  1. Hello Fellow Fossiliers!! So whilst on a field trip with the OUGS in Lyme Regis the other day I stumbled upon this rock which has a bivalve and a partial (what would have been huge) ammonite in it. As you can see the ammonite has undergone mineral replacement and has crystallised, seen as its not really structural intact from the outside and seems to only be 1/16th of a complete fossil would this look good if I sliced it in half to open up the inside? And, if so, seen as I have no real prepping/cutting tools to speak of how would you recommend I go about it? I have asked a local mason to run it through their machines, they quoted £30 max depending on how hard the stone ends up being, I would prefer to do it myself and have the tools and ability to do it again should i need to. It stands roughly 18cm high on its end as picture. Thank you all in advance for your opinions and advice!
  2. Odd Ammonite

    Hi. I'm an ametuer fossil hunter from England and I'm new here. I was hoping someone could help explain to me what this extra growth is on the side of this ammonite? I found in Lyme Regis England which is part of the Jurassic Coast. I have found many ammonites which are better preserved than this one but I've never seen one with this strange extra section to its shell? I was also hoping that someone could identify the species for me. Any help you guys can provide will be gratefully accepted.
  3. Calcite ammonite prep

    I found this lovely calcite ammonite at Saltwick Bay along the Yorkshire coast of the UK a while back. There was no shell remaining from what I can tell, leaving just the calcite formed inside. Not sure if this is common at all?
  4. Ammonite ID

    So I recently purchased this ammonite off of the popular auction site for a good price, not something I usually do, but it looked nice and was already out onto a plinth. Unfortunately the seller doesn’t know where or when it was collected, and my knowledge only really expands along the yorkshirecoast in the U.K. I was wondering if anybody could help me with identification please. Thanks.
  5. It’s been a long time since I posted here. So here’s a thanks to everybody that’s helped me out in the past on here. It’s seriously appreciated. So. Here’s a lovely 6 inch Hildoceras I found recently at Kettleness, I’m the Yorkshire coast. She’s a beauty. A few of the outer whorl chambers are a little crush, but it just adds to the piece of think
  6. Fossil identification from Comox valley

    Hi folks, I found these two fragments on the Puntledge River in Courtenay, British Columbia, Canada. These are from shale rock of Upper Cretaceous age. I think the one on the right might be a heteromorph ammonite and but I have no idea on the left one. Perhaps a thick shell? The pieces are about 5cm in length in the photo. I would really appreciate any ideas on what type of fossils these are. Cheers, Martin
  7. when i look at goniatites and ammonites i see no diffrence. so what IS the diffrence between the two .
  8. I bought this ammonite many years ago, and I only know it is from Madagascar. I don't know anything else about the particular location within Madagascar or any layer it was found in, etc. So I realize it may not be possible to tell what type it is, but it would be fun to know, if possible. Hmmmm...the program won't let me upload for some reason...the images are 12 MB, 13 and 14. Does that mean I'll have to adjust them to a smaller size file in order to upload? I was trying to have good detail for identification.
  9. Squashed ammonite

    I found this squashed ammonite about a week ago at saltwick bay. It had washed up onto the beach, so could be from here or elsewhere. it’s squashed and not 3D sadly.
  10. Dear TFF members, I have a whole box of Jurassic ammonites that are perfect for those, who want to try their skills in preparation (or simply like preparing fossils ). The are more than 30 items in the lot - their sizes range from 3 cm to 11 cm.
  11. Ammonite fragments ID

