  1. When I caught wind of @jnoun11's traveling exhibit coming to Canada, British Columbia of all places, I made sure to book it down to the Vancouver Aquarium immediately! It was the most incredible display of Moroccan fossils I have ever seen and far greater than any permanent museum galleries! Of course I spent most of the time at the mosasaur section, finally getting the chance to see the marine reptiles I work on fully reconstructed in all their glory! The best part was seeing the species of mosasaur @pachy-pleuro-whatnot-odon @Praefectus and I named on display for the whole world! Such a great feeling! The skull of Hainosaurus boubker stood proud along side Thalassotitan atrox and the skeletons of Mosasaurus beaugei, Halisaurus arambourgi and Zarafasaura oceanis (plus some turtles). The murals in the back illustrated the diverse community of the phosphates in an active, warm sea environment which made you feel like you were right there swimming with them! The info boards were great and very informative with a fun "Monster Level" gimmick to show how fierce these predators where in their environments and times! Unfortunately Hain and Thalass were still under their pre-2022 names of Tylosaurus and Prognathodon anceps (plus using their smaller size estimates) which hopefully one day will be updated. I purchased a seasons pass just to revisit this display several times this summer while it is still around! Here are some photos of the mosasaur section (plus Spinosaurus) I took with my good camera!

    Possible Captorhinus Fossil?

    I found this 152mm x 101mm x 25mm piece of what appears to be a limestone fossil. Other minerals found nearby were chert and loads of limestone. Found in Wyoming on Medicine Mountain on the side of the road where there is plenty of rock fall every year. Scales/scutes range from 6.35mm in oval length to 19.05mm, all scales/scutes are about 6.35mm in width and apart from each other. The closest scale/scute pattern I have seen on the internet is the Captorhinus lizard, very well preserved in a cave. Anyone have any ideas? I appreciate you all!

    Unknown tooth Solnhofen Germany

    Unknown tooth (6 mm) from Solnhofen (Mühlheim, Lkrs. Eichstätt) Germany., no carinae are visible. I think about fish, anyone have an idea? Fish or reptile? Unfortunately no better photos.
  4. I found these in NorthEast Iowa Fayette County, so that is the Paleozoic era ( I can't download the NorthEast Iowa fossil guide for whatever reason) They are certainly broken. The first one appears split in half. Makes it looks like a turtle or dinosaur lol. The second fossil starts on picture 11. The bottom looks the same and sides are covered in what appears to be moss work. Both limestone/chert and same area, not but yards away probably on a different day. Fayette County Iowa. I have a couple fossils and I can't figure it out. Probably just fossiliferous Limestone type, but I'm very unversed in fossils. It looks like something is coming through both of them. One shows what looks like skeletal structure. I need to clean them as they are hard to see. The first one shows the holes as a coral the second one shows more of silicified bones or skeleton ( it's probably not , I am seriously clueless lol) Please and thank you for your help as I have no where else to reach out.
  5. I managed to grab a couple hours at Rock-a-nore, Hastings this morning. This is my usual hunting ground and the material here is Wealden, early Cretaceous and around 140 million years in age. Not having a lot of time, I didn't work a long stretch of the coast and only made it as far as Ecclesbourne Glen, a couple of miles maybe. I found the usual couple of Tempskya tree fern trunk samples but, having ample specimens already, these were left in situ for others to find. I came away with a couple of specimens, a small fragment of reptile bone and something poking out of a rock which I cleaned back at home to reveal what looks like a partial fish rib or spine. This is actually a good haul for the location as I often leave empty handed. That's not to say that I haven't found anything, just nothing that adds anything to my collection. Here's the view prior to accessing the beach. Looking east towards Dungeness (the nuclear power station is visible in the distance). The terrain can be hard going (especially when you've had ligament replacement knee surgery last December) as it's a mainly pebble beach with cliff debris and many large boulders (a lot of which are slippery at this time of year). The cliffs are dangerous and prone to constant falls and so best avoided as there's a constant clatter of falling material. That said, it's wise to keep an ear on what the nesting sea birds are doing on the cliffs as they become extremely agitated when the cliff is about to move substantially so there is some warning. I have twice in the past had to dodge sections the size of a family car falling from the cliff which is why I prefer to beach comb these days. The site is also an SSSI and as such, removing anything from the cliff or footprints from the beach (unless loose and portable) is a criminal offence. The suspected fish rib or spine. Reptile bone fragment. The side that gives the game away - clear vessel structure. The sample alongside a very similar sample found about a month ago in the same general area. Bone preservation at this location is extremely variable so anything similar is invariably associated or of the same origin.
  6. Howdy! I've seen this ichthyosaur paddle for sale for a while. I don't know enough to say that it's real. If it is, I'd love to have it. Geological information: Triassic Guanting Formation, Ghizhou, China. Any help is appreciated.

    Help identifying ?

    I found this at my Grandfather's Farm right after They had A Excavator there that they were using to create a one acre pond. It's located in southwestern Ohio. There were lots of other fossils In that area as well, I've just never seen any that resemble a frog head quite like that. I would love to have some information about it. If anybody could help that would be greatly appreciated ! Thanks!

    Woodbine Plesiosaur? Leptocleididae?

