  2. Could someone assist in determining if these two items are an Enchodus or Xiphactinus? I found the larger one this past Saturday and the smaller one a few weeks ago, same general area at GreensMill Run in Greenville NC. Found these among whale bone, great white, tiger and crow shark teeth and a couple sharks of likely mastadon tooth - obviously a nice mix from a huge time span. I assumed enchodus until a friend mentioned the Xiphactinus, which I didn't even know was an option yet, so I would also appreciate detail on how I can discern between the two in the future - characteristics etc. 1. 2. and I also have several of these, ranging in size/condition some with enamel etc - this one as I'm taking photos I realized the tooth part of it might not actually be what I was thinking for this one, but the rest have the more rounded tooth, anyhow, are these jaw pieces with broken teeth like those above to be identified?
  3. I will be taking the family on our trip to Kemmerer the 2nd weekend of June. This is the trip sseth offered up to auction back in Nov/Dec. My 4th had to back out due to a family issue so I posted the open slot under the rolling auction if anyone is interested in joining us out there under sseth's guidance for 2 full days of eocene rock fishing the green river. I will also be hitting Big Cedar Ridge in WY for some cretaceous plant fossils on the 6th and U-dig in UT for some cambrian trilobites for a couple of hours on the 12th in case anyone's looking for digging company that week. I tried reaching out to both Black Cat Mountain and Thiessen Quarry in OK looking for a solo trip on 6/15, but I haven't heard back from either. If anyone has a lead they would be willing to share I would appreciate finding a way to connect with one of them before we go. It's shaping up to be one heck of a trip and I look forward to sharing pics of our adventures when we return. Let me know if anyone is interested in trying to coordinate times at any of the locations.
  4. I bought two unprepared fish nodules from a dealer at a show and have started to prepare them. I'm a total noob when it comes to preparation. I've prepared a few trilobites from wheeler shale but that's about it. I have a Paleo Aro and a Paasche air eraser. Can you all take a look at what I've done so far, and help me to understand what I'm seeing? Obviously I just got a fin, but I don't understand what the big long part is in the middle, or how the fish is oriented. A lot of the black/brown layer has chipped off while I've been working on it. Is this an actual 3-dimensional fossil? I expected it to be just like a thin plate, like Green River fish. I have only used the Aro, haven't tried messing around with the air eraser yet, although wouldn't the air eraser chip off the thin brown layer just as badly?
  5. Can anyone ID this brown turd-looking thing above the fish?
  6. Hi Everyone, About 20yrs ago, I was given an unprepared fossils from a friend of the family (from Oxford in the UK). Admittedly it's taken me 20yrs to get round to preparing it, but now that I have, it seems pretty interesting. I did a basic preparation on this tonight and the fossil fish has come up really nicely. I've no idea when or where it was found as it was simply given to me to practice on. Any guidance from a few fish experts would be brilliant. The matrix was a very hard material (I think a limestone). The total length of the fish is 6 inches. Any thoughts?
  7. Hello everyone! Saturday, I went hunting again at the Zandmotor. Even though it is only 25 min away by car from my house, I don't get to hunt there often. First off, a small introduction to the Zandmotor: The Zandmotor is a big beach extension between Kijkduin and Ter Heijde, and it is made by man. The fossils found there are mainly seashells (clams and cockles), which fill the beach, and also mammal bones, which most people search for (most just ignore the seashells, which leaves more for a seashell-lover like me ). Sometimes great white shark teeth are found too, but they are the only species of shark found at the Zandmotor (from what I heard); it's a mystery as to how the shark teeth got there. All the fossils date from the Pleistocene to the Holocene periods (so they are relatively young). The reason that fossils can be found there is because the fossils got dredged up from the North Sea, which is very rich in fossils; the case is similar for the Maasvlakte 2 and the Hoek van Holland, two other locations on the Dutch coast. The Zandmotor actually just looks like any other normal sandy beach, and many people just use it as such. In fact many people that regularly go on the Zandmotor ignore that fossils can be found! The Zandmotor is also a popular place for taking your dog out for a walk. Now my trip report: When we arrived, it was still rather cloudy, but at least it wasn't raining and there was little wind. We did put on our fat coats and were well prepared to face the cold. The small crash of the waves and the squawk of the seagulls filled the air. In the background, the harbor could be seen. Lucky for us, the weather quickly cleared up and gave way to a nice blue sky.
  8. Okey donkey, my sister just brought this to me. Found hiking in a dry riverbed in Paso Robles, California. The area and rock tell me it is Monterey Shale Formation (Miocene). I said it looks to be fish, but the size of the ribs don't seem to fluctuate which would make it a long creature. Now there is an outcropping of Pipefish about 15 miles south of here, could it be one or ? As you can see from my hand, it is about a 1 1/2" long vertibral column. Thanks, caldigger
  9. The tiny tooth is Jurassic, from the Oxford Clay at Whittlesey. I think it's marine reptile from its shape, but not sure which one. The second one I found last year, and I'm baffled by it. I think it might be fish. Any suggestions would be very welcome!
  10. First off, I want to thank Doren for sending me a small flat rate box full of STH matrix for me to try sifting through. I still have quite a bit of fine matrix to sort through but already I've managed to find hundreds of specimens. I've found quite a few Carcharhinus, Cetorhinus, Galeorhinus, Squalus, and tons of ray teeth. When I'm finished with all the matrix, I think I'll write a follow-up post with all the nice specimens I found. I'm having a little trouble identifying various species of rays - maybe someone has a literature suggestion to help me get familiar with different tooth characteristics? From what I can tell from other posts, the features that differentiate some ray species are quite subtle and to my untrained eye, very difficult to distinguish. I wouldn't mind some ID help with these teeth in particular. Scale to the right is in mm. If you could also comment on how common/uncommon these species are and what position they are in the jaw that would be immensely helpful as well. Also, maybe someone wouldn't mind making a list of the species found at STH and rank how common they are? Also, does anyone have suggestions for removing the last bit of silt/sand from the crevices in the teeth? I've tried water and gently stirring but that does not have much of an effect. Thanks for your help!
  11. I only had 4 hrs to hunt today but I still managed to find one large thick piece of fossil turtle shell, possible fish fossil bone, mosasaur vert and 3/4 of a point. Such a pretty day.
  12. From the album Nigel's album

