    Found in Whitby

    Hi I found this on the coast of Whitby.. the circle at the top stud out and something different to the slate. After a bit of chipping the main bit came away easily and is definitely separate to the slate?? Any help would be greatly appreciated..
  2. @paulgdls I found a small piece of plesiosaur coracoid from the Upper Jurassic Kimmeridge Clay, Rasenia cymodoce zone. Do you know what species of plesiosaur it might have came from.
  3. Hi, Saw this for sale, was thinking of purchasing it, but wanted to confirm if this is indeed Plesiosaur. it is quite large for a partial paddle at 14 inches in length and from the Goulmima region in Morocco. Thanks.
  4. 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
  5. ... and it is only the beginning of January. A bucket list item I have been hunting for for a while. Plesiosaur vertebra from the Eagle Ford of North Texas.
  6. 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

    Oxford Clay Plesiosaur Tooth

    Hey everyone! I recently got a few marine reptile teeth from various formations in the UK, including this partial plesiosaur tooth from the Oxford Clay. The enamel is only partially preserved, but appears unworn and allows for a good look at the enamel ridges of this section. The curved, rather robust shape of the tooth and the irregular distribution of the pretty prominent enamel ridges made me move away from ichthyosaur or machimosaurid as an ID, and seemed more in line with the many plesiosaurs from this formation. But that's where it got more tricky.

    Plesiosaur tooth

    From the album: Holzmaden

    My first Plesiosaur tooth with a length of 1 cm from the quarry Kromer in Holzmaden, Lower Jurassic.
  9. Hello, this is my first post on the forum so firstly I apologise if I have done anything wrong. I brought these teeth a number of years ago and have only just got round to sorting them out. The first one was listed as Jurassic crocodile tooth and the second as Jurassic Plesiosaur tooth, they both come from the Oxford clay around Peterborough. I would really like to put a species name to these teeth if possible so any help would be greatly appreciated. My initial thoughts were Metriorhynchus for the crocodile tooth and Cryptoclidus for the Plesiosaur but I am a complete amateur and would love s

    A Trip to the Rhaetic

    Picked this big chunk of fresh rhaetic bone bed up today. It was twice the size when I found it but I was a butter fingers and dropped it accidentally and the other half disintegrated. Doh. Its a nice early Christmas present. If you look carefully, there’s a whopper of a plesiosaur vert in there. I’ll post some more pictures when I start digging into it.

    A plesiosaur tooth from Morocco ...

    ... But I don’t know the genus. It is from the upper Cretaceous, found in phosphate deposits from the Oulad Abdoun basin, Morocco. It is around 6cm in length.

    Possible bone from Ramanessin brook?

    I went to the Ramanessin brook a few months ago for the first time, while I was busy looking at my cretaceous shark teeth I completely forgot about this thing I found. To me it looks just like a bone but I have never found any type of bone in New Jersey before, I'm curious if it is one. And if it is, is it possible to identify what this could possibly be from.

    New plesiosaur species?

    Hi all. I recently acquired a plesiosaur tooth from morocco, khourigba, phosphate deposits. In a facebook group i was told the tooth is thicker than any known teeth from the area. Have the attentive reader here seen any teeth of this thickness? The tooth is about 2 inches long.

    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
  15. 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

    Plesiosaur Bones?

    I suspect this to be mosasaur. Can anyone confirm and more accurately identify?
  17. Another unknown piece, but at least with some information on its locale - Lavernock, Wales, UK. I believe it to be either Ichthyosaur or Plesiosaur but I'm afraid I don't currently have an idea what it is. I'd appreciate any input. Thank you, John

    Seatown U.K vertebra I.D

    Hello, as part of a great hunt at Seatown on the jurassic coast I found this vertebra covered in pyrite, my first thought is plesiosaur due to the size of it. However the upper surface looks unusual to other plesiosaur verts Ive seen, any thoughts?
  19. Hello. This is sold as Kimmeridge Clay Plesiosaur propodial with predation marks. It matches photos of propodials, but I am wondering if they actually are predation marks? Seller says the marks are probably pliosaur. It's been sold along with a bunch of other plesiosaur fossils that were dredged together. If anyone can help, that would be great.
  20. Hello all! I haven't done a trip report for a long time so I figured this would be a good time! I went to one for my favorite New Jersey Cretaceous streams on Friday and put in a few miles of walking. It was raining slightly but with hot it's been lately, that was actually appreciated! At the end of a mostly unproductive trip, I decided I was done and would turn around About a minute later, I saw something in the water and picked it up - it ended up being a nearly two-inch long, rooted Plesiosaur tooth!! I couldn't believe it; I've never found a Plesi tooth here this b
  21. It was initially being sold as plesiosaur when I inquired about it, but seller says it was mislabelled and is pliosaur--which, if accurate, even better! But I am dubious over Pliosaur ID because I don't think I've ever seen any Morocco pliosaur fossils up for sale. But, if anyone can take a look and let me if A) It looks legit and B ) Whether you think Pliosaur or plesiosaur is accurate, that would be great. 80 million years old, from Morocco. 17 inches along the straight edge and 10 inches along the bottom. Thanks for any help!
  22. Hello, new to posting on the forum and fairly new to fossil hunting. Found these very nice marine reptile vertabrae near Osmington Mills, Dorset. All found close together washed out of the Kimmeridgian Clay I think... Age: Oxfordian/Kimmeridgian? 163 - 152mya (both rock types there but I believe the clay cliffs above the beach are Kimmeridgian. Can anyone confirm I have 2 different types (Plesiosaur & Ichthyosaur)? Also any guesses at what species they are likely to be or is it not possible to narrow down from a more generic Ichthyosaurus sp./ Plesiosaurus sp. ?

    Cimoliasaurus magnus

  24. Hi all My son and I were looking through some teeth from the NSR and want to get your opinions on this one. We first thought that this was a mosasaur tooth; however, someone suggested that it may be a plesiosaur/elasmosaurid tooth. We wanted to gather some more opinions since we have no idea what it is. The tooth measures 16 x 6 x 6 mm. Thanks and Happy New Year!

    Help w/ ID new fossil finds!

    Hello! I'm a pretty novice fossil hunter, so I look for things that stand out! Recently I found these in a span of about two weeks, I haven't seen anything like them before. The small ones all have a flat/facet on the posterior side, same teardrop shape, and the larger ones look like " big ears" to me, lol. I thought maybe iron concecretions at first, but the small ones look different, in that they are not "round". Ammonites? Reminds me of some of the pics posted of plesiosaur fossils, I have more pics, but the files are too big to post all at one time - I would really appreciate
