    Russian ichthyosaur tooth?

    Hey! I just bought a “ ichthyosaur tooth” from online. The teeth sold out really fast so i had to make a quick decision. It’s suppose to be from the Belgorod region. So my question you is, is this a ichthyosaur tooth?
  2. I wanted to very briefly share something really pretty awesome. Some folks here know that in addition to Fossils on Wheels, I also work for the Gateway Science Museum. It’s a small children’s science museum and our fall exhibit is going to be about fossils. We are part of CSU Chico and the Geology Department is using our facilities to do some preparation work on a few fossils for the exhibit. I took some pictures of one awesome specimen. The table in the center of the frame contains multiple pieces of a Shastasaurus. It is a remarkable and scientifically important specimen. It w
  3. Hi all! Those who follow my reports know I was planning another trip to Ulyanovsk in spring. Well, here is the report, in continuation of 1, 2 and 3. This time I was on the shore for 3 days. In short, the weather was fine, the ice abundant, the competition high and the finds scarce. The trip felt more like an extravagant outing than a productive fossil hunt

    Marine reptile tooth ID Lyme Regis

    Hi all, Bought this tooth online a while back. It was sold to me as "Ichthyosaurus platyodon" (which I understand to mean Temnodontosaurus platyodon) from Lyme Regis. Likely found by the seller themselves, as I know they occasionally collect fossils there. However, for the following reasons, I'm not sure about this attribution: Overall, the tooth doesn't look like your typical ichthyosaur tooth to me: It has more of an oval rather than round cross-section It's labolingually flattened Messial and distal carinae run the full length of the cr
  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. @paulgdls is it possible to best guesstimate the size of a Ophthalmosaurus icenicus from just one solitary anterior caudal vertebra. Height 10 cms Width 10.5 cms Length measured at the neural canal 3 cms

    Unidentified Jurassic marine reptile bone

    Hi all, I've had the below piece in my collection for a number of years now, having acquired it thinking it was a juvenile plesiosaur propodial. It comes from the Oxford Clay of Peterborough and is of Callovian Jurassic age. However, when recently doing some research towards answering another question on TFF, I realised that - even though there's some plastic deformation going on - it doesn't quite look like the juvenile plesiosaur propodial I have from the rhaetic at Aust, nor does it look like a plesiosaur propodial

    Whitby area reptile bones

    Daughter and I had a walk in the Whitby area this morning, didn’t come away with much but these two little chunks of bone made the trip worthwhile. The larger one (pics 3-6) appears to have ribs no more than about 5mm in diameter along with a lot of other bones. The smaller one (pics 1,2,7,8) looks to have two or three partial verts, but I can’t see if the centres are concave like ichthyosaur and to me they look too flat to be ples/croc. Can anyone shed any light on either piece? Thank you for looking
  9. I propose to buy this specimen if it is real. The seller told me that this specimen should belong to the pliosaur based on his experience, but I had a hard time to identify whether it is an ichthyosaur tooth or a pliosaur tooth. Is it an ichthyosaur tooth or a pliosaur tooth?

    Ichthyosaur from Yunnan

    This is an unprepped ichthyosaur from Luoping, Yunnnan Province of China. It measures 70cm in length. Any idea which species is that? And the completeness of the fossil?
  11. After a few conversations with forum members I thought it would be useful to share some Russian papers which have probably never been translated into English, thus are not known (at least in detail) internationally. I picked 5 of the best Russian-only articles I had found which are NOT limited to local aspects and descriptions (there are quite of few of this kind) but suit any person interested in marine reptiles and give some general knowledge on the subject. The authors are our most prominent specialists. Translation into English or any other language can be made with https://translate.googl
  12. Hi all! I was finally able to visit the Volga site thanks to a water level/ good weather window. The journey was mostly a success, I got a better understanding of the site, used new means of transportation and examined more of the shoreline. Among the finds were two dozens of marine reptile verts and bone fragments and LOTS of ammonites and other mollusks. Unfortunately the river level was not low enough, 1m higher than during my 1st trip, 0,5m lower than in the 2nd. But it was at least possible to walk the shore. There's still a lot more to do, but now I have a pretty clear idea how to m
  13. Hi, I'm considering this partial ichthyosaur jaw with 5 teeth (3 in a natural position and 2 others that have been displaced--one is on top and one is on the backside) from Jurassic (Tithonian) deposits in Tartarstan, Russia. The seller, who is also the finder/preparer, has identified this as Undorosaurus and noted that there is repair to the last tooth at the end, which broke and has been glued back together, and some holes that he filled in on that tooth--these are shown in the second photo with the red line (repaired break) and circles (filled in holes), as drawn by seller--but

    Ichthyosaur or pliosaur tooth?