    Green River Formation, Wyoming. Fish is 2.4 inches long
  13. 12 hr NSR hunt on a beautiful day. I found a nice variety of fossils & artifacts. My buddy made friends with a couple of copperheads.
  14. I found this in the Devonian Mahantango Formation from a road cut in western Maryland. Is it a fish tooth, and if so, what genus or species?
  15. From the album In-Situ Shots(various locations)

  16. Hello all! Recently I was given this fossil, and I have no idea what it is or where it came from. Wondering if you guys could help a non-expert.
  17. I started the preparation that @snolly50 won on my auction. Here's a pic of the fish as I received it.
  18. From the album Cretaceous

    Enchodus Jaw Piece Upper Cretaceous Wenonah Formation Big Brook Colt's Neck, N.J.
  19. I just had to show this one off! I saved the Notogoneous from a terrible fate of never being prepped! My buddy thought he was missing part of his head after he roughed it out so he set it aside. Notogoneous is my favourite fish so I took a gamble and had it prepped out, to my surprise it was all there with a wide open mouth! Notogoneous: 24 1/8 inches (61.28cm) Diplomystus: 15 inches (38.10cm) Knightia: 7 inches (17.78cm) Cockerellites (Priscacara): 5 3/4 inches (14.60cm) Entire panel measures 63 1/2 inches (156.21cm) wide by 22 inches (55.88cm) tall.
  20. Hi all, Here is a partial jaw of a porcupine fish. It was found in Lee Creek, USA, and I think that it's from the Pliocene period. Does anyone know exactly how old this fossil is? Also, is it possible to set a species name on this? Best regards, Max
  21. Ok, as promised I will be posting some of my finds in Cyprus island, for ID, discussion etc but while in my "chamber of the million unidentified things" trying to get some decent photos and find similar online, I decided to take a small trip yesterday April 1st and BOOM I see this. (photos) is that a whole fish preserved like inside out and all? Or has mother nature pulled an April fool's day joke on me?? I wonder if I can see inside using x-ray.. I really want to find a doctor and try do that. Let hear it from the experts here 1st tho. I have cleaned the specimen and carefully removed what was surely aged dirt etc. I'm trying to get some more photos online, as I see here I am having a size limit issue. I case in the photos is not clear, at the "tail" part you can notice that inside there is this dark crystal like material, the one our ancestors used to start a fire and used it to make tools and weapons with. the two round "eyes" appear to have that material inside too.. which is confusing, coz tail and eyeballs are not exactly same material, then again maybe those are not eyeballs and it is upside down (because when u flip it, it resembles one sort of fish look, and when again, another one. a "fish palindrome" lol) or there is various stuff and materials inside, because outside you can see indication of dark almost black contents, and mostly those parts are mat and not glossy. Also in some places mainly on one side. u can see many brownish dots like freckles is it called?

  23. A few weeks ago I was on a hunt and picked up a few nice Isaurus sp. teeth, some hemi's and seen some bone frags. I saw this sticking out of the mud at river's edge and figured it was more than just a bone but it was completely covered in mud. My eyes trained for teeth, I put it in a bag and continued on. When I got it home, I ran water over it and the small teeth started to be revealed. I couldn't believe it. I am not an expert by any means, but I assume its a fish mouth plate? From looking online, I don't see where it would be a drum. I have found individual drum and other oval fish teeth, but nothing complete like this or the round shape of these teeth. You can even see the replacement teeth in the bone in the photo where the ruler is horizontal. Two of the photos look the same, but in one, the fossil is laying on the teeth, and the other is a side view, if that helps. I spent the last few days searching online but couldn't find anything that specifically gives light to this. There is a small chip on the bottom in the center where the shade is darker, so it may be missing a small portion in that area (seen in the side view). Thank you for any information!
  24. Hi everyone, can anyone please help me identify this rock. I found in my little garden months after we had a gravel delivery. So it can be from any where. Thanks Bobby.
  25. About two weeks ago I bought this bunch of Kem Kem chunkosaur pieces in the hope that something interesting might be in there among the nondiscript bone fragments. There were some things that were identifiable. But this one piece completely baffled me when I looked at it more closely. I hadn't noticed it at first because it still had a bunch of matrix on it. But I soon saw some weird square shapes. These remind me of of the shapes some reptiles have under their scales on their skull. The bone piece already had a weird straight shape with a hollow in the middle. At first I assumed the hollow on the inside of the bone that was just exposed due to breakage. But I then cleaned it some more and a pattern emerged on the inside of the fold that I can only describe as a toothplate. I'm almost positive this must be some kind of jaw piece with a strange tooth plate. I know Kem Kem is still very much a mystery. But I've never seen anything quite this thoroughly bizarre before. Has anyone ever seen anything similar to this? Side with the "toothplate" visible as well as clear square shapes on the outside of the bone. It's still not completely clean, but the toothplate seems to extend futher into the fold. Flat outside edge. The square shapes end in half circles on this side. The other side of the edge also has similar patterns but on a different scale and not as clear. Other side with more subtle square shapes on a smaller scale. Both broken sides to show the cross section. It's also slightly asymmetrical.