    Hi everyone! Today I went hiking with my friend at 3000m+, The location I went hiking in is very near a place where I heard you can find ammonites and belemnites. I pulled this rock out of a boulder with many layers of slate in and found a partial piece of an ammonite. I was wondering if anyone out there can recognise the specie and the period? I found it in Switzerland, near a Glacier called « Plaine Morte » The first 2 pictures is the one I found and the second 2 is the one my friend gave to me (which he had found less than a km away from that location) Any help would be welcome Thanks so much! (Tell me if you need more pics)
  12. Hello everyone, I'm an Italian amateur collector with a small but nice collection of fossils and minerals that I started when I was 5yo in 1995. Then at 15yo I put apart my passion until few days ago when, using my 3D printer, I made some nice modular drawer to reorder in my collection of +-1000 pieces. I will finish the project in the next weeks and I will share it with you, as it can be of inspiration for your collection as well. Doing this hard work, I looked with a more mature point of view some big fossils that my parents and friends (not experts!) gave me as present many years ago. I already noticed that some are painted or assembled, but I would like to hear your opinion about them. #1 Let's start with a good one. This was a present from my mom, so I know she spent not few moneys to buy this fossil fish. I think that it 99% real. My only concern is the right side/section of the matrix that has a change in color (you can see it in the video). Maybe just a not-too-bad restoration... I drew circles around fishes with the pencil when I was a child... I should delete them! #2 Now a bad one... In this example I noticed that maybe the fish body is real (but low quality), it is mounted on a new matrix, and fins are painted... Am I right? #3 Another bad one... This ammonoidea seems painted. The matrix has some fossil shells, it is cracked and repaired (you can see the crack in the video, back side). I'm wondering if it is totally fake/sculpted or only painted. What do you think? #4 The last assembled fossil fish. This one is funny! Sedimentary layers are not parallel with the fossil... Overall I think that the body is real but bad preserved and with some painting. What do you think? #5 This was one of the first fossils of my collection. I personally bought it in Morocco in 1995. I think that this is a real one, joint is perfect. Agree with me? #6 Finally, the last piece: a cambropallas trilobite. About this one, I know that it was bought in a good shop and I think it is not too bad. I'm not sure about the matrix (see the back side), but the main body seems real. It, of course, has some restorations. I'm looking to hear from you. Final thoughts... I'm considering giving away false ones, in particular #2, #3 and #4. But it is also nice to have them to show how fossils are faked/retouched - I think they're part of the amateur paleontology history. I hope you appreciate the photos/videos I took to show some of my fossils. Thanks in advance and best regards!
  13. Smooth ammonite from Guizhou

    This ammonite is from Guanling, Guizhou. It’s special in that it is very smooth, while the surrounding small ammonites have ornamentation. Any idea which species is that or why it is so smooth? Thanks!
  14. This is a 23cm Phylloceras ammonite whose shelled has been removed to reveal the intricate suture pattern beneath. The stand is custom made out of steel(very heavy), then powder-coated with hammertone silver paint. Early Jurassic–Late Cretaceous Age range: 235.0 to 66.043 Ma Tulear in southern Madagascar

