  1. Knightia eocaena - 18 inch layer.

    From the album Fossildude's Purchased/Gift Fossils

    Another bargain from our favorite auction site. I didn't have any fish from the 18 inch layer, and the price was right. It is also exceptionally preserved, with all fins present. Knightia eocaena Green River Formation, Eocene. Wyoming. Fish is 4 inches (10 cm) in length.

  3. hey does anyone have any good tips for prepping a fish nodule?
  4. Who can help ?

    Dear all, Let me briefly introduce myself; My name is Marc, living in the south of the Netherlands, i'm 52 (not yet a fossil), I'm a chemical engineer working 5 days a week.... I'm new to fossil collecting; I'm a mineral collector but I recently purchased a collection of minerals among which some fossils. Most of them where labeled, except a few. I've attached a fossil fish and I hope anybody can help me with the determination. The label said "Fossil Fish, Brazil". That's all…... The size is approximately 15" (40 cm). Google search didn't help me solving this question. Thank, Marc
  5. Santana formation fish

    Hello all Today this fish came in my mailbox together with a specimen of Rhacolepis buccalis. This fish does not seem to be of the same species, but the skull, fins and tail are in bad shape or even absent. Most of the 'skin' is gone, uncovering some of the bones beneath. I know this will make it hard to ID, but maybe one of the fish experts can help me out. It's from the Cretaceous Santana formation of Brazil and it's about 21 cm long. Thanks in advance.
  6. Fossil Fish ID Help

    The seller labels this as a diplomystus from green river but I don't think it is. The fins look wrong to me. What do you guys think?
  7. Fossil fish id

    I recently bought this fossil fish at a shop. I don't know where it comes from, how old it is, or what type of fish it is. The guy that worked at the shop told me it might have came from Brazil, but he wasn't sure. The fossil itself appears to be in a clay/sandstone-like concreation.
  8. Hello everyone, and happy holidays! I recieved this fossil fish (single fish split down the middle, so it's a mirror of itself). I'm looking to make a display case for it and I was looking for some help. I have a piece of plexiglass I want to use for the cover, and originally I was going to just build a wood case that holds the hinged box the fish is currently in, with a slot on top where the plexiglass could be slid in place. But now I'm not too sure, as I've seen some medal standoffs that can be used to hold up a piece of plexiglass over it, but then the sides would be open. I was hoping someone might have any suggestions. I'd like to keep the original box, but it's a real pain to open and close while keeping the halves in place. I definitely want to cover it because it's super fragile and I want to keep dust off of it. Thank you for your time, and any suggestions are more than welcome! Happy holidays! Ps. The box open measures 21 inches long by 14 5/8 inches wide and 1 inch tall. Regardless, it needs a solid wood base/platform to sit on so it can be picked up. Thanks again!
  9. Are there any papers/articles on Enchodus being in the Kem Kem formation? Also does anyone have any specimens they'd like to show off here because I read here that some people have specimens of it, and it just hasn't been described.
  10. I just acquired a GRF fish plate with a Knightia, two Diplomystus, and an interesting ventrally compressed (?) fish. Any help with identifying this fish would be greatly appreciated. Thanks in advance.
  11. Hello I'm a newbie fossil collector (and newly active member) who happens to several interesting fossils for a decent price from our favorite auctions sites 1st is are Knightia. The seller claims that they are not restored or enhanced 2nd set are 4 Spinosaurus teeth. The seller claims that cracks have been repaired, but no restoration or composition has been made (Pictures 2-9 of teeth in pairs) 3rd is a Lycoptera which the seller claims is not restored or enhanced 4th are plates of Elrathia Trilobites from Wheeler Formation 5th are Fossil Ferns from Llewellyn Formation 6th is a Hyracodon jaw fragment I would like to ask if the sellers' description of the items are accurate and/or if they are restored, enhanced or composites. Cheers!
  12. Advice on my green river fish

    I have recently bought a fossil fish prep kit,tried to do it and have done for 5 hours,however randomly a small piece falls off and Ive gone as slow as possible is there anything i could do to help?
  13. Chinese fossil fish nodules

