  1. In my collection (about 30 fossils in total, but it's always expanding!) there is only one fossil of terrestrial reptile (but I'm saving some money to get another one soon!) ------------------------------------------------------------------------------- Species: Mycterosaurus longiceps Size: 1 cm x 5 mm Age: 280-275 mya (Lower Permian, Kungurian) Origin: USA, Oklahoma --> Dolese Brothers Quarry --> Richard's Spur About this fossil: one of the smallest ones in my collection, it is a partially complete caudal vertebra of Mycterosaurus longiceps. It is missing only a small piece in the upper part of the vertebra.

    Baryonyx vertebra from UK?

    Hey guys, Recently received this vertebra from Brightstone bay, Isle of Wight, UK. Could it be baryonyx? What else could it be if it’s not? Size is 7,5cm long. Thanks for the help.

    What kind of dinosaur is this?

    What kind of dinosaur is this? Vertebrae from North Africa Probably the Cretaceous period But I don't know anything else Thank you for your answer
  4. Not sure if this goes here or in Fossil ID but I’ll post here… This is one of my latest online purchases, and one I had to snag because if this is what it’s supposed to be it’s a neat piece. But seeing as I can’t personally verify it myself, I thought I’d post here. This vertebra was being sold as Trinacromerum sp. While I doubt that just a centrum like this is identifiable down to genus, I would like to know whether or not this really is a Polycotilid vertebra. I think it’s likely because it’s a very sizable bone that’s not mosasaur, but just want to check. This fossil is, according to the seller, from the Niobrara Chalk of Kansas. And as can be seen, this fossils as pretty obviously been flattened by geology. Thanks!

    Hell Creek Crocodylomorph Vertebra

    Anyone familiar enough with the Crocodylomorphs from the Hell Creek Formation to be able to help in determining a probable genus or species? I purchased this specimen and have been unable to find images or research papers with similar examples.

    Kem Kem Vertebra

    Hi everyone . I recently receive this vertebra from Kem Kem basin . I am not sure about ID of this vert ... could be Theropod vert? I removed some of the matrix that covered this vert. I hope it helps a bit in ID There are some gap fill/restored areas to this vert as clearly see in photo. Thank you in advance and Happy Christmas ! Guns

    Spino caudal vertebra?

    Hi guys! I found this vertebra on sale, probably caudal, can be spino? There are only these pictures… Thanks!
  8. Here’s a vertebra fragment I found in Cretaceous Black Creek group sediments of North Carolina. It’s not turtle, and it doesn’t look like any crocodile vertebra I’ve ever seen. That would leave mosasaur, plesiosaur, or dinosaur. Personally I think it’s mosasaur, but I could be wrong and it may not even possible to ID further. Any thoughts?
  9. Hi all, I recently decided to buy the below plesiosaur vertebra after having seen it for a long, long time. It dates to the Callovian of the Oxford Clay and was found at Peterborough. I suspect it may be attributed to Muraenosaurus leedsi, as it comes from a cryptoclidid plesiosaur, but is both larger and more elongate that the typical Oxford Clay Cryptoclidus vertebrae I'm familiar with. Supposedly coming from an old collection, it has a blackened exterior that doesn't cover the entire piece, with the more common buff colour visible underneath. As such, I expected the dark colouring to be simple dirt or may be some kind of consolidate that could be removed using acetone to leave a nice and clean looking vertebra in its place. However, since having tried acetone cleaning, the dark colour doesn't come off - suggesting that it isn't surface dirt and any consolidate, if present, is not soluble in acetone. I've also noticed that the black colour doesn't spread equally across the vertebra, which is most noticeable towards the top on the front face (first image) where one half of the vertebra is buff, the other black, with a hard separation in between. As this mottled pattern can be seen in other places on the vertebra as well, I thought that, may be, the vertebra might have been in a fire and have become covered in soot. I find additional support in the latter hypothesis in very brittle pieces of bone in one or two spots, with a charcoal-like grainy texture. Lastly, then, I've spotted a tiny edge of yellow staining/infill in an area where the vascular structure of the bone is exposed, with some white infill in an area adjacent - which I've now started worrying might be pyrite. My questions to you are: Origin of the blackening: Does the black clouding of the vertebra look like natural preservation? Related to the above: could the black clouding be due to pyrite decay? In contrast: could exposure to fire cause the clouding pattern seen on the vertebra? What consolidate might have been used to result in such colour patterning? Cleaning: Is there a way to remove soot from a fossil? Has anyone tried? Other than removal by acetone, what other ways might I try to remove an old, darkened consolidate? In case of decayed pyrite, I don't think there's anyway to clean the surface, other than, may be, through careful sandblasting, is there?
  10. Hi guys, I was considering purchasing the attached vertebra as a Christmas gift, however, I'm aware that identifying partial material down to the genus level can be tricky. I would really appreciate any opinions as to the identity of this vert, it's labelled as Baryonyx sp. indent and measures 8.9x10x10 cm collected from the Wessex Formation, Isle of Wight, England. From my own reading around on the forum and online (see attached figure from https://www.researchgate.net/publication/285762094_A_new_specimen_of_the_theropod_dinosaur_Baryonyx_from_the_early_Cretaceous_of_Portugal_and_taxonomic_validity_of_Suchosaurus) I thought that this could be the ventral portion of a caudal vertebrae, but I'm definitely no expert so please correct me if I'm wrong!
  11. A few things from Post Oak creek, Eagle Ford. I don't have a shark tooth like this so easier to ask for ID on first one The tiny little vert I'm assuming is fish, not expecting more specific , this is the smallest one I've seen. Last item I have no idea, maybe fish related?

