  1. Back to childhood

    Hi all, This is a report on my recent fossil hunting trip to Ulyanovsk region, Russia, inspired by the most interesting stories and pictures I read and looked up here. I took many photos myself in an attempt to convey the atmosphere. I dont think you know much about Russian fossil hunting spots, so I start with a short description of the place I visited. Ulyanovsk Oblast (region) is located in the middle Volga basin and much of its territory is covered by a part of the Kuybyshev Reservoir (largest in Europe). Its sometimes called Kuybyshev sea and for a reason: with distance between coasts reaching 30-40 kilometres, unless the weather is super clear, the other coast is not visible. Add frequent stormy weather with high waves and the impression of a sea is almost complete. Creating the reservoir lead to big scale soil erosion with prehistoric layers coming to surface. They are constantly washed away with fossils becoming available by simply walking along the shore. Basically all the western coast in the region is covered with late Jurassic-early Cretaceous deposits, mostly Kimmeridge clay (155 ma) with Hauterivian layers (130 ma). The fossils are good quality and do not require any preservation except the fact they are often pirytised thus subject to oxidation. The place is (or was) very rich in sea fossils: ammonites, belemnites, reptile remains etc. They say at least 3 reptile genus and 20 species were recentlydescribed by the remains found here, for instance Undorosaurus (name derives from local village's name), Makhaira rossica, Luskhan etc. Paleontology sections of three regional museums (Ulyanovsk, Tatarstan and Samara, with some going to Moscow) feature impressive exhibits taken from here including compete or almost complete sea reptile skeletons. (You can see some of them here, here and here). Unfortunately there have been too many guys looking for fossils and fine pieces of local yellow calcite to sell, passing like a vacuum cleaner picking up everything valuable from early spring to late autumn. By the way, a nature reserve (zakaznik on a regional scale, which itself is pretty weak) was created here in 1980s right to counter this situation, but with lack of effort it turned into a joke. The local village museum was charged with enforcing the reserve status - let's assume its management did not have the funds or personnel to prevent anybody from picking up fossils (not to assume they were picking them up themselves alongside the poachers without reporting them to the public). Anyway as a law-abiding citizen, I was collecting outside the reserve's boundaries. Here the fossil-rich shore is marked in green, the reserve in red and 3 main fossil-related villages in blue. I used to spend vacations in a local sanatorium as a schoolboy and accumulated quite a collection of local thingies ( I sure was fascinated by my findings and paleontology in general). In April I decided to spend there a couple of days again. The receptionist asked if I had been there before. Only in childhood, I replied. She laughed - nothing had changed since then. Well, I hoped so:)
  2. Hi, I was wondering if this tooth could be from a Pliosaur. It is from the Goulmima area in Morocco. It is 8.8cm in length and some of the striations remain near the tip (the size is what makes me think Pliosaur). Thanks.
  3. Mosasaur, Plesiosaur or Spinosaur

    Purchased from online. Morocco fossil. Are they Mosasaur, Plesiosaur, Spinosaur or other species? Need help for ID, Thanks!
  4. NJ Cretacous Whose tooth is this?

    NJ Cretacous hunt today, found this tooth in a deep sift. Has a tiny bit of enamel left on it. Any ideas? Its about 1-1/2 inches long.
  5. Been a long time, finally got out for a bit and found my 3rd Plesiosaur vert along with some others. Also the first snake encounter of the season. This guy was only a few feet long. 49 degrees with 20 mph winds. Warmer days ahead! Late Cretaceous 80 mya
  6. Moroccan Verts

    @snolly50 was nice enough to send me a mess of a Moroccan concretion to play with recently. It started out as what appeared to be bits of vertebrae poking out of the block. After about 4 hours of scribing with my ME9100, I had uncovered a few scraps of bone but no centra were evident. The natural crack that you see opened up from the vibrations of the scribe and no robust bone was evident in the crack either. With John's permission, I began exploring the back of the block, hoping to find something worthy to prepare. Bingo, I found some bone. The crack happened to peel through a small section of the centra rather than through a full cross section giving the appearance of a lack of large bone in the concretion. 4 or 5 hours later and the verts were mostly exposed. Unfortunately, this concredtion had a thin layer of softer rock on the outside and a significantly harder inner core. The matrix is MUCH harder than the bone and I fought the bones trying to crumble the entire time. This has copious amounts of Vinac on the bones to stabilize them. At this point, the ME9100 is almost making no progress on matrix removal. Enter the Super Jack scribe. This beast will plow through the matrix. It ultimately saved me around 12 hours of scribe work on this project. The one thing you have to be careful of is the increased vibrations to the block with the more powerful scribe. I spent more time consolidating and aggressively applied Vinac to any bone as it was exposed. Prep progressed quickly with me alternating between the Super Jack for bulk matrix removal and the ME9100 for close to the bone work. Including the exploratory time, I have 16 hours into this prep at the finish. I left some of the tool marks on the matrix rather than completely smoothing it out because I think it highlights the rugged nature of the piece and most Moroccan stuff has tool marks. The ones I have seen that are totally clean look off to my eye. It would be like @RJB leaving tool marks on his crab concretions. None of them have it so if they were there, it would look wrong. Here's the final product.
  7. Hi everyone! New member here. I am very excited to make my first post. So I came across a vendor today with some cool stuff, but I wanted to run some photos by the forum members first to see: 1) if you think they are real or fake. 2) how much would you expect to pay for a piece like that. Thanks for the help! Item #1 - Mosasaur Jaw To my eyes, this item looks legit as the teeth don't seem to be floating above the jaw with composite all around it, or teeth pointed in different directions. BUT...I know fakes are good and I am relatively new to educating myself to fakes vs real. Item #2 - Another Mosasaur Jaw (top and bottom) Also looks pretty legit to my newb eyes. But I am worried both top and bottom jaws in that position are too good to be true. Item #3 - Croc Skull? My gut reaction is fake...mostly due to the matrix looking like it was smeared on like cream cheese. Item #4 - Plesiosaur Skull and Neck It's apparently from goulmima southern morocco. Sadly I don't have more pics, as I didn't want to handle it and move it around. But I was able to get down low and see that it does have it's teeth. I just couldn't a good picture of it. :-\ The closest comparison I could find was this plesiosaur head/neck from an archived auction house website image. But the matrix around it seems the same.
  8. Plesiosaur/Ichthyosaur teeth

