    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

    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
  3. Hi everyone, found this in a new jersey cretaceous creek. Looks like a partial enamel something but I'm not exactly sure what it can possibly be from, it interestingly has some very defined ridges on the least worn side. Very hard to catch the clearest pics to show the sharpest definition but I tried to get the best I could. Maybe this can be a clue to a potential id. Pictures of it with whiteish background are upside down.

    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.

    UK Marine Reptile Teeth

    Hello all, I've had two teeth in my collection for many years now. I've recently moved and lost the supplied ID labels that came with them. I've taken this as a nice opportunity to see what others may think they are. I believe if memory serves me right the large tooth (Tooth A in photos) was labeled as a Simolestes. Then the smaller tooth tip (Tooth B in photos) labeled as Liopleurodon. I know both were found in the Wicklesham pit in Faringdon, Oxfordshire, UK. Upon some research, I found an article from 2014 with a Dakosaurus tooth discovered to be the largest in the UK at the ti

    Unidentified Triassic reptile bone

    Hi everyone, I recently acquired the below fossil, taking a chance as to what it might be. It came labelled as Mixosaurus sp. from the Keuper (Upper Triassic) of Kirchberg an der Jagst, but I can't place the bone... Initially, I thought it could be a broken mixosaur coracoid, though the shape doesn't match at all. In the below image the break is circled in blue, with the red circle marking a projection from the bone that I would not expect to be present if the bone were indeed a (mixosaur) coracoid, as shown in the drawing next to it (from Jiang, Schmitz, Hao and
  8. Hey everyone, I recently acquired this ichthyosaur vertebra that was originally collected in Penarth, south Wales, UK. What initially struck me was the vertebra's size, since it's by far the biggest one I have of any ichthyosaur: Now, other large ichthyosaur remains have been described from the very same location. The paper is freely available here: https://bioone.org/journals/acta-palaeontologica-polonica/volume-60/issue-4/app.00062.2014/A-Mysterious-Giant-Ichthyosaur-from-the-Lowermost-Jurassic-of-Wales/10.4202/app.00062.2014.full The cliffs at Penarth apparently conta

    Large NJ Cretaceous Bone

    Found this thick bone piece in a new jersey cretaceous creek and wonder if its possible to maybe id since one side has a distinct rough texture while the other is flatter and striated, I would guess either large turtle, mosasaur, or dinosaur. My friend joked its a theropod maxilary skull fragment, but we all know around here that material seems close to impossible to come across haha. Interested to hear any other thoughts.

    Utah septarian surprise

    In May of 2020, my boyfriend David and I drove up to Utah to go look for septarian nodules. I should preface this by saying that David has the most amazing "beginner's luck" of anyone I have ever known. Not only did we find a beautiful "normal" septarian nodule, David found a spot where apparently a large marine reptile of some sort died, and was later encased in septarian. We have since learned that this is basically the find of a lifetime! The beauty of these specimens never fails to amaze me. The large free form was cut and polished for us by Joe's Rock Shop. The matched pair was cut at Joe

    Ichthyosaur paddle digit (Wimereux): hit or miss

    Hi all, Found this stone at Pointe aux Oies in Wimereux two days ago, amongst the pebbles collected next to a shelve down towards sea from the spot where I had found an ichthyosaur vertebra (on matrix) two days before this find. I picked it up because 1) the stone is unusually flat; 2) has exactly the right shape and thickness to it for an ophthalmosaurid ichthyosaur paddle bone (see picture below); 3) has certain ornamentation top and bottom; 4) seems to be of a different type of stone than I've generally come across in the area; and 5) has some weight to it. It vaguely reminds me

    First egg from Antarctica

    https://phys.org/news/2020-06-egg-antarctica-big-extinct-sea.html I thought this was pretty cool (no pun intended).
  14. Hello again everyone! This is a specimen that was advertised as a Hydrosaurus Lingyuanensis. The specimen appears to have had some serious restorative attempts done at from the centre to the lower body. I wanted to ask if you could please let me know what you think regarding the authenticity of the specimen - particularly the areas that haven't been modified. The first image acts as a refernece, showing the approximate area where the photos have been taken. Thank you in advance. Frontal image + reference Back of specimen

    A 13 cm long stone with three nothosaur vertebrae and another unidentified small bone piece from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). The verts are very small, especially the one beside the bone fragment. The bigger ones are about 2 cm long. Detailed pictures:

    Sauropterygia bones

    From the album: Triassic vertebrate fossils

    A 20 cm long stone with a couple of bones from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). On the plate are two vertebrae, one rib and two unidentified bones. The quality of the bones is partly not good (especially the vert in the middle is bad preserved). The prep was not too difficult but it took quite a long time to finish it. Some more pictures:
  19. Hi, In 2013 I bought a keichosaurus fossil from online , and since then I haven't thought much of it, after me and my mum and dad moved to a new apartment the fossil got somewhat forgotten, but today I tried inspecting it. I read some of the treads here but even with this I can't decide if mine is a real or a fake one. From what I have gathered there aren't many outright fakes, but more so real ones that are enhanced. I will be glad to hear your opinion on the pictures (sorry for the poor quality but I had to use my phone). Any response will be very much appreciated. Bes
  20. Hi all, I was recently offered this tooth from late Cretaceous of Orensburg, Russia. Most likely Gaisky City District. I can't figure out if it's a Polycotylid plesiosaur or Pterosaur tooth. The overall shape is closer to pterosaur than plesiosaur. However, I am not aware of pterosaur having wrinkling like that, nor do I know of pterosaur teeth being found there. What are your thoughts on this? Thank you.

  22. The quarry Kromer near Holzmaden did open two weeks ago (it was closed during winter). So last Saturday I was there the first time this year and I have to say that I am kinda satisfied with my finds! I found several marine reptile teeth, some mainly incomplete bones and a fish with much potential. In this topic I want to show how I prep/prepped a plate on which originally two Ichthyosaur verts were visible. The verts are all about 4 cm big. Here is a picture of the unprepped plate: (I have the other parts...) The prep work is very difficult because the stone is extre

    Ichthyosaur paddle bones

    From the album: Holzmaden

    These are four Ichthyosaur paddle bones from the lower Jurassic from the quarry Kromer near Holzmaden. The prep was very difficult because the stone was kinda hard. I gave it up several times but now its finally finished. I hitted the bones a few times so its not the nicest piece. Maybe I will try to prep it from the other side one day. Some more pictures:
