  1. Sonickmonx

    Dolphin Atlas

    From the album: Sonickmonx's South Carolina Finds

    Found out of the Oligocene Chandler Bridge Formation. Very pleased to find it in such incredible condition.

    Vertebra or fossil ID

    i found this possible atlas vertebra this morning, on a beach in Ballinskelligs, Kerry, on the West coast of Ireland. I would appreciate it if anyone could have a stab at identification. I think its some sort of whale, but I've no idea how old or what type. Many Thanks.
  3. Hello everyone, I’m new here, nice to meet you! I recently acquired a few boxes of what looks like dinosaur material. From the Atlas of Morocco (apparently from Wawmda, Tillouguit formation). So, possibly Atlasaurus? As you can see, the quality is very poor, with a lot of bones only being the inside of the bone (see cell structure) and with a ton of matrix on it. I’ve been trying to determine what is what, before putting the effort in removing the matrix. The first 4 pics are clearly 2 and a bit (caudal) vertebrae. Pic 5 and 6 looks like a partial scapula. Pics 7, 8, 9 are huge and flat (and weigh a ton, like 15 kilos each) so look like (dorsal) vertebrae discs? There is almost no information, neither a lot of research online. If anyone knows about these and could help confirm or identify, this would be greatly appreciated! Thank you for your time. Have a great day!
  4. AroHed

    Bone Fragment

    I found this in one of the creeks (bayou) here in southwest Mississippi. I have found a number of mastodon parts in the same. The most noticeable feature is a curved channel, much like that of a tooth canal. Does anyone know what part of what beast if might have belonged to? Thanks in advance.
  5. Day One ; Locality Three. Midelt 19th February 2019 The Berber nomads are hospitable, generous and very tough : The snow disappears soon after you get onto the High Plains between the Middle and High Atlas ranges. Here are the High Atlas looming in the distance : As one approaches the town of Midelt, the layered geology of what is mostly Dogger, the old name for the Middle Jurassic, still used here, becomes clear : Midelt is full of fossil shops, however most of the fossils, including a kazillion trilobites, actually come from elsewhere. Jurassic ammonites may be from here, and many of the small cut and polished ammonites are from around here, but Midelt is most famous for its minerals, vanadinite especially. Also lead ores, barite and flourite. Top Tip : Don't buy fossils in Midelt unless it's a cut and polished small ammonite you want. Minerals, yes, many are beautiful and very cheap. Hmm, this looks interesting................. "Stop the car!"

    Vertebrate? ID: Cattle or Bison

    Found this in the bottom of a river bank the other day and was wondering what it was. It was buried pretty deep in the bank, but the river has moved a lot in the past decade and had been grazed by cattle since the 1930s. Watonwan River. Cottonwood County, Minnesota
  9. Hi everyone, I have a theropod teeth that I need help identifying. This tooth first came from a reseller from Morocco in 2019 (before Talsint teeth flooded the market). He promises this came from a Boulmane digger, and calls it a Jurassic tooth. Irregardless of whether this is a Jurassic tooth or not, the reseller is reliable when it comes to locality I have tried identifying this tooth but all my best guess is that it's a Megalosauridae indet. Here are its info: CH: 26.1 mm CBL: 13.7 mm CBW: 8 mm Distal denticle count: 13/5mm on mid line Mesial denticle count: 17.5/5mm on mid line Unique trait 1: Well visible transverse undulations Unique trait 2: Mesial carina ends well above the cervix. Even accounting for the worn tip, it's half the length of the distal carina Unique trait 3: Distal denticles significantly larger than mesial ones (DSDI > 1.2) I read "The distribution of dental features in non-avian theropod dinosaurs: Taxonomic potential, degree of homoplasy, and major evolutionary trends" but I am still unable to confidently assign a theropod family to this tooth. The lack of locality data from Boulmane further hurts the ID. Here are some of the relevant pages I highlighted from the paper: Regarding denticle size: Regarding the mesial carina terminating above the cervix: Regarding the transverse undulations: A compilation of features about my tooth and the potential IDs for it: If you have any insight regarding my tooth, I would love to hear it. Thank you

  11. Hi! I can get this incredible and rare tooth. It is from the Atlas Mountains, Morocco so it’s a Jurassic tooth. Any idea about posible ID? Thank you so much!
  12. Hello! I see these spikes from Atlas mountains. I read about stegosaurus (Adratiklit boulahfa) in this formation. Could be a stegosaurus thagomizer? Thank you so much!
  13. I was hunting in a predominately marine fossil location, finding only small shark teeth. After a couple of hours, I suddenly found larger bones, (ribs, jaw??) and then a piece of coral, and then this non-rock... 9 by 12 inches !!! and either Atlas or Axis Vertebrae!!!! I had a feeling that it was whale !!! (thinking teeth) but not sure.. Any day with a great whale fossil is a great trip!!! I scrambled to dig 4-5 more sieves, but just found more small shark teeth... RATS !!!! On the way home, I managed to search images of Whale Atlas and Axis verts, and determined that this one is an Atlas vert from a baleen whale. I wondered about the size of a whale that has a 12 inch Atlas vert!!!! This is amazingly well preserved... Here are a couple more Atlas verts... one that is supposedly a juvenile sperm whale, and another from Aurora dolphins... I am surprised that dolphins (with teeth) have an atlas vert very similar to Baleen whales. Let's see what @Boesse thinks about similarities and differences in whale verts..
  14. DdWhat bone is this? It looks like the vertebra that attaches to the skull, which I thought was the basioccipital bone, but looking it up i see that the first vertebra is called the atlas, not basioccipital, which has me very confused? I looked a few places and haven’t found the connection between the 2(no pun intended:) Is the basioccipital bone PART of the atlas? I didn’t think there was anything between the skull and vertebrae. As far as the bone in question here, this IS the vertebra that connects directly to the skull, right??? ..whichever one It.
