  1. Hello everyone and hope you're all having a wonderful day. Recently, I had the brilliant opportunity to volunteer at the Australian Museum in Sydney. It has definitely been a highlight of this year for me, and I thoroughly enjoyed it! While I was there, I spent a lot of time exploring the museum, and eventually saw and took photographs of every palaeontological item on display I am aware of, and would like to show them all to you now as an early Christmas present. I do know @Notidanodon did get to share some photographs of the museum a while ago. If you're wondering why the opalised shells Notidanodon shared are not in this topic, they are no longer on display as far as I know. I did also get to see some fossil specimens behind-the-scenes, but I did not get to take pictures of them, so these are only the fossils and replicas on public display I do have a lot of photos of other things as well, particularly the Rameses travelling exhibition, as well as labels of the palaeontology items, so if you want anything in particular, please PM me. I also have a lot of similar photographs of the Australian Fossil and Mineral Museum in Bathurst, and will probably post those next year. This will be a long topic, and I doubt I'll finish it all today, but here goes: Dinosaur Gallery Entrance Replica skeleton of Jobaria tiguidensis and Afrovenator abakensis, originally discovered by Paul Sereno. You'll see that a lot of Sereno's skeletons are on display in this gallery, as he was involved with its creation. The Jobaria mount from behind; note the upper floor of displays no longer accesible which the sauropod's head reaches up into. From talking with the other volunteers I'm pretty sure this upper floor used to be part of the 'More than Dinosaurs' gallery which the current Dinosaurs gallery replaced, but I cannot find any images of the older gallery to confirm this besides a close-up of a Stegosaurus (which is still in the museum). Mesozoic Plants Pretty nicely, there is a decent amount of space in the gallery dedicated to non-dinosaurs. While I would have preferred a simple 'Fossil Gallery' with a variety of extinct organisms on display, this is still a good compromise. Photograph showing how the plants section, labelled 'A Changing World', is presented. Each of the large windows is into a cabinet displaying the real fossil plants, and are accompanied by a reconstruction of terrestrial life at the time at a child's eyeline, so they can get a better idea of how life on land looked in each period. You can look into them through the small rectangles below the large windows. They all appear in '3D'. The orange circles cover up areas where children can smell what certain plants would have been like (the Triassic one is of a conifer, and the Cretaceous one is of a flowering plant). Australian Triassic plants. Top left is Rissikia media, bottom left is Dicroidium zuberi and right is Cladophelbis australis. Here is the reconstruction of the Triassic. Australian Jurassic Plants. Left is Agathis jurassica, right is Osmundacaulis sp. Here is the accompanying Jurassic reconstruction. Early Cretaceous Australian plants. Ginkgoites australis at left and Phullopteroides dentata at right. Fun fact; this is where I first learned that seed ferns survived into the Cretaceous, as most dinosaur books simply seem to forget about them after the Triassic period. I guess you can also see my hand here. That's one of the annoying things about all of these items being behind glass; it's difficult to take nice photos of them without getting yourself into them. Still, it's better than the alternative, as you'll see later... Here is the Early Cretaceous reconstruction. Weird how there is a stegosaur, when stegosaurs easily reached their peak diversity and abundance in the Jurassic. Only one plant is in the Late Cretaceous cabinet, and ironically it is unidentified. The final reconstruction, which is of the Late Cretaceous. Interesting how this is the only one to not have a Theropod or Sauropodomorph. Non-Dinosaur Mesozoic Animals Opposite to the plant display, there is a section dedicated to the animals the dinosaurs shared their world with. Interestingly, this section starts out with an Eoraptor lunensis cast, to highlight certain features unique to dinosaurs, such as their hollow hip sockets. You can see parts of the herbivores and carnivores sections in the background. Over my many trips, I often seem to gravitate to this specimen, as besides the Jobaria, Giganotosaurus and Archaeopteryx it is easily the one I have the most photos of on my phone (obviously more than two, don't want to clutter the page). Properly starting off our journey on non-dinosaurs is a display of terrestrial animals. All fossils are real except stated otherwise: Skull of an unidentified Dicynodont found in Zambia. Cast of Rhamphorynchus muensteri from Solnhofen in Bavaria, Germany. Parotosaurus wadei skull from Brookvale, NSW, Australia. Clarotitan andersoni from Brookvale, NSW, Australia. There is another specimen in a different gallery which I took a better picture of. Cleitholepis granulata from Somersby, NSW, Australia. Cavernericthys talbragerensis from Tralbragar, NSW, Australia. It is overlaid on a leaf. You'll notice some other fossils from Tralbragar in the Jurassic plants cabinet, as well as in another gallery. Left is a nymph of Promimara cephalota, found in Koonwarra, Victoria, Australia, and right is an unidentified cockroach from Brookvale, NSW, Australia. Aeschnogomphus sp. from Solnhofen in Bavaria, Germany. This specimen was special, but very annoying to get a photograph of. Cast of lower jaw of Teinolophis trusleri, a monotreme mammal found in Inverloch, Victoria, Australia. According to the label it is the oldest known mammal in Australia, even older than Steropodon. I'm going to start a new post now so that I don't run out of space.
  2. Hi Everyone! I acquired this Kem Kem gem a few months ago. I'm pretty certain that it's a Spinosaurid Caudal, which would have been really cool by itself since it's one of the better ones I've seen, but what really sticks out (or in) is a very large unique looking hole on one side. The bone is about 9.6 cm long and hole by itself is roughly 3.5 x 2.7 cm wide and 1.3 cm deep. Damage on Kem Kem material isn't uncommon, but the bone surface flows into the hole as if it was made before fossilization. The big question I have (aside from a second opinion that I'm not just seeing something much cooler than what is there), is pre or post mortem and potential causes. I don't think it's a bite mark. While I have seen really big Spino teeth with that cross section there isn't any damage to the other side and I feel like a tooth that size would punch a hole straight through the bone rather than just leave a 1.3 cm deep hole. Same with potential injury from a large spike of some sort. I don't think it's cancer since there's no excess growth. The main thing that comes to my mind is a really nasty infection with a large abscess, potentially caused by a minor injury that got infected (Spinos loved swimming in some nasty swamps after all). But as with any claim like that it's pretty important to seek out a second opinion. So what do you all think? Any insight is appreciated as always!

