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！

New long-necked polycotylid plesiosaur discovered in Wyoming
pachy-pleuro-whatnot-odon posted a topic in Fossil News
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.

Possible Plesiosaur/Pliosaur Tooth from UK
Alston Gee posted a topic in Is It Real? How to Recognize Fossil Fabrications
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?

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

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)

Possible plesiosaur’s jaws?
Sergiorex posted a topic in Is It Real? How to Recognize Fossil Fabrications
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.

Goal: collect all Pierre Shale formation main fossil specimens. During my fossil hunting trips I collect a lot of different fossils but never take the time to figure out what it is exactly. Here I will record my trips and finds but more importantly try to identify what it is. This list will encourage me to not just look for the big marine reptiles but also smaller things I normally ignore. I understand how unrealistic this goal is but it's fun. Any feedback or suggestions are welcomed! Specimens shown on wiki for Pierre shale.

Morocco's Sahara fossils show 'monster' could have lived in Loch Ness
Denis Arcand posted a topic in Fossil News
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 -
This fossil has many grooves, holes and structures. My only guess is it's a part of a skull of mosasaur or plesiosaur. Any ideas? Or good reference pics of skull parts for comparison? Thanks
-
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.

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^^

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!

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
pachy-pleuro-whatnot-odon posted a topic in Fossil News
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. -
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!

Hey can anyone help me to id this tooth please it from Russia Belgorod region it's pliosaur or ichthyosaurus
-
Found in NJ Cretaceous stream. Any suggestions? Looks like a partial vertebrae. Possibly Plesiosaur? Or even Dino?
-
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?

Ozan Formation polycotylid plesiosaur tooth fragment
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
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)- 4 replies

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!

I was able to obtain a couple of fossils found on the western coast line of France. The first one is presumably a piece of paddle bone from the upper tithonian, found between Wimereux and Cap de la Crèche. It measures about 220 x 160 x 65mm. Very heavy. The second is a vertebra found between Cap d'Alprech and Equihen (Tithonian). Measuring about 80 x 65 x 35mm. Could these be pliosaur or rather plesiosaur fossils? I'm sure they are too worn to identify better than sp.? Thanx for notes!

Hi all! I've been really busy creating all these watercolour illustrations based on fossils from the Jurassic Coast. Here we have an Ichthyosaur, a Plesiosaur, an Ammonite, a Scelidosaurus and a Belemnite. There will be a few more to come soon...
