    On a Roll with Ears?

    Found this bone over a week ago. When I pulled it up out of the river I wasn't sure it was even a bone. I did think it had enough interesting features to take it home and investigate further. After soaking and softening up sand and pebbles lodged in small openings I was able to clean it up a bit. At that point I started to see characteristics that made it look like another ear bone. A search of the web turned up what looks like a good comparison from the Charleston Museum website. They have a photo of an "undescribed mysticete cetacean" whale ear bone, an auditory bulla (object ID: PV243

    Another ear ID

    Picked up another inner ear bone last week that looks to me like it could be another parietobalaena, (baleen whale). I have had the good fortune to have two Id'd by @Boesse. One in 2019 and one just last month. In comparing it to the 2019 find I think it is a match. I am hoping the good Doctor has the time to provide an ID on this one. If anyone else has an idea as to an ID their input would be appreciated. Thanks! First up the 2019 find: Now the latest, found last week. It measures - 40mm x 37mm x 29
  3. A while back I found a concretion containing some rather large teeth. The area was a mid-Miocene coastal deposit here on the South Island of New Zealand. These were my largest teeth yet so I was rather excited, tempered a bit by the fact that it was in a very, veeery hard concretion. I got in contact with Dr Joseph Bevitt at ANSTO where they had a nuclear reactor and are able to do neutron scanning. The instrument is called the Dingo: https://www.ansto.gov.au/our-facilities/australian-centre-for-neutron-scattering/neutron-scattering-instruments/dingo Neutron scanning is needed as

    Calvert Cliffs Multi Trip Finds

    These are from multiple trips between 2022-2023. all from Calvert cliffs, each trip has something unique I would like assistance in identifying so for convenience's sake, I will refer to the items in alphabetical order relative to the numerical trip order. 1A 2B etc. Trip 1 1A pretty sure it is a crocodile tooth, Thecachampsa sp? 1B this is a bone that i found on the beach, im not sure if it's a cetacean atlas or skull fragment. but it's got this weird hole in it on one side. 1C clearly a ce
  5. Found land site. Wondering if it's possible to tell the species of whale? Thanks!

    Seeking Help With ID

    Finally able to get back out on the Peace River, FL after the flooding has started to subside. Hunting with a friend earlier in the week and he came up with what I think is a caudal vertebra. Looking at numerous photos on line and in reference materials that is the closest I can come to an ID. Based on size I am thinking large mammal or whale. I'm not sure there is even enough of it left to allow for an ID. Any help would be greatly appreciated. The specimen measures 3 3/8th" wide x 3 1/2" long x 1 7/8th" tall.

    Cetacean tooth fragment?

    Here we go again! found in the same conglomerate facies of the Vaqueros is this weird tooth(?). To be honest I’m not even sure its tooth, could be a small piece of bone. BUT it does have an distinct piece of enamel(?) near one of the tips. Unfortunately rarely any teeth here have been found whole. But I will keep looking! hoping you people with more experience can help solve another mystery!
  8. I have found a few gator teeth in the past, but they have all just had a slight curve. Found one yesterday that curves up and to the side. Is this pathological, is it normal and I just typically don't see that much root, or could it be a croc? I know there is currently only one crocodilian native to South Carolina, and that is Alligator mississippiensis, but I can't find anything saying if there were crocs here in the Oligocene or Miocene, which is mainly what I find represented in this creek. It has two carinae, which I believe could mean gator or croc. I read that croc is more curved tha

    Cetacean vert?

    Found this in the water near the fossil beach of Westmoreland State Park in Va. Seems like a whale / dolphin bone, but what part? Is it a vert piece? As always, thanks for the help.
  10. Hello everyone. I'm making my rounds across my different groups and forums, so if anyone has seen these photos before you'll have to suffer through them again. From June through the end of August I locked in on a concentrated area of sand tigers, makos, and my favorite mega-tooth shark: Otodus auriculatus. I didn't find one every trip out, but my most plentiful day gifted me 3, and my last trip out provided me with the largest tooth I have ever recovered from the garden state. I battled minuscule mosquitoes and a horsefly that was every bit horse as it was fly. Despite nature's bes

    Need confirmation on what this is

    Was at flag ponds today looking for fossils in the Calvert formation. This looks like a cetacean rib fragment? Dolphin/porpoise? Thanks all.

