    Plesiosaur vertebra

    From the album: Late Jurassic plesiosaurs from the Volga

    Probably Late Kimmeridgian. Ulyanovsk Oblast, Undory
  2. This fossil is in my collection for a while now. It is a quite heavy propodial found in Weymouth, Dorset, UK. It measures about 27cm in length. It's 12cm wide at the end, 6cm wide at the start. The centre part is 5 to 6 cm thick. I suppose it is Pliosaur (Stretosaur?), but it might be Plesiosaur instead? Thanx for opinions!
  3. Recent finds from my new year day adventure. Found these two teeth within 2 feet of one another. One I am confident in saying is a Mosasaur but the tooth on the right I need some help with! If anyone can shed some light it would be appreciated! Thanks
  4. Not sure if this goes here or in Fossil ID but I’ll post here… This is one of my latest online purchases, and one I had to snag because if this is what it’s supposed to be it’s a neat piece. But seeing as I can’t personally verify it myself, I thought I’d post here. This vertebra was being sold as Trinacromerum sp. While I doubt that just a centrum like this is identifiable down to genus, I would like to know whether or not this really is a Polycotilid vertebra. I think it’s likely because it’s a very sizable bone that’s not mosasaur, but just want to check. This fossil is, according
  5. Here’s a vertebra fragment I found in Cretaceous Black Creek group sediments of North Carolina. It’s not turtle, and it doesn’t look like any crocodile vertebra I’ve ever seen. That would leave mosasaur, plesiosaur, or dinosaur. Personally I think it’s mosasaur, but I could be wrong and it may not even possible to ID further. Any thoughts?
  6. Hi all, A couple of years ago I acquired a lovely pair of plesiosaur propodial bones from Lyme Regis. It was a matched pair of both humerus and femur. Today, when I was looking to make space in my cabinet for a new acquisition I had made, I discovered some odd dust next to the humerus that, on inspection and to my horror turned out to be pyrite bloom! I immediately removed the specimen from the cabinet, checked the other podial and nearby fossils, and used a tooth brush to brush of the most direct traces of pyrite decay. But the question is: what now? How do I ensure the propodial's prese
  7. Hi all, I recently decided to buy the below plesiosaur vertebra after having seen it for a long, long time. It dates to the Callovian of the Oxford Clay and was found at Peterborough. I suspect it may be attributed to Muraenosaurus leedsi, as it comes from a cryptoclidid plesiosaur, but is both larger and more elongate that the typical Oxford Clay Cryptoclidus vertebrae I'm familiar with. Supposedly coming from an old collection, it has a blackened exterior that doesn't cover the entire piece, with the more common buff colour visible underneath. As such, I expecte
  8. I have been thinking of buying this Plesiosaur tooth but I want to be sure its real and in well condition. Its from the Asfla Goulmima in Morocco. Turonian. Seller says its libonectes morgani.

    North Carolina plesiosaur or shark vertebra?

    I just recently found this bone in the Cretaceous Black Creek group deposits of eastern North Carolina. I originally thought it was an oddly shaped shark vertebra, but now I think it might be a worn plesiosaur vert. based on the images I looked up online. The overall cross sectional shape is elliptical, and the center looks much too thick for shark (doesn’t pinch in towards the center). Any thoughts? Thanks!

    Plesiosaur Tooth

    From the album: Robs Fossil Collection

    Lower Cretaceous Plesiosaur Tooth from Russia A very nice, well detailed tooth from this Cretaceous species of plesiosaurus Found:- Seversk Sandstone, Upper Albian, Lower Cretaceous, Stariy-Oskol, Belgorod Gebiet, Kursk, Russia Age:- 100 Million Years Old. Size = 2.2 cm long
  11. Hi, I have this tooth from the Akrabou Formation in Morocco, and I was told it is a Plesiosaur tooth most likely belonging to the genus Libonectes (An Elasmosaur). I just wanted to get an opinion if the id is correct or whether it could belong to something else like a Polycotylid. The tooth is just over 3cm in length. Thank you!