    Desmostylian teeth, pathology?

    Dear fellow forum members, some time ago I acqured two desmostylian teeth, presumably Desmostylus hersperus. Only Info I got is that they are from california. I have been wondering if the smaller one shows some kind of pathology r if it is a juvenile unerupted tooth? By the way, could the chambered structure circled in red be a sand dollar? Best Regards, J

    Unknown Bone

    I found this bone in a creek in Edmonton, Alberta, Canada. I have asked some hunters and farmers what it could be but nobody seems to know. It appears old but modern. There looks to be a suture mark or perhaps an old fracture or some pathology. I would appreciate any insight into what bone this may be. Or where I might look to find something to compare? Thank you.
  5. Aquired a big megalodon tooth who seemed to have certain deformation/pathology to a certain extent. However, it looks like serrations has started to split off in two directions? I'm not familiar with this at all. Anyone who is more familiar with megalodon and shark teeth that can help?

    Pathological Cockerellites liops (Cope, 1877)

    This is a Cockerellites I found last year and had prepped out. It came out in a pretty gnarly split and had to be glued back together and prepped. With slight restoration it turned out very well. Looking closely at the anal fin spines, you'll notice the pathology, this specimen has 4 instead of the usual 3. This is most likely a pathology of a Cockerellites liops instead of a new species.
  7. Just wanted to share a seriously pathologic hastalis from a recent trip in Virginia…
  8. Here by my new Spinosaurus Aegypticus tooth from Taouz, Morocco. It is 4 1/2 inches. The colors are less common than your regular Moroccon Spinosaurus teeth. It has 0 restoration done to the tooth, and the quality is very high. Which I find special about this one. Noticed some slight patho and serrations on this tooth too? Could someone explain the patho perhaps.
  9. Here is my new wood grain Tyrannosaurus rex tooth. Found in Hell Creek, South Dakota and just shy over 1'40 inches. I really like the split with the serrations. Makes it extra special for me.

    Pathological Brachiopods!

    Last May, my husband and I went collecting in the Cincinnati, OH area while on vacation. I was largely focusing on collecting microfossil matrix, while he was looking for interesting macro specimens. I asked him to collect a bag of the small brachiopods that were everywhere around where we were hunting. He gathered a few dozen pieces, and when I cleaned them off, I noticed a few odd ones. First, the normal examples. Cincinnetina meeki (Miller): And it looks like two photos at this resolution and size is the limit per post. More to come!
  12. Hello All! I am lucky in that I have two T Rex Toe bones to decide from. One is of an adult (5 inches and heavy) that may have pathology on it. Perhaps bitten and as such healed itself "gimpy" (top right). There is erosion through the bone and so the definition is much less. And it is possible that the loss of the section is to erosion but the collector believes there to be pathology. The other is a juvenile toe bone (3 1/2 inch). It is in great condition with good definition. Irrespective of the price, I am interested in you all helping me decide which one to choose. Thanks!
  13. Hello everyone, I know this may be a stretch, but I remember a thread on here that contained a paper or poster on Megalodon pathology. It’s basic claim was that there was a correlation with tooth size and rate of pathology. I’d like to read it again, but I can’t seem to find it. I was wondering if anyone else could remember it or find it. Thanks!