    Went to my property the other day to pick up our camping trailer and couldn't help but go through a couple more boxes in my fossil shed. Found these in a tote with a bunch of Scotia Bluff material. Not sure why they were in that box but made for a nice surprize. Here's the thing, I can not remember the name of these fish, the formation or the age. Nothin. All I know is that I got them from a chinese dealer long ago in Tucson. Any help is appreciated. thank you and I got more in the garage. RB
  14. Well,, it was just a couple of weeks ago when I was out on a fishing trip to the Green River Formation. We were invited back to the almost unknown 'Phareodus' layers!!! Very tuff layers for sure. We had to use special chisles for these layers along with the normal thin shims used for the 18 inch layers. We didnt end up with very many Phare's, only 2 but the boys did get some purty good B-Grade Phare's!!! What we did find was quite a few small diplo's and small Mio's in some very very nice high quality preservation. The one thing was,,, just how many small good preservation Mio's does one see? These are almost rare. What struck me also was the difference in the layers here! From one layer to the next can be completely different! Some of it was super nasty rock and had travertine on it. You find a fish in this travertine you simply toss it aside. That hurt! When the sun went away we had to go dig the 'mini' layers. The mini layers are very much like the split fish layers but you can get some really good hard layers there and you can also find some big fish there too along with the 1000's of little Knightia's. But the sun came back and again we dug the Phare layer. The boys also did some night fishing with lights in the famous 18 inch layers but only lasted about 3 hours. Still, some nice little prisci's for their efforts. It was also very cold! First morning was 32 dgrees. Tons of wind too and the second day destroyed out tent!!!!! Im gettin old and can do without the cold and wind, but for those of who know, after almost 14 months with this stroke I was for the first time able to actually do some work and for some hours. Quite happy to say the least about that!!! and even though I payed for that the next day, for me, it was Fantastic. And today, just one day after getting back I was able to unload almost all the fish, get them squared up with a square and pencil and now having a very deserved whisky and writing this! Wooooooooop Woooooooop!!!! I will pay for this tomorrow but I dont care. Ive always love getting out and fossil hunting and camping and its now finally gettting a tad bit easier. Here is my little set up before it got desroyed the next day!!! Here is a large Phareodus with some of the head missing from the 'mini' layers. The very first rock my middle son lifted. This fish is upside down. Had to build a wind block so we could have a fire for cooking baked taters with onion garlic and a slice of bacon. Makes for one heck of a baked tater!!! and some New Yorks too!!! The boys working the famous 18 inch layer. You can see in the lower left of this photo the small pad of the unknown Phareodus layer. Here is a small but very high quality Mioplosis from one of the 'Phareodus' layers! Im super excited to get these!!! To say the least!!! This fish, Diplomystus is one of the most awesome ive seen. Just fatter than a pig!!! Sad to have the tail end missing!!! This fish came from the 'mini' layers. If this had a tail I would have paid some serious moneys for it!!! Just check out the anal fin!!!
  15. I am wondering why Lake Gosiute has been closed off to the public. It is the only part of fossil lake that has catfish and I really want to try and find one, instead of paying thousands of dollars for one. I have heard it was bought by a company, but I was still wondering if they would let a small private team dig or if they would sell any of the fossils. Thanks for any help!
  16. Fossil Fish ID

    I recently bought this fossilized fish online. I was wondering if anyone could identify the species and perhaps pinpoint the locality/formation. Thanks, Seann

  18. I would appreciate some help/advice as I know very little about this stuff (although this forum is proving very interesting and informative). I’m looking at giving the fossil fish pictured below to a friend as a birthday present. It has been listed as “Knightia alta from the Eocene age, Green River Limestone deposits Wyoming” and is mounted on a presentation slab. The item is from an apparently well known UK supplier and comes with a ‘certificate of authenticity’. Does this appear to be genuine and is it a decent sample? There is what seems to be a squarish tool mark at the top centre which I’m guessing is from when the stone was split, and is perhaps a bit of a shame on what otherwise (to the ignorant at least) is a fairly pleasing looking piece.
  19. I was just going through a box of fossils that been sittin here in my office for awhile now. Besides lots of other cool stuff I ran into this little beauty. Diplomystus poweri from Hajoula lebanon and Cretaceous in age. I bought this about 20 years ago. I think its real? I only have my readers on at the moment and parts of the head look a bit fishy? No pun intended. RB
  20. Ive been wanting to get some fish done for a few years now. I have about 5 days of good weather left so since I got the abrasive unit up and running I started on this one. Its a Serrata from the Green River Formation and is in some real nasty rock. Its slow going and I figured I would use 50/50 bicarb/dolomite and cut back on the dolomite when I got to the 'thinner' things. Ha!!! I still had some of the 50/50 when I got to the gut and some of scale covered areas both above and below the spine and low and behold, it worked for those areas too!!! This really tuff hard rock makes for some really hard bones and such!!! I,,,,,,,,, am a happy camper. I still have a few hours left to finish this up, but its turning out purty dang good. RB