    Plesiosaur Tooth

    From the album: Robs Fossil Collection

    A Plesiosaur tooth from Khouribga, Morocco. Features a couple of repairs. Size: 1.69 inches Age: 65-70 million years Locality: Khouribga, Morocco
  13. Hi, any thoughts on this, from Lyme Regis? It is sold as Plesiosaur, but does anyone know if that is accurrate or if it is ichthyosaur? Thanks
  14. Hi all My kids and I found this tooth a while ago from the North Sulphur River in Texas. We can't figure out its ID and would appreciate any help. There is no carina; however, there are deep groves at the base. It appears cylindrical. After looking at various images, I can't tell if this is from a fish or a marine reptile like at plesiosaur. Images are below; the scale is 1 mm between the smaller hashmarks. Again, thanks for any help! Bret

    Plesiosaur or Pliosaur?

    Hey fossil friends. I found this worn vertebra earlier in the year When forum member @DanJeavs prepared this for me it revealed a very rare find for the Whitby coast. It is either a Plesiosaur or Pliosaur backbone. Anybody know what the difference is?
  16. Hi all! In continuation of the previous reports. Less text, more pics Bits of scenery:
  17. I’m looking for solid places to dig / sift in North Carolina, preferably near Greenville or Fayetteville! I’ve visited Green Mill Run in Greenville a handful of times, and upon researching I found a place called Phoebus Landing, but no specifics as to where it is aside from Elizabethtown and it being on the Cape Fear River. If any of you guys have specifics *please* let me know! I’m pretty eager to check out a new site. Thanks in advance!

    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 sp

    Pliosaur teeth? Moroccan

    Hi all, here are more pliosaur teeth questions from me.. these are from the Asfla Goulmima Morroco Cretaceouds turonien. I'm fairly certain the stubby one is pliosaur but seeing as I've been mistaken more than once, I'd like to ask here. I think the slender is plesiosaur, but again.. I'd like for people with more knowledge than me to pitch in

    Is Ichthyosaurus a Plesiosaur?

    Hello, I have a simple question but I can't find the answer and I think many of you probably know the answer. Is the taxon Ichthyosauria a part of the taxon Plesiosauria? I want to start learning more about Ichthyosauria and this fact simply bothers me not to know.

    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

    Weird Cretaceous vertebrates

    Hi everyone! Found these two specimens in the Upper Albian Burim formation in Ukraine. Would appreciate any help with ID! 1. So this 1.2 cm tooth is as basic as they get - no carinae, no enamel ornamentation (enamel is there by the way), circular cross section and this really weird apical twist. When I found it in the sieve I thought it was a Polycotylid plesiosaur, but lack of striations is not typical of plesiosaurs. Can't find a large fish without carinae either (Icthyodectids, Enchodontids, Protosphyraena, Pachyrhizodus and other pachycormids all have carinae), although enamel
  23. Attached are pictures of my collection of four isolated teeth from Travis County, Texas with limited identifications. I am not an expert on pliosaurs, plesiosaurs, or mosasaurs. I just know fairly accurately in which member of a specific formation I found these teeth. All of these were located in or near a shell hash layer associated with oyster fragments, Ptychodus, or other regular shark's teeth. (1) 10/2/2017 - Upper South Bosque - ~91 mya - first picture (as cleaned). (2) 6/15/2018 - Lower Bouldin Flags - ~95 Mya - first picture (as found), second p

    Marine reptile tooth

    I visit a shop in Athens, i seen this tooth in a box with common mosasaur teeth, and i bought it because don't look like a common mosasaur tooth. Platecarpus? Plesiosaur? Fish? The size is approx. 2 cm/0,8 inch.
  25. Hi everyone I came across this box of marine reptile teeth from: Age 200 million/Rhaetic bone bed. I don't have the measurements of the fossils unfortunately, but do anyone see plesiosaur and ichthyosaur teeth here? I'd love it if there's pliosaur but probably not..
