  1. Juvenile tyrannosaurid premax ID

    Hello all! I have acquired a very nice juvenile tyrannosaurid tooth from the Judith River Formation. I am fully aware that teeth from there are very difficult to be assigned a specie, but I was wondering if it could be narrowed down a little. Last time @Troodon was able to give me awesome info and help. The tooth is a premax tooth and is 1,7cm in length. I have a serration count for both distal and mesial sides: hard to tell for sure but it looks like 3/mm for the distal 4/mm for the mesial Thank you very much for all imput and info Kind regards, Thomas
  2. Mosasauroid Jaw

    Hi guys, I have recently acquired this Mosasauroid partial jaw. Seller claimed it is a juvenile Mosasaur. He acknowledged that some of the teeth may have been reattached. But he didnt know which, he got it from his supplier like this. And upon further questioning, he also admited that he is not absolutely sure about the genus. He speculated juvenile Mosasaur due to its size, but i dont think a smaller genus of Mosasaur, like Halisaurus, Tethysaurus or Platecarpus, is out of the picture. Please help me identify the genus of this Mosasuroid and the location of this jaw (dentary or mandible, left or right). If you would be so kind, please also point out to me, which teeth are wrongly attached, or maybe, composite. (The 3 red arrows are the teeth that felt quite real) Thanks. Edit: Almost forgot, seller claimed it came from a Phosphate deposit at Khourigba, Morocco.
  3. Juvenile tyrannosaur teeth

    Are juvenile tyrannosaur teeth rare?
  4. Strange juvenile gorgosaurus tooth

    On my birthday I got a juvenile gorgosaur tooth didn’t look special other then the colour but then I started to check it out and study it and instead of serrations there were small holes so I came up with a theory how juvenile tyrannosaurs didn’t have serrations until they got older yet I still need more proof to back up my theory but I found it interesting it was collected on a ranch in the Judith River formation not to far from the Canadian border it is 75 million years old here are some photos of it.
  5. Last summer, on the last day of a long weekend of backcountry fossil hunting around Lake Diefenbaker, Saskatchewan, my friend and I decided to stop our canoe at a beach where on a previous morning I had found a large baculites cuneatus specimen. This beach was an outcropping of a unit of the Bearpaw formation known as the Demaine sand, and dated roughly to the late Campanian. The locality was chock full of golfball to softball-sized nodules, each with a delicate, coalified fossil inside, ranging from crustacean parts, chips of driftwood, to loose vertebrae. It wasn't long before I was looking down at a split nodule containing the symmetrical lines I knew were a skull. So of course, I assembled it together as best as I could, wrapped it in a sock, and we loaded back into the boat to head home. Some typical terrain in the area. The formerly glacial South Saskatchewan River carves deep into the marine clays and sands of the Bearpaw formation: The nodule, rather unceremoniously wrapped in a wool sock: And unwrapped. Note the cervical vertebra just above the posterior end of the skull, and how part of the end of the snout is missing (sorry about the lack of scale bar, there's a photo further down the post with proper scale): I sent a photo to a paleontologist friend, and was quickly referred to the Royal Saskatchewan Museum, who of course were eager to accept the fossil (not to mention that I was technically legally obliged to hand it over, per the Saskatchewan Heritage Property Act... But it's what I wanted to do anyway!). About a month later, my friend and I met with two other paleontologists down at Lake Diefenbaker to deliver the fossil (this time more carefully wrapped in a shoebox...) and to show them the site where we had found it. One long and wet trip in the zodiac raft later, we were there. We assisted in the collection of more samples, this time coming up with an even broader variety of flora and fauna, including a small crinoid, some wood chips with amber, and some more decapods. One of the two paleontologists was excited to suggest that the locality probably represented a near-shore lagoon environment, and that the museum would likely be back to do some more work there at a later date. Unfortunately, we were unable to do so that summer because of the seasonally rising water levels of the lake, which flooded the site, but I've been told that my friend and I will be invited to assist with the operation again this following season. As for the fossil, it has since been delivered to McGill University to be CT scanned. Apparently, distinguishing the bone from the matrix has been long and tedious work, and not much news has reached us since the specimen was delivered some time last September. Here is an individual slice from the CT scan, from near the back of the braincase - notice how porous the bone material is, which is apparently another indicator that this skull belonged to a juvenile: I have been in close correspondence with the paleontologist from the Royal Sask. Museum who will be writing the paper to describe the find, but everything is more or less at a standstill until the work on the CT scan is finished. It's been a rather long wait, but I'm looking forward to its publication - I have been told that the museum intends to hold a press conference after the specimen has been described, and that my friend and I will be credited and involved in the reveal. So far, the museum has kept everything about the discovery deliberately vague, aside from a brief mention in a press conference, which informed an article that circulated around the Canadian media late last summer: https://nationalpost.com/news/canada/scientists-in-saskatchewan-discover-new-multimillion-year-old-fossils It's been an exciting and fulfilling experience overall, and I can't wait to get back into the field, this time with a more meticulous and careful attitude, knowing that there's scientific potential to be had from my future contributions. Anyway, here are some more photos from the lab at the RSM, with scale bar: Decapod claw: Crinoid crown: Thanks for your attention.
  6. This is a juvenile Psittacosaurus from Liaoning. Could you let me have your view on its authenticity and whether it is a composite? Thanks!
  7. This juvenile psittacosaurus is from Liaoning. Is it genuine?
  8. Priscacara indet. (Juvenile)

