    Possible Dinosaur Vertebra from Morocco?

    Hello! This is my first post so be gentle I have a vertebrae from Morocco here that i cant seem to figure out. The owner of the collection I'm examining recalls purchasing it from Morocco, but doesn't recall if it comes from the Kem Kem beds or from the High Atlas Mountains. After some dusting and light acetone cleaning was able to determine that it is in fact a vertebra, but I'm not sure of the species, as the piece is slightly deformed and lacks processes. My best guess so far is a sauropod caudal vertebra, possibly Rebbachisaurus, but I'm having difficulty in finding any reputable sources that would confirm this. I could also understand if it came from a large theropod, but has lost its shape due to deformation. Sadly, most of my expertise is with Hell Creek fossils, so I'd really appreciate any help that can be offered Lastly, if the piece is of any significance (undescribed or poorly described species) it will most likely be donated to the local museum! So that would be cool. Thanks again!
  2. 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!
  3. This vertebra is being sold as a Spinosaurus cervical vertebra, according to the seller it has a few restorations including a transverse process. Comparing it to other Spinosaurus cervical vertebrae I notice the holes on the sides of the centrum are missing as well as the downward pointing transverse processes for the cervical ribs. Instead it has lateral pointing transverse processes which doesn't fit the morphology of a cervical vertebra. Could this be a dorsal vertebra instead or a composite of a cervical and dorsal vertebra? Also, are there any more restorations on it that are incorrect? @jpc@LordTrilobite Location: Ifezouane Fm, Taouz, South Morocco Size: 27cm x 19cm (10.6" x 7.5")

    Fossil vertebra

    Hello everyone, I'm new to the forum. I found a fossil vertebra on Trimmingham beach this morning...( North Norfolk UK). ..and wonder if any members could tell me what mammal this could possibly be from by the attached photos. Thanks
  5. Hello, I found this on the Brazos River Bend near Sugar Land, Texas, US. Not sure if this is a tooth, a vertebrae or just a stone (see pictures). Any help will be greatly appreciated, Thanks Saji John

    Vertebra puzzle

    Hi folks, I haven’t posted in a while, but I still visit and enjoy the forum most weeks. Thanks everyone. Just a curiosity. A find at the end of the day that, made me think….that’s a little odd, is that normal? I don’t know enough. but I know where to ask! Here is half of a vertebra. 2 inches across. At this site it can be anywhere from Cretaceous to Pleistocene marine. New Zealand. we’ve found Miocene and Pliocene cetaceans, seals and penguins. Plus cretaceous plesiosaur and Mosasaur vertebra. There is huge variation in the preservation of bone from these ages. This vert fragment doesn’t seem to fit into what I’ve seen from cetaceans or marine reptiles. But that’s just the bones I’ve seen. It has thick dense cortical bone and much more open cancellous bone than I’m used to for cetacean. But wondered since it’s small if it could be an ontogenetic thing. Thicker cortical bone in juveniles. Anyway just a curiosity and an opportunity me to learn something. Thanks

    Tyrannosaur vertebra?

    Hello May I know if this is the vertebrae of the tyrannosaur? And is this the tailbone? It comes from the Jordan, Garfield County, Montana size: 3.35 x 3.2 x 1.5" Thanks IMG_6739.HEIC IMG_6737.HEIC IMG_6738.HEIC

    Palaeophis typhaeus vertebra?

    I recently spotted a Palaeophis vertebra for sale, labelled as having come from a Palaeophis typhaeus. The vertebra was found in the Ouled Abdoun basin in Morocco and is Ypresian in age. I have only every seen Palaeophis maghrebianus vertebrae for sale, so I was wondering if this was a mistaken ID. Thanks in advance for confirmation Othniel
  9. I’m going through my collection of unknowns, and came across this little guy. It is a small, ornate vertebra collected from the Pliocene Yorktown Formation at the Lee Creek Mine in North Carolina,, USA. Scale in the photos for size. Bird? Snake? Other? thanks

    Big vertebra dinosaur?

