  1. Hi, just wanted to double check if the ID of this mosasaur jaws is correct and if there is any composite stuff (at least from may point of view I can't see any). This first in theory it's a Eremiasaurus heterodontus from Oued Zem. The second one it's a Prognathodon curii also from the same place. Tagging @Praefectus and @pachy-pleuro-whatnot-odon. Thanks guys!!
  2. Hi, Was just wondering if this is really a Spinosaur jaw fragment because most I see labelled as that turn out to be Croc instead. It is a small fragment at 6.5cm in length and comes from the Kem Kem. Thanks!

    Mosasaur Jaw

    Hello, I bought a Mosasaur Jaw fragment from Morocco at a local expo, at first sight I thought that maybe it's prognathodon sp. but I would like to know your opinion. The jaw has 3 teeth that I could check that belong 100% to the jaw and the other at least seemed to have the same morphology but it's not possible to know if the belogned to the jaw or not. Any way, knowing this I thought the price was fair so I bought it. I have marked with red the teeth that for sure belong to the jaw so it can help with the ID. If it helps with the ID, the teeth have 2 edges, one on each side. On t
  4. The genus Centrophorus sp. represents a very interesting group of sharks within the Centrophoridae (Squaliformes), which can be found up to about 3000m below the sea surface. The largest representatives of this group reach a body length of 170cm. Not only because the sharks of this group are among my favorite sharks, but also because fossil finds of this species are extremely rare, I decided to write about this topic and compare fossil and recent Centrophorus species with each other, as well as collect the known information about them. The modern genus Centrophorus has been repeatedl

    Found this in the Hell creek formation in eastern montana. It measures 2 7/8” long by 3/4” wide. It definitely is not crock. Leaning towards paraxenisaurus. “Strange lizard”. It would be rare in the Hell Creek.

    Archaeotherium Jaw

    Working on an Archaeotherium jaw. It is in pretty rough shape and wish the teeth were in better condition, still a neat specimen. It still needs work but what do you guys think so far??

    Can anyone identify this jaw?

    I found this lower right jaw bone exposed on the bed of a creek in north central florida. It appears to be from an extinct canine species, but I am unsure and figured someone on here probably has more knowledge than I do on what it could be. Measurements are 7 cm in height at the tallest point, almost 15 cm in length, and 1 cm in thickness. There is one molar missing, and the incisors at the front are missing as well. Any help is greatly appreciated.
  10. After no rain for many months we got a big 13 foot rise last weekend. I was hoping that would wash away all the mud and uncover many great fossils. Unfortunately it was still few and far between. The mud has been halfway washed away, which is halfway to where we want it, but the fossils are still not uncovered. Here are a few of the things i found: A couple decent but small mosasaur verts. Also the in situ shots. Decent fish jaw. Not sure which species though. A cool shell from the grey shale zone. All I eve

    Dunkleosteus armor/possible jaws

    From the album: Sharks and fish

    Front side of armor which I believe could be the edge of the jaws! It comes to what would have been the razor sharp shearing edge, greatly worn down now, though. I also believe it could be the jaw because of the clear vertical wear lines on the surface, from being sheared against the inner surface of the other jaw, which is how they kept the edges razor sharp like scissors. I have seen similar wear lines on placoderm shearing jaws, so what I believe to be reasonable observations point to the possibility(maybe even likely?)of being from the cutting edge of the jaws.
  12. Hi, so i just got this mosasaurus jaw from morocco, could someone help me to figure out if it is real? If so, is it possible to say from which exact species it is? Its said to be from morocco... Thank you in advance!

    Kem Kem jaw fragment

    Hi all! What do you make of this 8 cm long jaw fragment from the Kem Kem beds?
  15. Find this laying on top of Pierre shale out cropping as if it was dropped by bird or came out of above matrix. I tried putting a tip of it into vinegar and did not fizle but it did degrade the bone and made it soft so it would kind of fall into powder pieces when scraped. I tried burning the tip of it but it did not burn might have been because it was wet from the vinegar. What could it be? Thanks!
  16. Hello, I have what was traded to me as an ornithischian jaw from the Morrison Formation of Wyoming. It measures 5 cm high and has 2 teeth sockets. I believe it may be a Camptosaurus (due to being the only large ornithischian there) partial jaw, but I cannot exclude the possibility of it being a partial theropod jaw. May I have your thoughts? Thank you.
  17. Hello, this is a "mosasaur jaw" from Morocco, I bought it knowing that the jaw was super suspicious and just considered it as a display for the teeth. But on further examination, as you can see on the close up photo, the texture of the jaw bone seems too good for a cast (at least in my opinion and comparing it to other moroccan jaws I saw). Can it be a reconstructed real jaw? It's a crocodile jaw or similar? Or a really good cast? What do you think?

    Fossilized Lower Jaw from Nebraska

    Hi, Recently I received several unprepared fossils from Nebraska, although the exact location is unknown. One of these fossils I have been preparing is a lower jaws from an unknown animal and I would like to know what it is, and if possible an idea of the time period and/or formation. Any help would be appreciated. I currently think that is probably a lower right jaw from the oreodont Merycoidodont. The dimensions of the jaw are 6cm by 14cm, and I am happy to post more photos if necessary. Thanks!

    Hadrosaur or Ceratopsian Jaw?

    I found this in the Judith River Formation years ago but have never got it fully identified as a Hadrosaur or Ceratopsian jaw piece. Any help will be appreciated.
  23. Hi, I'm not sure what exactly this is? it is a strange fossil and according to the seller it is a Plesiosaur skull with a few traces of bone? and was found above the ground. Not sure what to make of that but I think I can see some tooth sockets and maybe the eye sockets (unless I am very mistaken), it just has me stumped! thanks for any help

    Basilosaurus jaw?

    Is it just me, or does this look like there’s a good chance that it’s either totally separate pieces with significant restoration connecting it, or even just quite a bit of fake areas? I feel like especially from the right side, it appears to be a huge amount of just matrix visible, and even on the left side a good deal of area that’s just matrix. I know that matrix isn’t unusual on pieces, and I wouldn’t mind small amounts of restoration/places of matrix filing in missing areas, but not large portions of something.
  25. I always have trouble telling if jaws are real or manufactured. As far as I can tell this looks real (but incomplete). Let me know if I'm missing something. Looks like there's some bonus verts in the matrix as well.
