  1. Unknown Skull ID help

    Hello everyone, new member here! We recently started boxing up my childhood home to ready it for a sale and I discovered a long forgotten box that had a few fossils that my grandmother obtained during her ongoing 91 years on this earth. Almost all I believe were obtained by digs she went on around North America and chances are she obtained this one in the midwest. Most had tags like fish, mammoth tusk shard, and part of a deer jaw. I couldn't find an ID for this one, and upon asking my grandmother she hasn't the faintest idea because it's been decades and her mental state is slipping. If you need any more pictures of any sides let me know, my hand is only there to hold the two halves together, because unfortunately it hasn't survived in one whole piece. It measures about 160 mm. Another clue, but she did majority of her digs in Nebraska I believe. I'll have to Split up my posts with the pictures, I apologize.
  2. In case anyone's interested, there are two rather nice quadrate skull bones from a Spinosaurus for sale on our favourite auction site. These are definitely quadrate bones from a theropod. And I'm fairly sure they are from Spinosaurus aegyptiacus as well as the morphology is very consistent. Note that the bones are upside down in the photo. It seems it's both a left and right bone. Though I doubt these are associated.
  3. I finally completed the reorder of my collection of fossils and minerals. It is a wooden hexagonal display cabinet of several wood/glass shelf; in the pictures attached I only show some of them. I 3D printed more than 20 custom drawer compartments for the smallest specimens. I decided to go for a modular design, so I can adapt every compartment to the specimen. As printing material, I used a "wood PLA" filament 3D printed with 1 mm nozzle on the Alfawise U20 3D printer. I finally added a strip LED inside the cabinet door and powered it via a USB power-bank - so it is fully wireless. In this picture you can see some of my recent purchases: Two Sinosauridae indet. teeth from Kem Kem One Acheroraptor tooth from Hell Creek formation, Powder River Co., Montana Some Mosasaurus teeth from Kem Kem One Pterosaurs tooth from Kem Kem A piece of Rhinocerontidae indet. jaw from South Dakota Some ammonites, shark teeth, a Flexicalymene ouzregui, a couple of echinoids (I found the white one in a brick!); the Velociraptor skull is 3D printed as well. This is the other side. The big sand echinoid was also found by me in a brick! On the right there's a nice fossil coral: I never seen something similar, please let me know if you know it's name. Three fossil fishes and a nice ammonites cluster with some quartz in the background. At the end, some minerals... Now I only have to finish the cataloging of all specimen. I already finished with fossils, now I have to start with minerals - it will be very looong! What do you think? Do you like it? Ciao!
  4. Hello everybody So, these are some jaws / skull all from Mosasaur / Kem Kem that run on actions right now. It's out of my price range, but I post this here for educational purposes. I want to point out: The first Jaw is a composit. The seller admits it in the description. Real teeth, real jaw fragments, but put together. I have to be honest: I would be fooled by the first one. Can you point out why you see that the first Jaw is a composit? For me it looks like there are just some crack repairing. According to the seeler, the skull has been reinforced with a metal frame and camouflaged afterwards, some minor traces of preparation might still be visible. The rest is untouched acording to the seller. I can't provide more or better pictures. Thank you very much for your help! Jaw #1(composit) Jaw #2 Jaw #3 Skull
  5. I found this partial skull while hunting in the Peace River (Florida, Bone Valley formation). I am thinking it's either a raccoon or possum. Is there any way to tell? I am fairly certain it is not fossilized and it's pretty fragile.
  6. Went fossil hunting again in Florida's Bone Valley Formation. We returned to the Mammoth site where the large tusk section was recovered on the previous trip. After extensive searching in the area, no further Mammoth specimens were found. We still believe more of the beast is buried nearby, but this site is large and it's like looking for needles in a haystack. So, we are done with this site for a few months until the river drops further to allow better searching. We left the Mammoth site and continued downstream until we arrived at another one of our "honey holes" - a spot in the river that has previously produced numerous Pleistocene megafauna fossils. The site did not disappoint. We were likely the first hunters to arrive at it (it's too far downstream for casual lookers) and there was a lot of low-hanging fruit laying around. Josh proceeded to do some diving in the murky waters, and I waded around the knee-deep tea-colored water - doing a lot of the same bending and stooping that I do while shelling at the beach. The sun was directly overhead at this time, so it illuminated the coffee-black water and made it appear a tan tea color that was much more transparent. Things on the river bed could be easily seen. Lots of pebbles, logs, branches, clay lumps that resemble rocks, and fossils. All of these things are laying in a chaotic mess all over the riverbed in certain places. This lighting would not last, once the angle of the sun changes, the level of illumination drops and the tea colored water slowly changes to opaque coffee black. While the Sun was good, I found numerous bones including some vertebra and phalanges - the former is likely alligator and the latter is probably deer. Some of those appeared to be recent Holocene specimens and some were fossilized and were late Pliocene to late Pleistocene. Also found were numerous turtle scutes, some soft-shell turtle plastrons, some unidentified "chunkasaurus" bone fragments, a piece of Miocene coral with calcite replacement, and a strangely shaped bone of some kind. I left the best for last. Although not a fossil, I found an intact coyote skull that is in wonderful condition and has almost all of the teeth, including the canines. Also found was a partial small skull that is likely a raccoon or possum. These will clean up nicely and go into my growing collection of skulls. Footnote : strangely, we found NO shark teeth, which is very unusual for this site. Although, to be fair, we weren't really focused on shark teeth this time.
  7. The finest fossil owl