    All, can anyone give me a positive id on this possible vertebra I found in creek bed wall? little of rock was sticking out of bank. I was digging in a layer where i find selenite crystals with coal in the gray brittle dirt. think someone commented on the only other vertebrae I found is called gray Merle or woodbine formation. it is very brittle and did one coat of leather shellac to keep from crumbling any more found north Texas any ideas would be much appreciated
  12. Hello everyone! I recently visited France twice to hunt for fossils. I wanted to visit Villers-sur-mer at least once before the interdiction to collect and I was rewarded with an amazing vertebra: Guess it's marine crocodile, since the shape doesn't fit with ichthyosaurs, plesiosaurs or dinosaurs. Here it is cleaned up sitting in it's little box: I also found this mystery really eroded bone. It's quite big and chunky: Would anyone have an idea on what it's from/which bone it is? Then the mystery from Wimereux. At first I thought it was petrified wood, but it's dry now and it doesn't crumble. It's hard, heavy and there's some pyrite going through it: Would anyone have an idea? Thank you!

    Vertebra

    Hello everyone. I'm not sure if this vertebra comes from the Tyrannosauridae family? It comes from Zhucheng City, Shandong Province, China. the size of the vertebra is 22cm. Thank you for all the answers.
  14. Thanks in advance for your help! Post Oak Creek, Sherman, Texas. Turtle scute or part of vertebra?

    Fossil Vertebra from Florida

    This was found inland in Sarasota county. It's clearly a vertebra. Most people seem to say that it's from a whale? Can't it be any large fish or animal? Any insight would be appreciated.

    Great white shark vertebra?

    Hello! I recently found this lamnoid shark vertebra in Tampa Bay along the shore. I think it's from a great white shark and assume it's fossilized, but I'm not sure. What do you think?
  17. Hi all - found this in Central Texas. It was a surface find in an area mapped as Ozan formation. Thought it was an old railroad spike at first. Is there enough left of it to give a general ID? Kind of looks like some mosasaur vert pics I’ve seen. Any ideas appreciated. Thanks!

    SE Texas - What's this from?

    I found this vertebra... and another one similar in shape. It has a bunch of wear and is broken all over. It is fully mineralized. I've been trying to compare it to other mammals and can't find a match. I know there are SOOO MANY possibilities but maybe someone might know what it is from or can send me in a certain direction. Size is: 3.25 inches at the widest. Sorry...was still cleaning the algae off of it.
  19. Hi all, This is a follow-on from the first post in my ‘Adventures in Thin Sectioning’ thread where I showed this fossil from the Aust bone bed. I wanted to have it scanned so that I have a record of both halves before I try to make histological sections of the ‘offcut’. Luckily, my department has a micro X-ray CT scanner (Nikon XT H 225ST) and when there was a gap in demand I was able to book time for a couple hours of scanning. I got three separate scans done, the two pieces of the Aust block done together and then two articulating fragments from the Woodhill Bay Fish Bed at Portishead which are full of upper Devonian placoderm and sarcopterygian fragments. Florists foam is used to hold the pieces in place during scanning as it is easy to press the rocks into and low enough density as to not interfere with the scan. The scan for the Aust block took a little over an hour, and after reconstruction the vertebra is differentiable. The scan isn’t brilliant due to the abundance of pyrite in the stone which scatters the X-rays but it should hopefully be good enough to segment out the bone by hand and make a 3D model, so mission accomplished! The scans for the Portishead material were much shorter exploratory scans (>30 minutes) but turned out better due to the lower density sandstone matrix and lack of pyrite. Both pieces are full of fragments of scale and bits of bone but the larger of the two has a couple particularly interesting features. A large ?spine which I haven’t yet identified: A fragment of jaw with three teeth, likely belonging to the Sarcopterygian Holoptychius: Using a free program called Drishti I’ve been able to quickly reconstruct the Portishead scans in 3D and while the differentiation between bone and matrix isn’t fantastic it is good enough to get an idea of the spatial arrangement of the fragments. I intend to spend some time learning to segment out the fragments individually in Dragonfly (another free program for working with slice data) but am currently struggling with a few bugs so that will have to come later. The two fragments as rendered volumes in rough alignment: A rough rendering of the locations of the bone/scale fragments in both blocks. I believe the majority of the scales are Holoptychius as it is the most abundant taxa in this deposit: Close up on the area with the fragment of jaw, the three teeth are clearly visible as well as the stumps of two others: Thanks for looking, let me know if you have any questions.
