    Volga in November

    Hi all! Another report in continuation of the previous ones. This time I had 2 days to visit the site and used them to monitor my preferred 3 km of the shore. It was literally the last days of autumn, so by the end of my stay snow started to slowly cover the place for the 5 upcoming months. The water level was a bit lower than in 2020, but much higher than last year. This time 3 boars on the shore: one of them
  2. Hello everyone! I found this tooth online. It's from a Plesiosaur. Zarafasaura oceanis. From the Ouled Abdoun Basin, Maastrichtian. I have never seen these teeth have root. Is it real? Cheers. - Adriano.

    Plesiosaur?

    Hello, everyone. I have a Moroccan vertebrae fossil purchased in Tucson. The label is Plesiosaur. Is it real? If it was true, what kind of Plesiosaur would it be? (Elasmosaurus?Kronosaurus?or…… and Maybe everything I said didn't exist there. I'm sorry I'm not familiar with it) The last question is, which is the correct position of these vertebrae in dinosaurs ? Be grateful for any help!
  4. A new polycotylid plesiosaur has been recovered from the upper half of the upper member of the lower Maastrichtian (Late Cretaceous) Pierre Shale Formation of Wyoming: Serpentisuchops pfisterae, the snake-like crocodile face. The interesting aspect to this new discovery is that this polycotylid, contrary to most other known members of this clade (that is, all with the exception of the Turonian Thililua longicollis and Manemergus anguirostris from Morocco), has a elongated neck, convergent on those of elasmosauridae. The pertinent article can be found here: Scott Persons IV, Street and Kelley, 2022. A long-snouted and long-necked polycotylid plesiosaur from the Late Cretaceous of North America.
  5. Hi, I always struggle to tell the difference between a Plesiosaur tooth and an Ichthyosaur tooth. This tooth comes from Goulmima in Morocco (lower Turonian) so I believe it is a Plesiosaur tooth (possibly a Pliosaur tooth), but wanted to confirm it here. The tooth is 4.2cm in length and retains the ridges on the tooth which I think is how you might tell the difference between Plesiosaur and Ichthyosaur. Thank you!
  6. Both of the teeth came from the White Limestone, Traditional Layer, Great Oolite Series, Bathonian of Oxfordshire, UK. Any thoughts on the identity of these teeth? Are they crocodile teeth or plesiosaur/pliosaur teeth?
  7. My daughter and I have just been down to Penarth in Wales; we’d nearly given up on the place when I spotted this tooth on a slab. It came from the Jurassic layers where I know ichthyosaur and plesiosaur material is regularly found. I’m thinking it’s the latter of these but I have very little knowledge to back this up. Can anyone tell me what the tooth belonged to and maybe even narrow it down to a species. Many thanks for looking IMG_3688.MOV

    Muffinsaurus Collection

    I don't know if I'm posting this in the right place but I figured I'd show off my collection. I don't have many of my own finds cleaned up enough so I'll start with the ones I have bought or have been gifted. I don't have much, but I'm proud of what I do have (except that spino tooth). Note: I just figured out how the label pictures. If I made any mistakes please let me know. Zarafasaura oceanis Zarafasaura oceanis (Unknown fish jaw) Prognathodon Spinosauridae Amber with ants in it (I got it at a gift shop back in 2017 and have no information about it)
  9. Saw this for sale, not sure whether it’s real or what species of animal it came from, but looks like plesiosaur? It was “purchased at the Tucson Gem & Mineral Show.“ it weighs 6.1 pound and the bottom jaw is about 9.5 inches long, the top is about 9 inches.
  10. University of Bath researchers said it was "plausible" that a plesiosaur could have survived in the Scottish loch. https://www.bbc.com/news/uk-scotland-highlands-islands-62317648 The study was published in Cretaceous Research
  11. I think is marine reptile. Poorly fossilized. Also how to post many pics at once?
  12. 2ft long block. found weathered and near other marine reptile and fish fossils. Couldn't find any more parts to this. Is this a tail? Seems small compare to other mosasaur verts I find.