    Cetacean tooth

  13. So went back to the dry dig site today, hoping to find a 3”+ Meg. Did not find one. Did find 3 Megs, all under 2” though. And loooots of whale stuff. Tooth, ear bones, small verts. Also found some great Hemis, some horse teeth (3-toed? Pre-Equus? Not sure). Anyway, here we go: To start off, the Megs and Frags, happy with the complete Megs today, despite being small: Now all the Whale stuff! Tooth, ~3”, which is super cool: 2 ear bones: Allllll the bits of verts: Next up, the massive chunks of tur
  14. Here are my best guesses on the sharks teeth (1st 9 pics): (1) Hemipristis serra uppers pretty sure (2) all gray sharks? (3) tiger? (4) and (6) lemon/lower gray/others? (5) tiger-like? (7) ray (8) ??? (9) & (10) may include a major and lower snaggletooth but mostly stumped (11) most sand tiger with maybe a lower snaggletooth? (12) upper great white and 2nd is maybe an upper narrow or giant white because no serrations? (13) may not be able t

    Tooth ID help!

    Found this tooth yesterday. I was thinking it could be dire wolf based on the root, just looks similar to a canine i found and the nutrient groove. But then the surface of the tooth isn't smooth, feels rough-ish so then was thinking cetacean maybe. Found in sarasota county. Any help is appreciated, thank you!! Pictures attached

    Basilosaurus or Pakicetus?

    Greetings! I spotted this pair of Moroccan cetacean teeth for sale online. They are both labelled as being "Basilosaurus", which is likely the case for the thinner incisor , but I'm not so sure about the other, darker tooth. I'm thinking possibly Pakicetus due to the shape of the crown and the dual root. Probably a "cheek tooth" Thoughts? As for quality, the incisor looks probably frankensteined, Thoughts? Thanks for any assistance!
  17. Got back to the Peace River Fl yesterday. When I set off in the kayak at 0820 am it was breezy and a chilly 53* F. The wetsuit was definitely needed if I was going to stand in the river all day. The water was crystal clear and with the sun out it made for a beautiful day. I took some photos after the sun had risen enough to clear the overhanging trees and light up the water. I got back to the gravel bed I have been working on my last few visits and found it undisturbed. Its not off the beaten path and with the water so clear I had feared others might have not
  18. Hello, I recently found this specimen on the California coast near Malibu. I was hoping someone could identify it for me. Thanks for your time!
  19. So, I found these 5 bones, and firstly, I need to know if they are cetacean or not. If not cetacean, then they are likely crocodilian, mosasaur, or I guess possibly turtle. They come from North Carolina, either from marine Cretaceous Black Creek group deposits, or there is a chance they could be marine Pliocene (hence why I would like to either confirm or rule out cetacean if possible). The area they come from is mostly Cretaceous, but I have found a few Pliocene shark teeth there, and stratigraphic maps show nearby Pliocene stratum, so I’m not totally sure (the area is in Cretaceous stratum o
  20. I feel like the larger is a cetacean, turtle, or *possibly* mosasaur? The little one I really have no clue.

    Rooted Dolphin/Cetacean Tooth?

    Hello everyone I found this small tooth yesterday diving in a SE US river spot that has only produced Miocene era materials so far: Shark Teeth-Megalodon, Carcharadon Hastalis (no Carcharadon Carcharias yet), Hemipristis Serra, etc.) and plenty of whale bone, verts, ear bones and teeth. I think this is a small dolphin tooth but I haven't seen one with a root that is pretty much perpendicular to the tooth like this. I've also attached a couple pics of the other stuff found yesterday for reference. Thanks for looking. Let me know if there is another angle that may help
  22. Hi All, It's been a while since I have posted, let alone gone collecting but I just had a really good trip down to the Matoaka Beach Cabins in St. Leonard, MD. Here you can pay $5 ($10 on weekends) to access their beach which gives you about 1/3 of a mile to explore. I went down on Tuesday the 14th since I had some time off from work. It coincided with an extremely slack tide which directly led to many of my best finds. No shark teeth unfortunately, except for two pieces that were just roots with the toothy part broken off. I did however clean up on Ecphora sp. and Cetacean bo
  23. Hello everyone I've got a collection of some random mammal (probably) bone/teeth IDs that I'm stumped on. The brown ones are from a southeast US river and the black ones are from dredge spoils from a different southeast US river. Both produce beat up isolated cetacean bones, ice age mammal bones and shark teeth. I find bones and teeth from the Miocene to modern. I always enjoy seeing what others find and try to guess what they are. Any guesses would be appreciated. Trying to get better at ID'ing fossils found out on trips and am curious how close I am.
  24. BBC article here: https://www.bbc.com/news/world-middle-east-58340807 Academic article here (including co-authorship by our own @Boesse): https://royalsocietypublishing.org/doi/10.1098/rspb.2021.1368
  25. Good day everyone, I was given this cetacean vertebrae by a local who combs the beach for fossils everyday, could anyone potentially identify it - it is pretty roughed up. Thank you.