    Vertebra from Aquia Formation

    I’m guessing sea turtle, since it doesn’t appear to be snake or croc?

    Sauropod vertebra?

    Good morning, I Saw this vertebra for sale and advertised as a Sauropod cetiosaur, since I'm not an expert I would like to ask if you guys think it's a true sauropod vertebra or It can be instead of a pliosaur, or plesiosaur since they are more common. Thanks In advance

    Post Oak Vertebra

    I recently collected about 300 pounds of matrix from the Post Oak creek in Sherman Texas, and I’ve since been searching through it when I get the opportunity to. I’ve found quite a few vertebrae, all from fish, but I found one last night that has me scratching my head. It has some matrix that has solidified and will need to be removed, but I thought I could post it beforehand in case anyone had any thoughts regarding the identification!

    North Carolina plesiosaur or shark vertebra?

    I just recently found this bone in the Cretaceous Black Creek group deposits of eastern North Carolina. I originally thought it was an oddly shaped shark vertebra, but now I think it might be a worn plesiosaur vert. based on the images I looked up online. The overall cross sectional shape is elliptical, and the center looks much too thick for shark (doesn’t pinch in towards the center). Any thoughts? Thanks!

    What does this vertebra come from?

    From Stratford hall Virginia a decade ago. How do I know if it’s mammal or fish or something else?

    Micro-vert or crinoid ossicle: Jurassic finds

    I keep finding these peculiar ovaloid shaped fossils in the Cotswolds, Inferior Oolite Group, UK. It doesn't particularly matter which formation they are from, as I've found them in every single one so far! Here's one of them. They always have a side with a convex bump on it (pictured above), and a side with a concave dip, suggesting tessellation. And here's some microscope images:
  19. Please help identify this fossil. Some type of vertebra I believe. Thank you for your time! Tom

    Need help with identification

    Found near Lake Huron Ontario. I can see the symmetry and the darker pieces on top and that they coincide with the curved spacing below. Hard to see in pics but I’ll do my best to show. I pointed out the two less obvious in the possibility it help in identifying due to the structure etc. The other is the lighter grey square that is more obvious and visible. Thank you
  21. Hi! I found this bone on a remote, virgin beach in northern Iceland just the other day. I’m completely green when it gets to those topics and have thus no idea what it can have come from. Possibly a piece of a large fish or seal vertebra? Any ideas? Can anybody help me identify the bone?
  22. Hi guys! I went to look for some bones on the beach like I always do when the river flow goes down, there's always something but the problem is that I never know what I found. The last time they helped me here to identify a whale humerus, thanks a lot! This time I found several bones, but I had to discard many because they were badly broken or did not look interesting. All of these are about the same (12-18cm) The one that looks better is that kind of vertebra, I searched with Google and it says it could be from a bison, but sounds weird a bison in a beach, and btw, the place where I found them is Uruguay, South America - where there never were bison I think. And sorry for the bad pics, but it was the last hours of sun, I can take others if required. Thanks!!
  23. Permian amphibian jaw found by me this year. Place:Russia, Perm Territory, location "Perskiye Kluchiki". Age: middle perminan upper kazan or ufa layer I have a description of the location (careful, Russian!) https://sciencejournals.ru/cgi/getPDF.pl?jid=palrus&year=2020&vol=2020&iss=3&file=PalRus2003015Sinichenkova.pdf I would be very grateful for any help in determining

    Fish vert and fish tooth

    Finds from a week ago. I am used to finding Sawfish verts more often than Shark verts. This may be a Shark vert. If so, type of shark? Interesting and isolated damage. Here is a view after drying: Size Diameter 34 x 17 mm max/min, and 28 mm height A 2nd find: I immediately thought Drumfish, because I know of not other fish that has similar teeth ? Is it?
  25. Hi, I recently found a bone that looks like either a vertebra or a phalanges. The bone is from eastern North Carolina, legally collected from public land, and comes out of either the Cretaceous Tar Heel or Bladen formations. Both marine and freshwater organisms as well as dinosaurs are known to be found from the general area. The bone does not look like it comes from a turtle or crocodile, but I could be wrong. Is it a dinosaur or mosasaur bone, or something else? And no, there is no way this bone is Cenozoic. Thanks!
