  1. A couple of nice teeth

    I biked off to my favorite Miocene shark tooth site again this afternoon and when I got there there was already a family with 2 young children scratching and sieving away at it. A bit of conversation showed that they were pretty new to it, so I gave them a few tips and gave the kids all the small Carcharias ones I was finding. Eventually they said goodbye and trundled off down the path. It wasn't even a minute after they were gone that I suddenly found a good sized Galeocerdo aduncus, my largest one to date. A couple of pieces were broken off the edges, but I managed to find both of them in the sand and could glue them back on once I got home. Shortly after that, a Hemipristis serra anterior popped out, also in 2 pieces which I could also repair in the end. That was only the second one of this species which I have found there up to now. Needless to say, I was pretty happy to have found them both, despite having to glue them back together. There were also a nice little Carcarhinus priscus and a Carcharias acutissima to top things off. Here they are.
  2. Miocene Shark Teeth

    Found both of these teeth today while out on the Chesapeake Bay. Would’ve come from the Calvert formation. I’m believe the second tooth is a chunk of a small megalodon based on the serrations and root of it, first tooth I am not sure on. Both teeth are approximately 2 1/3 cm. Thank you!
  3. Good evening everyone, I recently did some fossil hunting in the Green Mill Run river in Greenville, NC. The water was pretty low - ankle/shin deep most of the time. I'm pretty new to fossil identification so figured you guys could help me out. Location: Green Mill Run, NC Date: July 2020 Excavation process: Shovel to river bed The first looks like a jaw with teeth indentations. It's about 1.9" (50mm) with brownish coloration. Additional photos below.
  4. Some fossils at the beach

    A couple days ago I spent the day at the Gay Head Cliffs at Martha’s Vineyard. This beach is famous for its vibrantly colored clay cliffs. I did not fossil hunt in the cliffs themselves because as far as I’m concerned it’s a federal offense to even touch the cliffs, but I did find a couple of clams lying along the surf that had eroded out of the cliffs. They’re pretty neat because they’re the first Miocene fossils I’ve ever found. I was hoping to find shark teeth because I had heard they could be found there but at least I found some fossils.
  5. Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!
  6. A new fossil odontocete-related paper is available online: Mariana Viglino; C. Maximiliano Gaetán; José I. Cuitiño; Mónica R. Buono (2020). First Toothless Platanistoid from the Early Miocene of Patagonia: the Golden Age of Diversification of the Odontoceti. Journal of Mammalian Evolution, in press. doi:10.1007/s10914-020-09505-w. Dolgopolis is the first fossil platanistoid known to have relied on suction-feeding rather than raptorial behavior, considering that the xenorophid Inermorostrum and the delphinid Australodelphis are the only extinct odontocetes besides those belonging to Physeteroidea or Ziphiidae that resorted to suction-feeding to capture prey. In retrospect, the feeding behavior of extinct platanistoids wasn't uniform as previously thought, and the description of Dolgopolis on top of so many other extinct platanistoids is another reason why most people don't know that Platanistoidea was once diverse and widespread in the Neogene, only to see its diversity crash to just one genus by the time that humanity came into being.
  7. My boys found this the other day. It does not look like a whale or porpoise vert, I don't think. Before posting a trip report, I was hoping someone could tell me what it is.
  8. Matoaka Beach Gold

    Some of the awesome finds from 2 days worth of hunts at Matoaka Beach. I have no clue what the vertebrae belonged to (I know it’s not a shark). I believe the large bone in the back is whale, just don’t know what part. Lastly, if anyone has any information on what the shark teeth are exactly please let me know. I believe the big one is a mako, the long pointed one may be a lemon, and of course the snag for tooth. If I am incorrect please let me know! Looking forward to going back and finding more!
  9. Hello, I would like to ask for opinions about this 5 mm "tall" gastropod. Its from the Langhian - Miocene (15 Ma old) "Florianer Schichten" of the Styrian Basin in western Styria, Austria (St. Josef, site Fuggaberg-3). Other molluscs at this site are Granulolabium, Terebralia, Anadara, Acanthocardia, tellinid bivalves, oysters, naticids, buccinids etc. Many thanks for your help! Franz Bernhard
  10. Lee Creek finds for ID

    I found these fossils in matrix from the Aurora spoil pile. What kind of shark teeth are these two specimens, please. Can the coral be ID'd? Thanks for looking.
  11. Ok, tired of AK Hiker getting all the glory for Alaska finds hehe Made a run to my local fossil spot yesterday (which includes about 3 miles driving down the beach). Try to only go down when the tide is falling to 1, give more time to explore, and 2, more time to escape when the tides rolls back in. We can have between 8 - 28 feet of tide change! During big high tides the water is to the bluff. Some of the driving is loose sand / gravel so want to make sure if accidentally get stuck have time to get the car dug out before it takes a salt bath! We're searching through the Kenai group, Beluga formation, mid-late Miocene age plants. Most of it is splitting slabs that have been weathered out sitting at bottom of bluff along beach. Most slabs have exposed fossils but they are quickly worn down so it's rock breaking time to find sharper fossils. Most I have not ID'd yet (some I have a very hard time seeing / understanding the differences) First photos are of the area searched (bluff) and the view across Cook Inlet. In 1st one you can see Mt Illiamna across the Inlet which is one of our local dormant volcanoes (3 within 100 miles have erupted in last 30 years or so. Last in 2009)
  12. Squalus occidentalis (Agassiz 1856)