    A tooth I recently pulled from my Woodbine honey hole keeps getting better the more I look at it. I originally thought it was just a really big crocodile tooth of the species Woodbinesuchus byersmauricei, a common find for the site. After cleaning it today, I noticed it was pretty different and am now 90% sure it's a plesiosaur tooth, perhaps from the family Leptocleididae (as opposed to Polycotylidae or Elasmosauridae) and maybe with some real scientific significance! Stay with me here... Crocodile teeth are pretty common for the site. So why do I think this isn't one? Besides being quite large for a croc, the 12 enamel ridges on this specimen vary in shape and are spaced out whereas my crocs typically exhibit tightly spaced, uniform ridges numbering in the many dozens. The ridges on the "plesiosaur" are restricted to the lingual side. My crocs typically have ridges spanning the entire circumference of the crown, though they sometimes peter out on the labial side as well. Another significant difference is in the sigmoidally curved crown which is normal in plesiosaurs and generally not seen in crocs. "Plesiosaur" (L) and Croc (R); Note the significantly different enamel ridge characteristics. "Plesiosaur" and my complete crocs. Quite large relatively speaking. It's crown is about 20 mm long and 6 mm in diameter. Sigmoidal curvature in the crown. I am less sure of the familial identification and beyond. A quick google search for Cenomanian Plesiosaurs revealed an interesting article on freshwater Kem Kem Group Plesiosaurs (https://doi.org/10.1016/j.cretres.2022.105310) from more or less the same time (Woodbine = mid Cenomanian vs. Kem Kem Group = ?Albian-Cenomanian). What initially caught my eye was Fig. 5 where a handful of similar teeth are shown: Fig. 5 from the article. Leptocleididae indet. shed teeth. These are thought to be indeterminate Leptocleididae shed teeth for features shared with my specimen. The authors rule out Polycotylidae on the basis that those teeth are usually more robust. They acknowledge that longer teeth of Polycotylidae do occur, but the striations are finer than Leptocleididae. The authors contrast their teeth (and mine) from Elasmosauridae and Cryptoclididae by stating that those families have straighter teeth with more labio-lingually compressed crowns that create a strong oval cross section. My tooth and those shown above are sub-circular/slightly oval-shaped. Another point to make is that Leptocleididae plesiosaurs are UNKNOWN from deep water environments and are instead suggested to be nearshore specialists (Woodbine is famously nearshore with its crocs, Cretodus semiplicatus, and other nearshore fauna). On the other hand, Polycotylidae, the sister taxon, is a deeper water family. Hard to show a good cross-section because a chunk of root juts out of the bottom making it look more labiolingually compressed than it really is! Implications and Significance: One extremely interesting aspect of plesiosaur ecology that is highlighted by the article is their strong presence in prehistoric freshwater ecosystems. Plesiosaur teeth of the family Leptocleididae are commonly found in the Kem Kem river systems which isn't crazy given they are thought to be nearshore specialists. The authors note that contemporaneous marine deposits have yet to yield Leptocleididae material, which makes one wonder: were they freshwater specialists unable to live in the ocean? I would've been inclined to assume they could survive both fresh and salt given my preconceived notions on plesiosaurs, but there is a lack of hard proof... Until now? If this is what I think it is... this may be the first evidence of Leptocleididae found in a marine deposit contemporaneous with the Kem Kem Group! Just the missing puzzle piece emphasized in the article. Reeling it back in- Keep in mind, a few hours ago I thought this was just a big croc tooth! Also, I don't know much of anything about plesiosaurs since I had never found such material previously. My head is spinning with all these new names. Hopefully you all can provide some clarity on this matter. @pachy-pleuro-whatnot-odon @Jared C @PaleoPastels. Feel free to tag anyone else you know who might have some knowledge on the subject!

    Fossil poo or rock?

    I bought this rock today just as an ordinary rock but it looks a lot like fossil poo from maybe a reptile or shark what i have seen. Its like a smaller version of meg poo but its brown. Any ideas?
  10. Found this recently in glacial till material in E Kansas. What I find unusual is the rather thick neural process- I’ve personally never seen anything like it. Any ideas, suggestions, or corrections are greatly appreciated; I’m trying to learn more about iding vertebrae. Measurements in cm/mm As always thank you everyone!
  11. Hello, I'm sorting though microfossil matrix from the Permian Texas red beds. I'm not very familiar with this area, but understand that there are shark, reptile and amphibian teeth in it. Could you point me to a guide or other literature relevant to this location or help me to understand most of what I'm looking at? I've found specimens as large as 5 mm and the smallest can't be picked up with my tweezers. This matrix has been sorted under a cheap microscope, so I'm sorry the pictures are rather blurry. Thanks for the help. (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11)
  12. I found this small and delicate, nearly intact marine reptile bone in Big Brook yesterday, and I'm wondering if anyone can identify it. The bone is just under an inch in length.
  13. Hello everyone, I found this at an antique shop and was wondering if it is real. There is very little info but to me it looks like it’s from China. The owner said it is from an old collection. Any help would be appreciated. Thanks!

    Crocodile Tooth?

    Any idea on what genus this could be from? Or, if it even is a crocodile after all? This tooth was previously IDed as a crocodile but others claimed spinosaurid. The tooth is late Cretaceous in age. It's from the Kem Kem Phosphate Beds in Touz, Kem Kem Basin, Morocco.