  22. Could anyone PM me somewhere where I could purchase unprepared Green River fish? Thanks in advance
  23. At a site where I have been finding heteromorphs, I have recently come across some vertebrate material. So far I have only found three vertebrate specimens; one bone fragment and two fish scales. I am hoping to get some information on their affinities. I am most interested in the fish scales, since it seems they would be the most easily identified. The site is in North Texas, the Austin Chalk group, Atco formation, upper Coniacian stage. For biostratigraphic reference, at this same site I have also found the ammonites Protexanites planatus, Phlycticrioceras trinodosum, Tridenticeras peramplum, Scaphites semicostatus, and Glyptoxoceras sp., among others. The bone (Figs 1-17) was found on Saturday the 14th of July. It is a small fragment from a more marly layer than the fish scales and most of the rare ammonites that I am finding are from, but still from the same site. The main part of it has 39 mm exposed length wise as shown in Figs 11-12 (some of it is still buried in the rock), and has a branch coming from the main part that is 22 mm long that forms a depressed canal structure in the rock (Fig. 14). The maximum thickness of the specimen that I can see is about 2 ½ mm. The branch begins to curve around when it meets the main part of the bone. The other end of the rock and the underside don't show much exposure of the bone except for a few bits poking through (Figs 16-17). I don’t know if the specimen came from a fish or some other vertebrate, but I would guess fish. If anyone can give more information on what kind of animal this came from and where this might have been located in the animal’s skeleton, that would be much appreciated. But I also know that due to its very fragmentary nature, a more definite identification may not be possible. The two fish scales (Figs 18-20) were both found on Friday the 27th of July over 100 yards from where the bone was found. These specimens are from a more chalky matrix than the bone, the same matrix that the rare ammonites are in. The first specimen (Figs 18-19) was found breaking open a large chunk of chalk. It is basically flawless and in excellent condition, and only has a little bit of obscuring matrix on the right side that could be prepped off. In the same chunk of rock that I cracked open to find this I also found a T. peramplum specimen. The fish scale is 5 ½ mm long by 5 ½ mm wide. The second fish scale I found (Fig. 20) was found within a few feet of the first one, possibly from the same fish specimen. It is a bit beat up and less complete than the first scale, but is larger from what I can see. It is 7 mm wide including the flatended area upon which the scale once was before it flaked away during excavation. The front part of it is still buried in the rock but could hopefully be prepped out. It is also in a chalky chunk of rock, not marly. I have noticed that these are less shiny than scales preserved in shales, though they still do glimmer a bit in direct light. They are also differently colored than most fish scales preserved in shales, with mine being on the red/brown spectrum while those in shale are usually black or dark gray. I am hoping that the distinctive symmetrical 7 way splitting shown on the first fish scale could narrow down the identification. I know that getting to the species or genus level could be very difficult, but could a family or order be at least possible? I have heard that identifying fish scales is challenging, but this paper indicates that it is not impossible. @oilshale, you’re a fishy guy (in a good way of course). Any ideas? Fig. 1.
  24. Dipity-Do Done

    Just finished prepping this great Diplomystus found by a guest at our quarry. It was the first fossil they have ever found so I wanted it to be something special for them. Not much to work with but it turned out pretty good. I used a scribe to clean up the fish a bit, PVA to stabilize the fossil and prevent further flaking, and then had to do some restoration using fossil putty and a bit of touch up paint to restore a few missing areas for them, as they wanted a piece that they could hang on their wall and display.
  25. sooo.... i found this on the "auction site" as you peeps llike to call it. and i would LOVE to buy it. buuuuttt is it real? also how do i post pics?