    From the album Pisces

    8 + 12mm. long Miocene Found at Sharktooth Hill, Kern County, California Thanks to Tony (ynot) for these.
  13. Hexanchus andersoni (Jordan 1907)

    From the album Pisces

    3cm. at the base. Miocene Found at Sharktooth Hill, Kern County, California Thanks to Tony (ynot) for this one.
  14. Carcharocles megalodon (Agassiz 1843)

    From the album Pisces

    5cm. at the base. 4cm. high at the tip. Posterior Miocene Found at Sharktooth Hill, Kern County, California Thanks to Tony (ynot) for this one.
  15. Unidentified Rib Fossil Found in Florida Gulf

    This rib bone fragment was found on a Florida beach in Englewood. I believe it belongs to a Dugong, but it’s not solid black like most online examples. It’s roughly 3 inches long and 1 inch wide. Can anyone help affirm my theory or provide evidence to the contrary? Thank you.
  16. Long Cylindrical Shell; Tube Worm?

    Was looking for crabs and clam shells in a Miocene deposit near Centralia WA. Was shocked to see what looked like PVC pipe sticking though a rock that was millions of years old. Tube itself is rather small, only about 2 inches in length, and 0.3 inches in diameter. My best guess is that it's a tube worm's shell. Thoughts?
  17. Micro Fish (?) Tooth

    I found this - almost missed this - while sifting through some micro matrix today. I'm guessing some sort of fish tooth, but can anyone confirm? From Aurora Fossil Museum, Aurora, North Carolina. Lower to middle Miocene from the Pungo River Fm. It's so small that I have a hard time getting the camera to focus and my microscope cam just made it a big, black blob, so I apologize for the soft focus. That course rug it's sitting on is a piece of fine velvet!
  18. Quick Calvert Cliffs Trip

    It's been awhile since I've posted...but the good news is that I've been able to make many trips to Calvert Cliffs since my last post. Yesterday was my most recent trip down. The predicted tide and swell forecast looked good and I had visions of megs dancing in my head during the 2.5 hour trip down. I arrived by 6am and after a nice nature walk I was beach-side by 6:30. The tide was high as it usually is during the summer, but it never really went down at low tide (~11:00). That being said, there was very little beach to search and not much being kicked up. However, it was great weather and I spent about 6 hours enjoying the Chesapeake Bay before I called it a day (I usually stay until 5:00ish, but with no beach to search I decided to skip the traffic jam on 695 that is inevitable between 4:00-7:00). I found about 50 small teeth, some bay glass, half a cookie, and saved a few fish & horse crabs. My find of the day and total trip maker is below. Besides some large (for the area) meg frags, it is my largest tooth to date. I couldn't believe it when I saw it sitting along the high tide line, and even forgot my phone in the water when I examined it after snapping a few pics and filming an uncovering video (thank goodness for waterproof cases). Anyway, below are a few pics as found, unearthed, and dried. Although I didn't score any megs, it was a great day to enjoy nature by myself without seeing another person other than a family on a boat that anchored and was enjoying the bay themselves. Any help on ID and scarcity would be great. I'm thinking either lower isurus oxyrinchus/desori (mako), carcharodon hastalis, or possibly carcharodon plicatilis. The exposed formations at this location are Calvert and Choptank, with possible wash from St. Marys.
  19. SMALL teeth but not micro

    I have recently found dugong, whale, and dolphin ribs. Hunting friend gave me a tiny rib that we both thought might be dolphin. He is NOT a bone collector. I found a small dolphin tooth. It is 13mm. How small do these get? and then a predator tooth. I will just leave the photos, and request comments and identifications.
  20. Miocene Humerus

    Fossilized 1/2 bone, 4.5 inches, Seems to be a humerus. Searching the internet, I came across this photo of a much larger complete humerus. What do you think?
  21. Mystery Vert, Calvert Cliffs

    Hi all, I found this strange vertebra today in a small creek that flows into the Chesapeake Bay. If it's a fossil, it is from the Calvert Formation. It's unlike anything I've seen before, and certainly not a cetacean vert, so that begs the question: what is it? I have not done the burn test on it yet to confirm it as a fossil, but can anyone identify it based on morphology? I believe it to be from a large terrestrial animal, but I'd like an expert/experienced opinion. Thank you in advance!
  22. Is this an osteoderm?

    I found this at Matoaka Beach (Miocene exposure) in Maryland the other day. Does this look like an osteoderm, or something else? Thanks for your help!
  23. Are these coprolites?

    Hi all, I recently found the items below at Calvert Cliffs State Park (A-F) and Matoaka Beach (G-I) in Maryland (both Miocene exposures). Image scales are in inches. I'm not sure what these are. Could some or all of them be coprolites? If so, any ideas as to what kinds of animals they came from? Thanks for your help!
  24. Is this another denticle?

    I could use some help with the ID of this ornate little find from the Cookie Cutter matrix from Florida. I have considered ray tooth and shark or ray dermal denticles...@Al Dente @MarcoSr Thanks for looking.
  25. Could these be Calippus teeth?

    Through the years I've found these very small horse teeth in SE Texas. In the photo the 2 center teeth are each 16 mm wide as measured across the width of the crown, the rightmost tooth 19 mm. I know these pre-equus teeth can be difficult to ID. Anyone out there can help? @Harry Pristis @Shellseeker @garyc
