  1. Hi everybody, Today I bring you pictures of what is allegedly a Pachy tail vertebrae with intact processes. I studied what has been found from Pachycephalosaurus and I'm struggling to place this bone along the tail, which is what the seller is claiming. I don't see where the processes are swept back like this one is. Could this be a different dinosaur? The same seller also has a Pachycephalosaurus rib which I'm also trying to figure out how to ID. Any help is appreciated.
  2. Found in an area overlooking the Little Missouri River basin, Clark County , Arkansas. I have found mosasaurus vertebrae, ball and socket in the general area where I found this one. My confusion is the intervertebral socket. Also, the overall shape is not round but flatter and with a figure 8 shape. Please comment and if possible, what is it.

    Articulated shark spine?

    Found them lined up like this in Pierre shale sd. Never seen verts like this before but heard shark vert are flat like this. Any insight would be great!

    Fossilized vertebrate

  6. Hi there. I found this on a field trip to a private quarry in Midlothian , TX (just south of Dallas). It was in limestone / shale in the ATCO formation, where there’s lots of shark teeth and fish bones. I’m pretty sure it’s been compressed as most of the shark spines I’ve seen are much more round and this is pretty oval shaped. Does anyone have any guesses as to species? Thanks in advance!

    Need help to identify this.

    Found in the badlands of Alberta. I put it in my hand to show you the size. If anyone has any idea it would be greatly appreciated. To me it looks like a tail vertebrae but not sure from what.

    Need help to ID heavy bone

    Utah - My 7 year old came home with this from a nearby field. It feels heavy like and hard like a rock. Some thoughts from medical professional family members is possible vertebrae or hoof from an animal. Any ideas for ID are appreciated. I'm not looking to sell, just trying to figure out what it is for my son. For now I'll let him think dino fossil until proven otherwise. Haha. I scanned it using photogrammetry and uploaded the 3D model to Nira for sharing images. https://myangelprints.nira.app/a/Mx7xVt3HQGmeJHJUiaeirA/1
  10. Hi everyone! I have my eye on an interesting set of associated verts from the Cloverly formation of Carbon County, Montana. I have zero experience with this formation and was hoping for a second opinion on whether or not they are dino and if they can be IDed. The seller is leaning towards Tenontosaurus. What do you all think? (I know that the last couple verts have some resto, the seller was open about that). Any insight is appreciated as always!

    Please could someone identify this. It was found on an ilfracombe beach, north devon.

    Vertebrae from the Peace River

    Found these sifting the Peace River yesterday glad to get out before the storm. First time posting vertebrae pictures let me know if certain angles are best. Thanks in advance

    Large Mammal Vertebrae

    Need help identifying these two vertebrae. The first I think is a mammoth or mastodon. I’m not sure about the second but it’s much to large to be bison or horse.
  14. Hello All, This was purchased on online auction site 20 years ago, but I lost the description and do not recall what dinosaur it is from. I am guessing maybe an achylosaur, hadrosaur, or triceratops, since I was collecting fossils from those creatures at the time. Don't know the location they were found or any other details. Your help will be appreciated! Thanks, Phil

    Identification vertebrea

    Hi, I was wondering if it is possible to identify what animal a vertebrae came from. I'm pretty confident it is a small back boan. It's just over a cm in diameter, and 4mm 'high' and was found at low tide on Monmouth beach in the UK. UK 5p for size reference.
  16. Cardita Bed, Bracklesham, West Sussex Vertebrae help please and thank you. Exposures of the richly fossiliferous Palaeogene sediments, which comprise the Bracklesham Group (Eocene). 46 million years old. Easy hunting here on the beach and sharks’ teeth may be found by the hundred. I have vertebra, shark and ray teeth and more needing some IDs .

    Unknown likely associated vertebrae

    Hello! Here I am again, with 3 unknown vertebrae… I can’t provide provenance, so I don’t expect to get the exact species. But can anyone tell me from what kind of animal they were? Are they dinosaur or something else? Thank you for your time :)
  18. Been looking through some of my old Hell Creek Formation fossils I collected near Glendive, Montana a few years ago and these are a few vertebrae I found but could never ID. I can provide any additional photos needed. Thanks!
  19. Thanks in advance. Any help you can give this newbie will be appreciated! I found this on east coast of central Florida, about a mile west of the Indian River Lagoon. It weighs about 10 grams. Most of the vertebra is hard like stone. Except on two of the sides, those cream color areas are like very densely packed powder. I've scraped away a lot of it and am wondering if I should try to clean it all out. Does an ultra sonic cleaner help with an item like this? Also, the concrete like deposits that are filling the openings. Can I aggressively clean those holes out? Any chance it's a xiphactinus?
  20. Found this today 7/21/23 around Westport, Washington, USA beach.

    Back in NJ - Found Something New

    Hello everyone! Long time no see, I moved back to NJ a few months ago and finally went fossil hunting for the first time again this week. I found this vert in Ramenessin, and at first glance thought it was a shark vert, albeit I did think about the odd shape but didn’t give it much thought before I went back to sifting. Once I got home and examined it closer, however, I realized it was something else. It has what appears to be two holes on the bottom, although one of them I’m debating if it’s really there and just filled with sediment or just something else, and one on the top. Instead of being round, the sides are flattened. Now, I remember the two holes on the bottom and the one on top as being described as distinguishing of plesiosaur vertebrae. However, it’s smaller than their reported size. I failed to find any good reference pictures of crocodile vertebrae to compare it to, but I was wondering if it would be croc instead. I don’t like to jump to plesiosaur when I haven’t really gotten my hand on NJ fossils in over a year. I’m pretty rusty on my fossils, and have the initial excitement of getting back into it possibly clouding my judgement. Let me know if you need any extra pics, I lost my magnifier in the move and I’m really feeling the loss right now, lol! Thanks!

    Opisthocoelous Vetrebrae ID

    Found in Brunswick County, NC. Egg shaped cross section. At first thought whale but noticed convex , concave ends which I thought was more included in amphibian. Thought on what this came from?
  23. I know this may be a stretch but this one just seems different from all the other concretions, etc. there. Measures 1-1/2” (3.81 cm). Sorry for the not so great photos, and thanks for any help.