    Hey! Thought I would share a photo of my British Ichthyosaur and Plesiosaur teeth (and 2 Plesiosaur ribs and a shark tooth!) Most of these fossils come from South Wales except for the large tooth. It is suspected to be from Eurycleidus and was found in Aust, England. Plesiosaur teeth from the UK are apparently very rare.
  9. Saw this for sale, and was wondering if these are Plesiosaur vertebra's?. The fossil is from the Goulmima region in South - Eastern Morocco. Thanks.
  10. Current Prep Thread

    So, what do we all havecurrently on the prep table? Be interesting to see what challenges await everybody. My current piece is this bone block, most likely ichthyosaur rib. A few scattered ammonites from the genus Dactylioceras sp. if expecting to probably found more bone further in all being well, probably a vert or two and some more ribs.
  11. New Zealand marine reptile vertebra

    I've got this very worn vertebral centrum from the marine Conway Formation near Oaro (Late Cretaceous; about 79-73 Ma) on the south island of New Zealand. The only two logical candidates are plesiosaur or mosasaur from this formation, both of which are known here. There are characteristics of both groups seen on this bone which is tripping me up a bit. One end face seems a bit concave and the other more convex which is a mosasaur feature, but then there also looks to be two distinct holes on the ventral side (see photo three) which could be the paired foramina that are characteristic of plesiosaur vertebrae. So i am left scratching my head! What do others think? Front face Dorsal view Ventral view (note what look like paired foramina) Lateral view
  12. Plesiosaur femur or humurus?

    Can anyone tell if this is a plesiosaur femur or humurus? Or if not, have any thoughts on what it could be? From what I can tell it seems to have a slightly shorter/heavier curved length, and a more symmetrical curve than most plesiosaur bones Ive seen. I think it looks VERY close, but the slight differences I'm seeing are consistent with almost every plesiosaur bone I'm seeing, which makes me think the slight difference is a tell that it's not. Also, I don't see the ridges on any plesiosaur bones, but I don't know if that's natural to the bone, or from damage from fossilization at some point, but it does look natural to me. Sadly I do not know where it's from(yet), and I don't know yet if it starts to flatten towards one side, which I believe is an absolutely necessary feature. Hopefully I can find out and add that info, but I'd imagine it could still at least potentially be debunked as a plesiosaur bone in the meantime.
  13. Missing pliosaurs?

    This started bothering me from lack of fossils for sale(and tooth prices when they are), and although this is far from anything scientific or reliable, I feel like I hear about plesiosaur fossil finds significantly more than pliosaurs finds(im not really sure how to begin searching for that kind of compiled info). Is there a reason pliosaurs seem to be so rare? As far as fossils for sale, the only thing I can think of, other than pliosaurs being just plain rare(super rare when compared to the number of plesiosaurs), is that for some reason everyone just mistakes/assumes pliosaur fossils are actually from plesiosaurs.

  19. NJ Cretaceous & Mammal Teeth

    Hello everyone, this is Trevor. I have been meaning to post this for a long time and finally got around to doing it. I would appreciate help identifying these finds. Also, stay tuned I have a trip report coming out later this week, probably Friday. What type of ammonite is this? (middle)

  21. From a plesiosaur?

    From all the comparing Ive done, i think it almost looks exactly right, except I haven't been able to find any vertebrae with the things on the bottom(chevrons?) shaped like that; that 90degree bend. Is that familiar to anyone? Is that something that appears on plesiosaurs or not? (no better angle of the chevron(?)on the other side)
  22. nj cretaceous stream plesiosaur vert?

    Finally got back out to the streams today and was a beautiful day and great finds,,,,,my wife found what I believe to be plesiosaur if you guys can give us some info please...............thanks
  23. Elasmosaur jaw?

    Could this be a plesiosaur(elasmosaurus) jaw? I tried comparing but it's hard to see the picture of jaws in ideal positions and angles and such. Also, with so many extreme teeth it can be hard to see perfectly in a lot of pictures. (Location-wise and all, it could be, this is just about the physical jaw itself)
  24. Nice surprise today. Only my 2nd Plesiosaur vert in my first 4 years. Ive got about 150-1 ratio Mosasaur to Plesiosaur verts. It’s small but in great condition North Texas Late Cretaceous 86-90 mya