  16. Hey, all! I’m planning a trip to England’s Jurassic Coast next summer. I’ve researched areas like Dorset, Charmouth, and Lyme Regis. I plan to hit all these in my time there. Any other recommendations or information I should know? I’m excited to explore the area and collect some new fossils!
  17. Hi - first post on forum. I'll be travelling to South Dakota (Badlands & Black Hills) from Kansa City during the first 2 weeks of September. If anyone would have tips on collecting ammonites in the area, I'd appreciate the help. I've collected ammonites in Texas but never found a location in South Dakota. Thanks in advance - Tom
  18. 94mm Dactylioceras tenuicostatum prepared inside a geode. Tenuicostatum zone, Early/Lower Toarcian (183.0 - 182.0 Mya) Kettleness, North Yorkshire, UK I bought this from a well known collector named Anders Grube in Germany.
  19. Good time at the North Sulphur River in Ladonia, Texas this weekend. Here are some of the things we found! I’m curious about the gray ammonite (bottom right). I’ve attached a few photos at the end (first two photos) to see if any of you know what the black line is running through it at the bottom. It reminds me of the vein in a shrimp!
  20. Dear fellow forum goers, These past few weeks have been quite busy, but that has not stopped me from going on the occasional fossil excursion. A few trips went by since my last posting and I decided to let some trips accumulate before posting again. On these trips I interacted with forum members @Woopaul5 and @frankh8147. The most recent trip was today, 08/12/18, and was somewhat productive. Frank found what we believe to be a part of a mosasaur brain case, which will surely be in his "finds of the year list". I was not as luck but ended up scoring a small point fragment and a jaw section of some fish. There were also some nice quality teeth that I found today. Other than this trip, I scored some nice finds on a few other trips throughout the two months. I hope you enjoy the finds, as I enjoyed finding them, and have a nice day. Kind regards, Trevor Overall Finds Stream Worn Shark's Teeth
  21. Hi all, So a few weeks ago now I went to the location Carniol in France to look for fossils. And we found lots! Most of the finds are pyrite ammonites, but we shouldn’t leave out all the belemnites and little shell steinkerns we found. All the fossils are from the Aptian stage of the Early Cretaceous, and apart from the belemnites all have been replaced by pyrite. So I've already taken out all the belemnites and rinsed the clay off of each one (they’re looking gorgeous right now!), because their shells are not made of pyrite (and seem not to require any special treatment). By the way, does anyone know why only the belemnites are not replaced by pyrite, while all the other fossils are??? But now comes the question of all the pyrite fossils. All are very small. Some were found already starting to “rust” (I suppose this is due to pyrite disease?), but most are still in good state. Nearly all are still partially covered in dry clay though, and (just like it did with the belemnites) I suppose it will come off very easily as soon as it comes in contact with water. But, here is where I am a little worried: Rust is due to the oxidation (—> oxygen) of iron. And in water there is oxygen too, and more of it than in air. Therefore I’m scared that rinsing the pyrite fossils will accelerate the process of pyrite disease and make them “rust” more quickly. So what should I do to clean the fossils? Is it okay if I simply rinse them off? Or is that a no-go? Or maybe I should do it in a special manner or with specific substances? And, finally, what do you think is the best way for me to handle these fossils so that they “survive the pyrite disease” the longest possible? I know that there are a few ways with some weird chemicals to treat them, but I’m only a kid with limited equipment, money and experience, so I’m not able to do anything too intricate or acquire very funky chemicals. I’ve also read that apparently there are two different types of pyrite? How do I know which one my fossils are, and is there anything I should know more about it? Thanks in advance for your help to all those questions! Max
  22. South Texas Siphuncleage

    I found a couple ammonites this summer that needed very little prep. The first is a Pecan Gap fm Pachydiscus travisi, not remarkable for quality of preservation, but rather for presentation. With both impressions and the steinkern found eroded out together, I have “all the pages of the book”, something that doesn’t present often, in my experience.
  23. Amateur fossil finds

    Hey, I’ve finally spent some time on the Jurassic Coast the last few days around Portland, Lulworth Cove and Lyme Regis / Charmouth beach and thought I would share what I’ve found. Not loads but my own first fossil which I’m pretty proud of even if it’s tiny lol! It’s part of a infant ichthyosaur neck vertebrae if I’m correct. Also some photos of Ammonite imprints on some big rocks and a rock I found and broke open with an ammonite imprint and possible tooth imbedded in it? Also random photos of not sure what lol let me know please what you think.
  24. Mystery ammonite from Madagascar

    I recently purchased this chunky ammonite from a Chinese seller on eBay. The seller said it was from Madagascar but provided no other information, and I haven't found any photos of Madagascar ammonites that look like this. The suture patterns are unusual (to my untrained eye), and the body chamber looks broken off rather than cut. Total length is about 6cm; width across the body chamber is about 3cm. There are currently several others like it available on eBay (search for 'raw jade ammonite'), some with more pronounced ribbing. Thanks! I appreciate any ideas you have about this one.
  25. Hello! Here is the small preparation sequence of the Lower Cretaceous (Aptian) ammonites Nodosohoplites subplanatus Egoian, 1965 from the North Caucasus of Russia (Krasnodar region, bank of the river Hokodz).
