  1. An awesome tooth !

    Yesterday I was again in the quarry Kromer near Holzmaden (Lower Jurassic) and I found a really nice tooth ! The tooth is about 2 cm long and 1 cm wide ! I think its one of the biggest tooth I have ever found ! Its a Temnodontosaurus tooth, which is a large Ichthyosaur. In the "Schlacke" (a specific layer) you can sometimes find smaller teeth but such big teeth in a good condition are very rare. I am really happy about this one Especially because there wasnt much material there, so it was a lucky find ! The prep took about 4 hours. - The quarry, where I find this teeth will close during winter so the tooth is also a great completion of this year !
  2. What is this?

    I found this very small thing on my fossil of two ichthyosaur rib bones. It's very shiny. It is From Jurassic sediment (200 million years old) at Lavernock, South Wales, U.K. 5p coin for scale.
  3. My ichthyosaurus collection

    Here is my small ichthyosaur collection. I keep all my fossils in 19th century draws as it fits with our living room which is a Victorian cabinet of curiosities or Wunderkammer. Paddle basioccipital
  4. I have a question if Ichthyosaur is considered a reptile how come it gave birth to its young live? What separates it from mammals?
  5. Title says it all really. Can anybody help? @abyssunder @doushantuo @Fruitbat Thanks!

  7. Ichthyosaur tooth

    From the album Albian vertebrates of Ukraine

    Partial ichthyosaur tooth, supposedly Platypterygius (however now it is a wastebasket taxon)
  8. Ichthyosaur tooth

    From the album Holzmaden

    Another Ichthyosaur tooth from the lower Jurassic of Holzmaden / quarry Kromer. Its about 1.3 cm long and has a very nice root ! Some more pictures:
  9. Associated Ichthyosaur Bones

    From the album Holzmaden

    This picture shows associated Ichthysaur bones from the quarry Kromer near Holzmaden (Lower Jurassic). It was found by me last year and was prepped by Roger (@Ludwigia). The prep work took about 10 hours. The associated vertebrae are around 13 cm long and at the maximum the piece is 20 cm long. Beside those vertebrae there are also Ichthyosaur ribs and Ichthyosaur paddle bones on the stone. Maybe it was a small Stenopterygius or a young one from another species. The vertebrae: The vertebrae and the ribs: The paddle bones: Some more detailed pictures: This piece is the best one in my collection until now and the vertebrate find of August 2017 !

  11. Ichthyosaur vertebra

    From the album Holzmaden

    A 3 cm long well preserved Ichthyosaur vertebra from the lower Jurassic in Holzmaden. I found it last year and it was prepped by Roger (Ludwigia). The other side: And from another angle:
  12. I'd like to share my small Ichthyosaur collection. It includes Verts, ribs, a paddle bone and two teeth. These are from lots of different UK locations.
  13. Hi there. I recently purchased a big box full of shale, containing a number of disarticulated ichthyosaur bones from South Wales. Mostly ribs, but there's also a humerus and one or two other unidentified bones too. It's not an amazing piece, but I'd consider it good practice. I've been trying to work out how to prep it. It's in many pieces, and putting them together is a bit of a task in itself! As you can see from this terrible photo, I've made some progress. I've numbered the joins so that their positions can be found easily, and drawn in marker pen on the surface of the shale where the bones appear to run beneath. I'd appreciate any advice from anyone that's done this sort of thing before. This is how I intend on proceeding: 1. Complete the jigsaw - and hope it all fits together! 2. Prep each piece to expose the bones 3. Set the pieces onto some kind of backing - not sure what? 4. Tidy up the prep, and use epoxy clay to fill the cracks. If anyone has any suggestions, I'd be very grateful. I've never dealt with any icthyosaur material before.
  14. So I drew a paleo-reconstruction of a noteworthy but sparsely-known apex predator Temnodontosaurus eurycephalus, which was believed to be the top apex of the Early Jurassic until the rise of proto-pliosaurs like Rhomaelosaurus. Unlike its famous squid sucking sister T. platydon (metaphor, not literally), T. eurycephalus had a thick skull with deep jaws and large robust teeth suggesting a macropredatory diet and probably fed on other ichthyosaurs, plesiosaurs, and anything else that it could swallow (Also, growing lengths of over 30 feet, it probably could swallow everything other than another Temnodontosaurus) This is actually my first time finishing a paleo-reconstruction using only a pen tablet and photoshop (All my other drawings were either unfinished or done on paper). I used a Huion 1060PLUS drawing tablet and Photoshop CS6 to draw this. Took at least 3 hours to draw, and I heavily referenced the holotype skull to draw the head. Turned out pretty neat, but I don't know if I should color/shade this.
  15. Ichthyosaur tooth

    From the album Holzmaden

    A 1 cm long Ichthyosaur tooth from the lower Jurassic of Holzmaden (quarry Kromer). Another picture:
  16. Ichthyosaur Teeth?

    I purchased these as Ichthyosaur teeth but i wanted to post here to make sure that that's exactly what they are. All are from the Rhaetic period of the Upper Triassic. Age=210 Million Years. Origin=Gloucestershire UK. Preparation=Gently Cleaned.
  17. Ichthyosaur tooth

    From the album Holzmaden

  18. Ichthyosaur tooth

    A beautiful 1.3 cm long Ichthyosaur tooth from the lower Jurassic of Holzmaden (quarry Kromer). From another angle:
  19. This Ichthyosaur fossil has just arrived in the mail, i won it at auction. It comes from Whitby in the UK. There are no repairs. On the last photo attached on top of the Vert, is this a rib bone possibly?
  20. Ichthyosaur tooth

    From the album Holzmaden

    A small (about 1 cm long) but very nice Ichthyosaur tooth from the lower Jurassic of Holzmaden. It has a nice root ! Another picture:
  21. The bad weather gave me time to spend some time classifying. so i spent some time on my albian stuff. Everything has been self collected (surface collected) over the years. Everything is also small, so i chose the screws cases to store them. Everything can be seen on a dedicated galery on TFF : here or in higher resolution on my flickr : here 8 cases... So here we go Ammonites : (3 cases) then crustaceans (2 cases) : Other inverts (2 cases) : And last one : vertebrate remains I hope you enjoy it. that's all for now.
  22. Ichthyosaur tooth

    From the album Holzmaden

    A small but well preserved Ichthyosaur tooth from Holzmaden (lower Jurassic). The tooth is about 0,6 cm long. Because of the small size its not sure that its an Ichthyosaur tooth. It could be also a fish tooth. From another angle:
  23. Inspiration and advice please

    Hi master prep guys This has been a real challenge for me and I'm struggling. Any wisdom much appreciated. Potentially I've got a lovely ichthyosaur paddle here but it's driving me crazy. The matrix is so flaky I've had to put a stack of thin Paraloid on to stop the matrix disintegrating. I'm wondering if adding the Paraloid has stuck the matrix to the bone. The matrix is softer than the bone but is dangerously flakey without the Paraloid. I have a pen, pin vice and a hammer. The last tool is rapidly becoming an option! Should I selectively remove Paraloid-ed matrix? Other thoughts?

  25. Ichthyosaur vertebra

    From the album Holzmaden