  8. Campanian microfossils

    Hi everyone! It would be amazing if any of you could help with identifying some marine microfossils I sieved. The origin is campanian (might be santonian) marine sediments. The location has yielded mosasaurs, fish, and sharks in abundance. But I have a few bone fragments that I have absolutely no clue what they are... Here are some of the mysteries:
  9. Tethysaurus?

    Hello! Just after some opinions on this. The teeth look a bit like they belong to Tethysaurus but I'm not 100 percent sure. I'm still getting to grips with mosasaurus etc! It seems to have an okay amount present within the rock. Jaws, sections of the skull, some vertebra. Does it look good or another potential composite? To me it looks pretty natural, however some composites are getting good these days! Thanks for the help, I'm still learning what to look out for!
  10. I'm interested in this skull, I have always wanted a Halisaurus specimen! Region -Morocco, Khoribga Size- 16.93 Inches This skull looks good to me, but is obviously missing parts, such as the rear of the lower jaw, some teeth, areas around the Eyes2. I'd like to get people's opinions if possible? The seller is very honest, and trustworthy in my opinion, The skull does look like its gone a few rounds in a ring, however this is my holy grail and something I've wanted since being a kid! which is what its all about right? However, I don't want the 5 year old within me to make silly judgments as it is listed for just over a grand. Is the skull a composite? Worth restoring myself? Genuine but rough? Worth obsessing over? I know it's one of those things were people will say "well it all depends on how much it is worth to you" however I don't want my naivety to cause me getting ripped off. Thanks for the help!
  11. Skull bone structure?

    I can't find any pictures of dino skull bone structure. Does anyone have any, or know where to find any cross sections, or pictures of skull fragments where you can see the internal structure? Preferably the forehead/top
  12. Old Bison Horns?

    I'm not sure, but I found what I think is the top of a bison skull with the horns. I found it in central Iowa, sitting on a sand bank in the middle of a river/creek. Could someone tell me if it is? The horns are kind of straighter like an ancient bison, could someone estimate the age and tell me if they think it is? The horn spread is just over 21 inches. It seems pretty old and almost fossilized. Thanks for any help in figuring it out. I'm really interested in what you have to say.
  13. So this has cropped up on an auction site. My friend is tempted by it, however I believe it to just be a rock. It is claimed to be a Psittacosaur Skull. The seller claims that they acquired it off a 'geologist' however to me, it looks like an eroded rock, and lacks any characteristics of being a skull? I feel like it could potentially mislead uninformed newbies? Pictures aren't fantastic. I could be totally wrong of course, however can anyone else see if it is a skull or not?
  14. Heavy Calcified (?) Skull

