makos that I recognized as having Carolinas-type preservation, maybe Florida. The root is very flat and the crown narrow, making it look more like a mako lateral. It has virtually no bourlette, wrinkling/striations at the foot of the crown, and maybe cusplets judging by the bunching of the serrations. It's a lateral tooth, but looks different from the angustidens and auriculatus teeth I've seen. It could be slightly pathologic. @MarcoSr@Al Dente

    Shark Teeth

    This time I decided to draw some teeth from the group of Megatooth sharks. No point in showing original photos this time, since you all know what they look like. Now that the weather is finally taking a turn for the better, I'll be spending more time in the field again, so it may be a while before I get back to sketching again. And besides, Sara has just arrived and I need to keep her entertained.
  11. I have here four shark teeth, 1" - 1.5" each. They were found in the Southeastern United States. I have no locality more specific than that. I think they're Angustidens or Auriculatus, but I can't really differentiate between these. Could anyone kindly help me identify them? I'd also appreciate if someone can nail the locality down based on the preservation. It's chalky, but the colors of the more orange ones don't really match Bone Valley. Might it be a South Carolina landsite? Thank you, Bellamy 1 2 3 4
  12. Our favorite South Carolina paleontologist @Boessegot in the news (again) for finding a mega shark nursery. https://www.sciencealert.com/a-24-million-year-old-megashark-nursery-discovered-in-south-carolina
  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 !

    Shark tooth ID

    Hi guys I have an angustidens tooth (on the left) and a Chubutensis Tooth (on the right) I am finding it hard to separate the 2 as different species as they look very similar, the only difference I notice is the roots are different, are there any key factors to look out for with identifying the 2. Thanks

    First chub tooth

    Hey guys I purchased my first ever Chubutensis tooth a love it! I don’t no a lot about the species and would like to know more, this chub tooth has big side cusp and would like to know if it’s a transition tooth or just how this tooth is as it’s quite large (7cm width 9cm length) thanks
