  1. Hey there! I am relatively new to fossil collecting and hope to go on to do some hunting etc, but anyways! I am considering purchasing this keichousaurus hui attached and wondered if it is a real or a fake? As I know you need to be extremely careful when buying one of these due to the hight amount of fakes being produced. Thanks!
  2. Hi everybody, I have been looking everywhere for a decent keichousaurus fossil for the past few months, but everything on that popular bidding site seems low quality. I came across this one and was wondering if it is legit. Thank you in advance!
  3. Hello all, I started collecting fossils as a hobby a few years ago, trusting sources without question. I recently bought my first expensive fossil (Keichousaurus) online. I know they are often faked (or at least heavily restored) so I want to confirm that mine is legitimate. I did a scrape test which revealed more bone so that was good. However, I did an acetone test on a couple of the bones and the bones faded a little bit and the q tip I used picked up some dark grey/black. I also tried it on the matrix in three places which pulled up even more black on the q tip (more than the fossil had done). I was wondering if this is normal or not. Can you please help me determine if my Kiechousaurus is genuine? The picture shows one arm untouched (the top of the picture) which you can see is a bit darker than the bottom arm which has been swiped with acetone. Thanks for your help!
  4. Hi all. Is this Keichousaurus real or fake? This product is very cost-effective,but I have to admit there are dubious areas like the head and too-perfect tail I just want a confirmation form the experts Thanks My English isn't very good, please don't mind
  5. Hello fellow humans so, my friend has asked me to try to identify her late husbands collection and i am trying to do my research online about identification, and forgeries etc.. As he had a huge collection of books, taxidermy insects and these fossils, i am hoping that he would have purchased with scrutiny.. but who knows.. anyhow, im trying to identify these.. im not so aware of the different types of tribolites and if any are more rare than others.. also with the keichousaurus if tis real or not.. it seems to me like the digits may have been highlighted with paint, or maybe i have a bad eye, but i know thats a sign of forgery... but have also seen repots of genuine that have been touched up so to speak.... i haven't cleaned, scratched or changed anything since i got them.. i understand that it may be a lot of effort to help me out, besides being someones passion i have created a google photo album of all of the photos https://photos.app.goo.gl/yTbjFyGpTmr8BNix6 many thanks Daithi Dublin, Ireland
  6. Hi! I recently purchased the following Keichousaurus Hui. Although I have a modest fossil collection primarily consisting of Trilobites, this is my first Keichousaurus fossil. I had a chance to inspect the fossil first hand in the store before purchasing and while it looks quite nice to me, I would appreciate feedback from this group. IMHO, the piece is very attractive and presentable as a display piece (and it carried a correspondingly 'display piece' price!). I don't have any major concerns other than maybe the piece is too nice as it is nearly symmetrical, the detail is very fine, etc. Here is what I have observed: 1) The fossil is extremely 3D with well defined relief. Bones are thick, heavy, dark and well articulated. The fingers and toes in particular are very well defined. 2) The neck loop is very unique and the 'physical loop looks right' in that the bones go under and around each other in a believable way. 3) I did a very light acetone test on most bones, including the fingers and there was a bit of soil that came up. I did not see evidence of ink, nor did any of the bone detail wipe off. 4) The head is very detailed with needle like bones that might be teeth? 5) The matrix is soft and from the side is clearly layered. The back side of the matrix is flaking off and has a section that appears a little glossy... perhaps epoxy of some kind was used to shore up a weak back side? 6) There are thin cracks/striations that cross the specimen. These line up with the natural lines of the animal, so it does not appear that it is a composite. 7) There are no bubbles that I can see. 8) There appear to be a jumbled lump of bones in the gut... maybe the little guy's last meal? I have a ten day purchase guarantee from the seller and would love to keep this piece for display. Would appreciate the experts in this forum to help give me some confidence as to the quality of this piece, thank you! Jason
  7. Hello all! I just wanted to share a Keichousaurus I got in the mail today. It was an Easter gift to myself. It is an acid prepped specimen. I was a little worried about it but it looks excellent! The only noticeable paint is on the calcite line connecting the neck vertebrae together, which I have no problems with. Otherwise it looks complete, with all of its toes intact, and I wanted to share, because I am excited about it. I included pictures. There are a few tiny teeth in its mouth, but they didn't show up on camera. If you see anything off with it that I haven't noticed, please let me know. Thank you all!
  8. I was shown the photo of a juvenile Keichousaurus from the type locality in Guizhou this morning and was asked to check its authenticity. It looks real at a glance but when I look closer, it looks suspicious. I was told that this is a man-made one. Take a look.
  9. Hello all. I just wanted to share some information about keichousaurus that I found very interesting. Crazyhen recently identified a keich specimen I have as a male. I wondered how he knew that, and did some research. As most of you probably already know, keichousaurus hui was sexually dimorphic! Males can be told apart from females by the proportions and length of the femur and humerus. Males are also often times larger. I included a diagram telling apart the male from the female. A is the female, and B is the male. Thank you all for reading, I enjoyed learning this and hope some of you do as well! https://www.tandfonline.com/doi/abs/10.1671/039.029.0230 https://royalsocietypublishing.org/doi/full/10.1098/rspb.2015.1658
  10. Keichousaurus with Jellyfish?

