  1. Hello everyone, I have gotten really into meg diving this last year to the point where I am driving down to Venice from Orlando twice a month to dive for teeth. I have started to look into getting black water diving and I am not really sure where to start. Does anyone have any rivers that are good for black water diving? I have heard talk that people do it in the Peace river and the St. Marys and I didn't know if that is where most people go or if there are other rivers people dive that hold a good amount of teeth. I don't want to sound like the guy who is asking for y

    Isurus retroflexus

    Isurus retroflexus is from the Miocene-Pliocene epochs. While the vast majority of what I find in this particular location is Miocene-Pliocene in age and is likely to have come from the Goose Creek Limestone formation (early-mid Pliocene), we can't rule out the possibility that it came from an overlying lag deposit called the Ten Mile Hill Formation. The Ten Mile Hill Formation is mid-Pleistocene and can be found overlying older formations in the area. Since Miocene-Pliocene fossils have been found in the base of the Ten Mile Hill Formation and this tooth was ex-situ, the formation is undet
  3. Return to the Badlands of North Texas At long last, rain graced the lands of North Texas this past week. For many of us, that meant it was time to finally crawl out of bed and beat the crowd to that one particular site desperately needing a refresh. In my case, I set on my way to explore a newer spot in the Grayson Marl while the ground was still nice and muddy. I'd been to this place once before, but it had already been thoroughly picked over. It's a popular site, but even then, it managed to pull through and produce some fine specimens for me to take home. With that in mind, I su

    Two thresher teeth for ID

    I have two teeth that I found previously somewhere in the Summerville area and stuck in a riker mount. Looking through them today, I noticed one that I did not recognize. In comparing it to others in the mount, I noticed another one that has similar enamel on the root (labial side), although the root is much more curved overall. Can anyone help with these? My areas are heavily Oligocene but some have either an overlying Pliocene formation or Pleistocene lag deposit that produces some megs, great whites, etc. Tooth 1: * 14 mm slant height x 14 mm across * Root is very
  8. I acquired some Paleogene fossil shark teeth from a Ukrainian fossil hunter/collector and was wondering if anyone here might know what formations these may have come from. They were found on an island in the Dnieper River near/just south of Kyiv. The collector didn't know the specific formation and described them as coming from sand alluvium. From what I can tell, these appear to all be Eocene species, though not being familiar with the local geology, I can't rule out Paleocene for the Otodus obliquus tooth at least. Any ID corrections are of course welcome as well! Otodus obliquus

    Andalusia, AL teeth

    Hello! I found these two teeth while fossil hunting at Point A Dam in Andalusia, AL and noticed that at least one appeared to be more reptilian than shark. Sizes are ~1 cm each Though it was hard to get a decent image, this tooth is extremely flat. This tooth is very round, which led me to believe it may not be a shark’s tooth. Thank you for your time!

    Shark Teeth from Post Oak Creek

    I’d like for my Post Oak Creek collection identified (specifically the shark teeth), but I can’t find much information online about the species of shark whose teeth are found here (Post Oak Creek in Sherman, Texas). When I HAVE come across general information about the creek and other peoples findings online, there aren’t any pictures of the teeth or nobody else knows exactly what they have. It’s also hard to tell if I’m grouping them correctly, so I apologize if I’m mixing some species together. The longer teeth have very similar characteristics, but greatly differ in size. And the only teeth
  11. Over the month of December, I've gotten the opportunity to check out several sites across the state of Texas. In my fossil interests, I have to admit that I am certainly a bit vertebrate-centric, but that does not mean I will pass up the chance to marvel at a beautiful invertebrate specimen when given the chance. For better or worse, these past four mini hunts have not really delivered on the vertebrate end, but have made up the difference in terms of inverts. I've decided to combine these smaller hunts into one report. For those with invertebrate addictions, I hope this sampler of Texas fossi

    Help with Dogfish identification

    We just got back from the Denver show, and while we were there we picked up this really nice fish fossil plate from Lebanon. What makes it special is that one of the 3 fish is supposedly a Dogfish. Unfortunately, we didn't get much other information from the dealer, so I'm hoping someone here can help us out with a few questions: 1. Any idea what species this dogfish is, and is this technically a shark or is it a relative of a shark? 2. Any idea what the age would be? Thanks! -Brian
  14. I found this tooth while dissolving a rock from Mishash formation (in southern Israel). Some suggested that it might be a nurse shark tooth or a cat shark tooth. Could you please help me figure it out? And if you know the specific species it would be great!
  15. Not a true fossil hunting trip, but a hunt for an identification. In July last year, a saw a listing on online auction site for a fossil "shark/fish". I do not often make purchases on auction sites, as quite frankly I never see anything really cool, but I do look from time to time as I suspect many of us do. Something about the specimen caught my attention, but I was not certain based on the poor pics or info from the seller what the specimen was. I did email and asked some questions, with the response, "I bought it from an estate sale and have no idea what it is". I kept watc

    catticus

    Sawmill Branch contains fossils from more than one formation and epoch, but everything I find online says C. catticus in Summerville come from the Chandler Bridge Formation (upper Oligocene).

  17. Well, it's taken me a lot longer than I thought it would to write the second part of this trip report, mostly because I've been busy with school and several trips to other places across Texas collecting fossils, but also because I must have made about nine trips to the particular Eagle Ford formation creek site I wrote about in the first post. I've got a lot I could say, but I'll narrow it down to just the most exciting finds - I've still got another trip report covering two trips I took to Jacksboro/Mineral Wells and Post Oak Creek to write as soon as I'm done with this one! I'll

  19. Goodday Im considering this nice Indonesian Megalodon Tooth, as I got a few in my collection, im looking for one with an authentic root. Sometimes you see these and spot something off immediately , with the color or shape or the root. This one looks quite good. The sellers says its 100% authentic, with only one small fill in the blade blackside. Any shark experts opinions about it? file.mp4

    Shark Tooth ID

    We picked up a fossilized shark tooth at Blouberg Beach in Cape Town, South Africa, and would appreciate if someone could help us ID the shark it belongs to. It's 4cm long and 3.5cm wide.

    Tooth or rock?

    Is it possible this is a weird shark/megaladon tooth? Chances are it’s just an uncannily shaped rock, but I’m wondering what other views are, or whether it’s even possible for them to be completely rock like this? Found this on the beach in Perth Australia (have no ruler with me but roughly 3cm in length, 2.5 wide and maybe 1.8 cm depth)