    Another "rock" from my desert house. This one was covered in sediment, which I mostly chipped off. I think there may still be some skin on there as there is also some reptilian texture but much of it came off attached to the top layer of sediment (which I saved). Its solid mineral of some sort & very heavy for its size. It seems smashed in along the jaw on one side making it a little lopsided from all angles & I believe there was a longer mouth which is now thrown over the other side and wrapped the other side around a little. You can also clearly see some kind of vertebrae through the mineral running along the center of the bottom of the head/jaw as well as the top row of teeth along each side of the jaw. From the front you can see where some teeth got knocked inward. I can post more pics, angles, or details if you'd like but here's a start. This is the front/side. You can see the teeth knocked inward. This is underneath. You can see through the mineral and see the outline of a vertebrae down the center as well as where it attached near the back. Look closely and you can also see the top row of teeth as well as where they start where the jaw meets. This is the back of the head/skull This is the other side view. I believe that lump towards the front of the face is a mouth that got broken & wrapped around the side. This is head-on. You kind of have to tilt your head to the right to see it at the correct angle since it's been smashed to the side. I believe that dark spot towards the center was the opening for the nose and the thing twisting up and to the left along the bottom portion is the longer mouth that got broken & wrapped around. Or else . . . ? There are a lot of "rocks" like this in my yard but this one has the most detail so far. I also took photos of the bones & shell this week & will get them uploaded this weekend.
  15. Kem Kem skull element/thing

    I recently purchased this item. It was described as a piece of dinosaur skull. I never trust these IDs of course, but on the other hand, I didn't know what it was. Crucially, it was affordable, so I bought it anyway. It has arrived today and is quite impressive, in its way. The question is; what is it? This is the main boney face of it. The other side is pure matrix with no shape or distinguishing features, so I didn't photograph it. Note the bone protruding from the bottom. This thing needs a LOT of prep. The bone has a strange honeycomb structure, full of large empty pits. This next bit (also seen at the bottom of the picture above) interests me, because it appears to be identical to the substance I asked for help with here: It is literally right up against the bone, on the left. MYSTERIOUS! If anybody has any ideas what this object might be, I'd love to hear them. So far I've narrowed it down to: Crocodile (that's what I associate any honeycomb style stuff with, rightly or wrongly) Dinosaur Elemental kaiju summoned to save the earth during time of strife Extremely big fish Thank you!
  16. Broken woolly Rhino skull, Need Help!!!

    Hi guys, Recently I ordered a partial wooly rhino skull and as you could imagine I was on the brink of tears when it arrived. I ordered from overseas and someone must have dropped the box or something? but I am contacting the seller to see if I could get a partial refund (but I have my doubts). So I am trying to be positive and make this my "not so little" prep project, there is one problem though. I have no idea what I'm doing! (I don't even know if It's salvageable) So this is where you amazing people come in. I would love to get this looking as original as possible and was wondering if there was a product for that, or if I could just use household items, Or maybe there's some other solution that is foreign to me? Anyway, I would love to here every idea and any advice you've got. I have taken some pictures that are listed below, the last two are it in the condition before it was sent. If you need any more pictures to refer to, Please! contact me otherwise thanks for taking the time to read this and hope to hear from you soon. Thanks so much, Ryan.
  17. Mosasaur premaxillary bones

    From the album Marine reptiles and mammals

    2 unidentified mosasaur species' anterior end of premaxillary bones. One with teeth broken off just beyond the skull, and the other has 2 remaining teeth, with the rest broken off at the level of the skull. the larger fossil was found in the phosphate mines of Khouribga, Morocco. ive since lost the information for the smaller fossil, sadly.
  18. Triceratops skull and brain case