    Damaged Plesiosaur Tooth

    First of all hiiiii this is my first post on this forum Soo, I live in germany and am doing some vacation on the beach rn. I found a guy selling gems and fossils. I bought this lil specimen. After I bought it he said its the most rare thing in his inventory lol. According to the guy the tooth is from a plesiosaur, unknown if there is more in the matrix(Atleast there are some shells but thats not the point of this post anyways.). All I got about where its from was "south brazil". Facts list: >Plesiosaur tooth presumably >partially damaged >From (southern) Brazil The measurement in the pictures is in cm. Id really appreciate if anyone could help me identify this one, already thanks in advance^^

    Polycotylid lower jaw?

    Hi, Saw this and I think it is a small lower Polycotylid jaw (possibly from Manemergus or Thililua) and I wanted to get some opinions on it. It comes from near Goulmima in Morocco and is 42cm in length. Thank you!
  15. Hi there everyone! I acquired this plesiosaur tooth specimen from Oued Zem, Khouribga, Morocco not too long ago and I couldn't help but be fascinated by all of the different fossils found in the single piece of matrix. The front of the specimen contains a beautiful plesiosaur tooth with what I believe is a fish vertebrae and other fish material. On the back, the specimen is riddled with small shark teeth as seen by an exposed root and various exposed crowns. Though I'd greatly appreciate a positive ID on the plesiosaur tooth, I'm really more interested in the identification of the other fossils surrounding the tooth. I'm aware that accurately identifying the other fossils may be nigh impossible, but I'd love to hear what you guys think and I welcome any guesses you all may have just for the fun of it. Cheers, Rik

    New longirostrine pliosaur described from the Oxford Clay

    Hi all, Just came across the exciting news that a new pliosaur genus and species has been described from the Callovian stage of the Oxford Clay near Yarnton in Oxfordshire. Dubbed Eardasaurus powelli (Powel's Yarnton lizard), it's a longirostrine thalassophonean pliosaur that is slightly more derived than Peloneustes philarchus (with which it shares numerous anatomical features) and forms a sister taxon to "Pliosaurus", Simolestes, Liopleurodon, Pliosaurus and brachaucheninae. A feature of particular interest in the dentition of this new species is the presence of connecting carina-like apicobasal ridges on some of its teeth. The article describing Eardasaurus powelli can be found here.

    Monster Plesiosaur Verts

    I said to myself at the start of the year, I’d try to find more bone, rather than just ammonites. Well, last week I hit the jackpot of rarities here on the Yorkshire coast. Plesiosaur vertebrae. Now, marine reptile bone is quite rare here as a whole, Ichthyosaur comes out every now and then, but plesiosaur, pliosaur, and crocodile are MUCH rarer. So imagine my shock when I see a vert, pick it up, and it’s plesi. Then, I find a second, that slots on perfect, then, a third about ten metres away that also fits together. Straight onto the beach they went. I penned off the little shale matrix the had one them, then it was straight into the blasting cabinet to be abraded. I can’t even over exaggerate how easy this prep was. First vert took a total of twenty minutes of abrading and was finished. Second vert took about the same amount, and the third took around an hour due to some pyrite limestone, that seemed to because from a bivalve that are washed inbetween the rib attatchments. The preservation is ridiculously good, like, you don’t get much better for here. I have been back today to see if any More have come down, but my trip was fruitless (picked up plenty of ammonites of course). I think they’re sat in the cliff going inwards, so just a case of waiting for them to fall, they’re around 50ft up in the cliffs I believe. Hopefully I’ll get more soon!

    NJ Cretaceous Partial Vert ID?

    Found in NJ Cretaceous stream. Any suggestions? Looks like a partial vertebrae. Possibly Plesiosaur? Or even Dino?

    Possible NJ Plesiosaur tooth?