    On this plate is a Keichousaurus and an unknown fossil. You can see there is something at the left hand corner, does it look like a jellyfish?
  11. This is a real specimen of Keichousaurus but I don’t understand why it’s pelvic girdle is shaped like this. Any idea?
  12. Hello everyone, I purchased a Keichousaurus from our favorite auction site. It was a reputable seller and using a black light and closer inspection it's real. Plus I have the added bonus of it having been dropped and split through as it was only packed with newspaper and not market fragile, then played footy with by australia postal service... so, yeh.. its' real but it's broken. The top left has crumbled and is discolored. and it has a crack through the tail. Can anyone advise me how to adequately repair this? I have been promised a replacement specimen which will be sent soon, But I would like to salvage what I can. Thanks in advance.
  13. my collection

    Some of my favorite fossils. I start with my new nearly 30cm big keichousarus.
  14. Baby Keichousaurus

    Hi Folks, I wanted to show you a baby Keichousaurus I got for a song at an auction site. It is super tiny and I really like it. It looks pretty unprepped and is raised off the matrix by maybe a 64th of an inch. The matrix measures 2" x 2 3/4" and from nose to tail it is 2 9/16th". Hope you like it. Photos taken with Nikon D3300 with 85mm macro lens
  15. I'm looking at purchasing another Keichousaurus for preparation, and wondering what the experts' opinions are on which of these two would be easier to prep for a relative beginner like me. The first one looks entirely covered in shale, and the second seems to be a little more exposed. I have my Paasche air eraser that I was planning on using, although if someone recommends an acetic acid prep over the air abrasive for these specimens for one reason or another, I would love to hear suggestions. If the second one is more likely to be incomplete/damaged than the one under rock, I would prefer to stay away from that. But that being said, if it would truly be easier to work with the one that is already partially exposed, I am all for that!
  16. I got a soft slab of very nice Keichousaurus a a year ago. I keep it in a drawer at home, perhaps it’s too humid, I found that it’s broken into several pieces. Could anyone advise me how I could keep the soft slab without breaking? Shall I apply a layer of protective solution on the slab?
  17. Hello. I see this photo and dont understand - this is poor quality or not prepared Keichousaurus. I did not get answer seller
  18. Hi all, I recently purchased this Keichousaurus specimen off an online seller (not online) and wondered if it was genuine or not... the seller stated that there had been repair to the matrix (don’t know if that shows up in the attached images:|) The seller also said there was no repairs, painting, carving etc and that the actual fossil was 100% genuine. Inspecting it with a loupe I could see the bone matter is raised from the matrix (slightly) and that there may be teeth present on the skull, but I don’t know if they’re painted on, as that is sometimes the case. Anyway I thought I’d come here to get it checked out as I’m not very experienced with fossils and fakes yet. Any opinions would be greatly appreciated Jai.
  19. Hi all, I've been searching the internet pretty thoroughly the last few weeks, checking everywhere multiple times a day to find a low-quality keichousaurus to practice prepping on, (knowing that 95% of specimens are fabricated or heavily restored) and I think I may have found one. The price is so reasonable that I really don't care whether or not it's partially fake or restored, as it will make a decent display or even a gift if it turns out to be 100% fabricated. So I suppose I'm wondering how much of this specimen looks fabricated, and if it would even be possible to attempt an air abrasive or acid prep for this guy? How rare is it to fabricate or even partially restore a keichousaurus that's still mostly covered in shale?
  20. Just ordred a kind of "cheap" and not so well prepped and maybe enhanced keichousaurus. Would be nice to get some opinions about the condition of this fossil. I know I should ask before buying but the financial damage isnt that bad and I`m quite cuurious about this fossil. Will be pretty interesting to compare it with my other keichosaurus, which was my first ever fossile and a few times more expensive beeing from triassica.
  21. Hello. Matured before buying his first reptile. Looked at the sellers - all from China. Attracts affordability, and not the best quality still suggests that I will get a real fossil. One seller has two reptiles of about the same quality. Forum opinion are they real? The second is how is the delivery from China - Hong Kong?