    From the album Green River Formation

    This is a very small 2.5 inch long Priscacara indet. These fish can easily be mistaken for a Knightia or an Amphiplaga because of the similarity in shape.
  9. Hi everyone, The tooth below is being advertised as a Pathological Juvenile CARCHARODONTOSAURUS Tooth on the popular auction site. Is this legit? I have my doubts... Please let me know your thoughts on this. I am curious to see what people think. Seller says Pathological teeth are not common and tend to be caused by infections during the animals lifetime and that the tooth itself has unusual depressions, narrow tip, twists and shape to it. Its 23mm and the seller says it is clear this Carcharodontosaurus was easily under 1 year old...
  10. Hello. Every once in a while I see these "juvenile Diplomystus" listed on our favorite auction site. The fins seem to match Diplomystus, but it would be great if someone with more GR knowledge than me could shed some light. The little guy is 1" long, tiny
  11. Mammuthus primigenius (Blumenbach 1799)

    From the album Vertebrates (other than fish)

    Molar from a juvenile animal. 15x10x4cm. Pleistocene. Found somewhere in Germany, but the seller couldn't tell me from where exactly.

  13. Is this juvenile horse?

    First time out this year. Peace River miocene to pliocene. Kind of a poor specimen, but intrigued me because it is so small. Is it juvenile horse? Friend said thought it might be 3 toed - but no isolated protocone. Please help identify. Thank you!

  15. I was wondering if you good folks here can shed some light on how do you tell the difference between fully grown sub adult and juvenile. Now I know obvious there is a size difference but how would you tell for sure with the example of teeth say for example you had two of different sizes as there where different size teeth in the mouth of spinosaurus and crocodiles and other theropods. Thank you for all your help Matt
  16. Is this a wolf skull?

    Hi everybody! I found this fossil online, and it the description says "wolf skull, of a young individual. Found near the remains of a mammoth" Can you tell if it is a wolf skull, and which species it is? What can you tell about the pictures?
  17. I am thinking of buying this but have no idea if it is just a small vert or juvenile as it's for the kem kem dealer I know it is genuine but there would be no way to put an i.d. on it apart from caudal.

  19. "Baby" Trilobite

    On a recent trip up to Little Falls, I somehow managed to spot this little guy while going through some scraps of shale. It isn't excellently preserved or anything and it's only an impression of a cephalon but what surprised me was the size of it. It's less than 4 millimeters wide and that's stretching it. It's certainly the smallest Triarthrus I've seen. Sorry for the poor quality, this is as good as I can get through a microscope.
  20. horsing around

    Hip While fig. 2 by itself would be worth the effort of opening this one(cute fish in hiding,and then some),this document also shows alcyonarian spicules,which ARE found in the fossil record. So it's not ONLY neontology.

  22. Wealden fossils from Brook Bay

    Hello everyone I am new to this forum but hear that you are excellent at helping with fossil id. These three fossils came from a recent trip to Brook bay on the Isle of Wight and I would really appreciate any input anyone can give me on them. The scale in the pictures is mm so both the tooth and rib are around 1cm long. The nearest match I can find for the tooth is a juvenile Baryonychid (based on Sweetman's paper). It is ridged down the edges rather than on the sides but it is not big enough to be Baryonix. There is one tiny rib(?) which I have no idea on and no idea whether there is anything on it that could support any identification? The last bone looks to me like it might be a limb bone from something about fox sized. Could that be right or am I miles off. I am really bad at ID so if anyone can set me straight on any errors above then it would be much appreciated.