    Hello all I acquired this tooth recently. It's those famous russian deposits that produce ichthyosaur and pliosaur remains. I bought it as an ichthyosaur tooth, but could it be it's pliosaur? I've noticed rootef ichthyosaur teeth have a bit different root, like a pronged root. But I'm hardly an expert so I'd greatly appreciate feedback from others
  15. I have just seen this for sale and while it could potentially be a nice addition to my daughter’s ichthyosaur collection, the attempted prep is a bit off putting. The seller says it’s on ‘calcite beef’. How difficult would it be to just tidy up those air scribe marks? I don’t see the need for any further exposure, just a bit of tidying. Do forum rules allow me to ask what the appropriate cost of getting this done professionally would be if I didn’t fancy attempting it? Thank you for looking
  16. Hi, I am interested in this. Sold here, seller says its ok to have a second pair of eyes look it over. From Holzmaden. Slab is 50cm. Jaw is 14cm. Seller thinks jaw has been added. My main concern is have the vertebra been added too? Thanks

    Whitby area Vertebra

    Braved the cold today to have a long walk around Runswick Bay and beyond. Best find was this vertebra, found in a slab of ammonites. Needs a little more prep to get the shale off. Any idea if it’s Ichthyosaur or something else?
  18. Hi all! Following the first topic I'll show you another fossil layer in that same location, Epivirgatites nikitini ammonite zone. It's the lowest of the three layers in Fili Park, relates to the middle Tithonian (Volgian, upper Jurassic) and is known for big ammonites and vertebrate remains. It's the last remaining accessible site in the region where you can count on finding Jurassic vertebrates. The finds are stable, but small, scarce and involve sifting.
  19. My 9 year old daughter’s collection had outgrown the old shelves so we took a trip to Ikea today to get something more suitable. Though I don’t think it’ll be long before this one is full too...

  20. New 'sea dragon' species discovered by amateur fossil hunter off English coast By Jack Guy, CNN, December 10, 2020 The open access paper is: Jacobs, M.L. and Martill, D.M., 2020. A new ophthalmosaurid ichthyosaur from the Upper Jurassic (Early Tithonian) Kimmeridge Clay of Dorset, UK, with implications for Late Jurassic ichthyosaur diversity. Plos one, 15(12), p.e0241700. Yours, Paul H.
  21. I visted Aust Cliff on the River Severn, Gloucestershire UK back in Feburary and managed to find a large block of the 'Rhaetic Bone Bed' . Lots of bone fragments, fish teeth, even a shark fin spine! But my best finds are a paddle bone and large tooth. (Still got plenty more rock pieces to break open and search for more, so a long term project...) However i would like to I.D this Ichthyosaur in particular. Does anyone know about the early ichthyosaurs from the late Triassic? Age: 208 - 201mya (Late Triassic: Rhaetian) - Aust Cliff Paddle bone - humerus?

    Unidentified bone

    I recently bought a bit of a job lot of things online just to get an ichthyosaur tooth for my daughter’s collection. Along with the tooth, an ichthyosaur bone and some acrodus teeth was this. The seller stated that it is from the Rhaetic bone bed in Somerset and is triassic. It looks a lot like the other ichthyosaur bone in the lot, but is anyone able to identify it? Thank you for looking
  23. Hello all- With a five day weekend and some pretty good weather (for late November), and the honey-dos done it was time for a day in the field. I went to a new part of a ranch that I have only been to several times. Previous finds include an ichthyosaur snout and two plesiosaur verts. The goal was Jurassic ichthyosaur bones. But this place has a series of fossiliferous horizons to explore. Other targets included articulated Jurassic crinoids, pterodactyl tracks, and small dinosaur bones. I say small bones because it was a mile and a half (2.5 km) walk to the bottom of the hill with
  24. Hey guys, I just posted a video where I find some huge verts from an Ichthyosaur (towards the end of the video) They're the biggest articulated backbones that i've found!