    Found in NJ Cretaceous stream. The striations stood out to me. Even though its small (about 3/4-inch) could it possibly be a plesiosaur tooth?
  21. I recently acquired a collection of Cretaceous fossils from the estate of a Dallas, TX, collector—mostly shark teeth. Unfortunately, they didn’t come with location info, though they were most likely collected in North Texas. I could use help identifying two of the non-shark fossils (and probably some of the shark teeth too, which I may post later). The scale in these photos is in centimeters. #1 - Is this a plesiosaur tooth? There are two cutting edges, on opposite sides of the tooth (see the third set of photos, top and bottom). #2 - I have no idea what this is. Thanks for looking!

    Ozan Formation polycotylid plesiosaur tooth fragment

    Hi all, I got this partial tooth in last week which I bought from a US-based seller claiming it was a mosasaur tooth - though I bought it already suspecting it is not. Having since received the specimen, I can confidently say it's plesiosaur, more than likely polycotylid, as the ornamentation exhibits dense packing of fine striations lingually and a near complete drop-off of striae labially with only some small ones remaining near the base of the crown at great intervals. In a lot of ways this type of ornamentation is reminiscent of that of Jurassic pliosaur teeth. But as the tooth is said to have come from the Ozan Formation, which dates to the Campanian and Maastrichtian and therefore a time after pliosaurs had gone extinct, it's obviously not possible for the tooth to be pliosaur. It's morphology would moreover be somewhat strange for a brachauchenine pliosaur, as the striations are indeed very fine. Cross-section of the tooth is sub-circlular without carinae but with a slight lingual curvature. Now my question here would be if anyone knows what species this tooth might be attributable to. From my own experience identifying Jurassic pl(es)iosaur teeth I know this can be quite a challenge, but also know that there's often some minute indicators that can still help do so anyway. My current candidates, based on regional occurrence and time-bracketing would be Dolichorhynchops and Polycotylus. I, however, lack the proper geological and geographical resolution to narrow genus or species ranges down further. @JarrodB @Jared C @JohnJ @Jackson g (and anybody else who might be able to help out)

    Biritish Kimmeridgian plesiosaur tooth

    Hi all, I bought this Kimmeridgian plesiosaur tooth from the Faringdon sponge gravels a while back. It came identified as Colymbosaurus sp.. At that point, I simply accepted this identification, seeing as the teeth of Colymbosaurus (or, at least, what's suspected of being Colymbosaurus) were already known from the Etches Collection and I didn't really have the means to verify the ascription from online sources. Today, however, The Etches Collection posted a video on Kimmeridgian plesiosaurs on their YouTube-channel, which make it abundantly clear that my specimen doesn't correspond to Colymbosaurus (video referenced below, as is a photographic excerpt of the teeth). The teeth of Colymbosaurus are not only subtrihedral but gracile in shape, they also have very strong striations - much stronger than in my specimen and almost pliosaur-like. The striations on my specimen, on the other hand, are way more similar to those of the Oxford Clay Tricleidus seeleyi, with very fine striations all along the tooth, a round cross-sections and (obviously) without carinae (just to rule out marine crocodile). My question now is: can my tooth be identified as to species or even genus? Could it be that the temporal range of Tricleidus extended into the Kimmeridgian? Might this tooth belong to Kimmerosaurus? Steve mentions in his video that there are more plesiosaurs that remain to be described from the Kimmeridge Clay, so, with that in mind, should I just classify mine as "cf. Crypticlididae indet."? Any ideas and suggestions welcome, but will just also tag @paulgdls and @DE&i.

    Pliosaur? From Morocco

    Here is a 7 cm long tooth, claimed to be pliosaur. What do people here think? It's from Morocco, unsure where specifically. @pachy-pleuro-whatnot-odon

    Not sure if fossil?

    Hello! Indulged my hobby a little this weekend (4-7 Mar) and headed to Lyme Regis for some sunny ammonite hunting. Found this while digging on East Beach there… I’m nowhere near experienced enough to determine if it’s even a fossil at all, but it was such an odd shape and I thought I’d ask! About 1 3/8 inch (3.5cm) across and approx 1 inch (2.5cm) thick. Found 5 March 2022 on East Beach, Lyme Regis, Dorset, UK. See photos below for details. Thank you everyone!
