  1. 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

  3. Could anyone PM me somewhere where I could purchase unprepared Green River fish? Thanks in advance
  4. 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.
  5. 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.
  6. 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?
  7. Fossil Fish of Madagascar

    Hello! Good night to everyone from my favorite forum! I would like to know, please, if this beautiful fossil fish of Madagascar is real, but I believe it is, and of what species it is. Does anyone know in which formation, or region of Madagascar in which it was discovered? I'm grateful for all the help! My friend please: @oilshale
  8. Hello my friends! Good Morning! I'd like to know, please, if this fish died doing, what I'm thinking he was doing ... Is it really a coprolite? The coprolite is his? I thank you for all the answers!

  10. Gone' Fishin

    Figured I'd share my current project here. I'm currently testing different sandblasting media and their effect on various matrices since this is a somewhat new application for us at Vaniman. The picture is an almost-finished Green River Fish that's roughly 4" x 2" in size. I will be doing a full-scale article regarding the entire process but wanted to share some of the work with you all for fun. I have a lot more pictures so if you're interested- let me know. It's only letting me upload one (?)

  14. This is another installment of the ongoing display project detailed in previous posts; http://www.thefossilforum.com/index.php?/topic/80671-display-stand-project-redux/ Here is the wooden base; sanded, shellac applied and drilled for the brass posts. I was having considerable difficulty with the shellac "gooping" up as I mopped it on this piece. I finally realized that I was down to about the last 20th of the batch I had mixed up. It had become significantly thicker than ideal via release of its volatile solvent. I cut the remainder with some more denatured alcohol and all was well. The wood is Yellowheart, Pau amarilla. It is a native of Brazil. Next the brass rods, formed to fit the fossil are tried in place. The sharpie mark visible on the right post was removed later. Here is the nodule containing the fossil fish seated to assess fit. The fish is from the Cretaceous of Brazil, Rhacolepis buccalis. Wax was applied to the wooden base and buffed to a low gloss. The finished display was then ensconced in its new home in the snolly great room.
  15. Moving away from Trilobites, I wanted to try my hand at a fish. This is my rendition of Priscacara serrata, a common species of the Miocene, in the Green River Formation. The fish looks like a Perch, or a Bass, because all three are in the Percinae Family. Priscacara is an extinct member.
  16. I've just visited this hill directly north of the Trump National Golf Course (yes, the president owned a golf course in my city ) which I was told by a museum docent had fossil fish scales. Here's what I found which could possibly be fish scale fossils, but I need a full confirmation on this. Some notes -All three rocks are associated- they were all part of a giant piece of shale rock which was broken into pieces when I found it. -The "fish scales" are a more darker or orange brown. -I think I was unable to capture the best possible detail due to the absence of natural lighting which made details more camouflaged. -Each "fish scale" lie on only one layer, throwing off the possibility of it being a crystal. -The black stuff are dendrites or a similar type. -Found in the Palos Verdes Hills, directly north of the Trump National Golf Course. Rock 1 Rock 2 Rock 3 Is this my first ever fossil find or another bust?
  17. Went to the Fossil Fest in Round Rock, and I came home with a kit to clean off a fossil fish. Though it'd be worth a try. The slab is from Wyoming, about 3" tall and 5" long, and they provided a tool that was really just a paintbrush with a steel nail attached to the other end. It's a bit beat up. Some of that was me and my inexperience, some of it was already like that. A lot of fin rays were already broken, and I'm pretty sure some of the fins were outright missing their tips even before I got into here. Maybe something nibbled on the edges a bit? I'm looking for some advice on how to do better, basically. Most of the skin came off, for one thing. There were especially loose flakes of matrix that looked like I could remove them with my fingertips, and whenever I touched one with the nail to take it off, it took the skin with it. I'm not sure if that was my fault or not. It also looks sort of like some of the skin was pulled towards the tail somehow. Damage or not, I think it worked out pretty well for my first try, at least it's mostly intact.
  18. Hi all, I saw this Diplomystus online for sale. I was surprised by the prize: 20$! But then I started to get a little suspicious. Though most fakes are mosasaurs and keichousaurs, I heard that fossil fish from the Green River formation are often re-painted so that they look more splendid. Though I am pretty sure that this specimen here was originally 100% real, I think that it might have been painted on. Is my suspicion right, or is this one 100% natural? Here is the info they gave: What do you think? Thanks, Max
  19. Here's a good question. I do have several big fossil fish from the Green River Formation and already have a good idea how to hang those big monsters, but what about the smaller fossil fishes on smaller slabs of rock that are not framed? There has to be a way? @FossilDudeCO Fish like these in the picture and a whole lot more. RB
  20. Hi, I just got back from Kemmerer with a large amount of fish fossils to prep and have an Aero scribe. I was wondering if a Micro Jack would be better as the vibration of the Aero knocks some of the scales off. If the answer is yes, which Micro Jack would be best in your opinion. If anyone has other prep suggestions I would also be interested. I've read all of the old posts that I could find on the subject.
  21. Jalama Beach

    I've heard of fossilized fish being found on Jalama Beach. Is there still lots of material being found there?
  22. Jaws & a tail

    I have found fish tails previously -- this one is smaller and in quality condition. WHich types of fish moght have a vertical tail like this one.. Salt water? Fresh Water. Approximate size L .8 x W 1.2 Inches Now the JAWS!!! H 1.0 x L 2.3 inches The teeth are 2-3 mm. I have not previously found anything like this.
  23. These have been a long time coming but they arrived just yesterday. These are fish concretions from Morocco. Ive never had any experience with these and have only seen about 3 fish from Morocco that are any good, so this is truly a gamble. But if you don't gamble, you cant win. Im going to go on the prep attack on one of these today and see what happens. im excited and nervous at the same time. Wish me luck. RB