    From the album Dinosaurs & flying reptiles

    Another view showing an area of what I do not know. I'm guessing it involves nerve fibers/channels.
  19. Triceratops skull and brain case

    From the album Dinosaurs & flying reptiles

    Another view showing more channels/cross sections of blood flow(the small solid dark gray areas), and nerve channels. I'm not entirely sure what the large dark areas are, although I believe it to be related to blood flow as well.
  20. Triceratops skull with brain case

    From the album Dinosaurs & flying reptiles

    Another view showing the spongy internal bone growth
  21. Triceratops skull and brain case

    From the album Dinosaurs & flying reptiles

    2 pieces of a triceratops skull with brain case impression. Blood vessels, veins, and arteries visible, as well as nerve channels. I have to contact in order to get the fossil information again.
  22. I'm 3D printing this Velociraptor's skull - https://www.thingiverse.com/thing:2736627 Details are very realistic, but I didn't found any real Raptor's skull image to compare. Internet is full of replicas... Anyway, if you're going to 3D print it, consider that it is a very pain. It is badly split, and it is not very easy to 3D print: more than half of the pegs will break and some of the pieces have mesh issues. Also, I suggest to print teeth flat on the 3D printing bed, and not as the original STL. I will update the post with new images as I glue and paint it. Regards, Adriano
  23. Bridger fm. Amphibian

    Hello fossil friends. I have this skull piece here that's quite interesting. Looks to be some kind of amphibian skull. The locality is Bridger fm, but after doing some research I haven't been able to find any information on amphibians from this locality. Would anyone be able to shed some light on an ID for this piece?
  24. fossils in a museum in Palm Beach

    when i was in miami during the summer i went to this mall in palm beach where they had this museum that has dinosaurs and other prehistoric animals but they are some fossils in there that i dont know what they are so i wanted them to have IDed.
  25. Kansas pliosaur skull

    Just got a new paper from ResearchGate It basically describes the dentition morphology of Megacephalosaurus eulerti, a pliosaur from the Turonian Carlile Shale of Kansas. The paper also looks at general aspects of M. eulerti cranial anatomy. The study is based on a beautiful skull housed at the Fort Hays Museum of Natural History (see below). Madzia, D., Sachs, S., & Lindgren, J. (2018). Morphological and phylogenetic aspects of the dentition of Megacephalosaurus eulerti, a pliosaurid from the Turonian of Kansas, USA, with remarks on the cranial anatomy of the taxon. Geological Magazine, 1-16. Abstract of the paper: Megacephalosaurus eulerti is a large macropredatory plesiosaur representing one of the last members of the diverse pliosaurid clade Brachaucheninae. The taxon was established upon a nearly complete skull including the mandible and fragments of the postcranial skeleton originating from the lower middle Turonian (Upper Cretaceous) of Kansas, USA. Owing to its age, reasonable completeness and its state of preservation, M. eulerti bears important anatomical details regarding the last brachauchenines. Here we assess the dentition of the taxon, compare the teeth to those of other thalassophonean pliosaurids and comment on the utility of these results for inferences of the phylogenetic relationships of the last brachauchenines. Additionally, we provide remarks on the cranial anatomy of M. eulerti, revise character scores of this taxon used in current phylogenetic studies and address the phylogenetic relationships within Brachaucheninae. Parsimony analyses, aimed to test different char- acter sampling and tree-search strategy, inferred only a single unambiguous synapomorphy uniting a clade formed by mid- to Late Cretaceous brachauchenines: presence of subcircular rather than subtrihedral/trihedral cross-sectional shape of the teeth. Still, the last brachauchenines (Brachauchenius and Megacephalosaurus) can be roughly characterized by a switch from anisodont to subisodont dentition and reduction of their tooth count. Nevertheless, the overall knowledge of the origin, phylogenetic relationships and distinguishability of brachauchenine pliosaurids remains poor and represents a subject for further extensive studies and modifications in taxon and character sampling. For those who want it, I can send it by email to them
