  2. how to protect fossil fish?

    i just got this knightia fossil recently and i was wondering if there anyway to protect it from flaking because they look pretty thin to me. im only an amateur collector and joined the forum recently so i'm don't know much about stuff like this.
  3. Another Fossilized Nut?

    Thank you for the friendly reply, I didn’t read to the conclusion of that thread and should’ve taken the time to do so! I’m very grateful for the info, it’s actually quite fascinating

  5. First air scribe

    Thanks Kane Right now it would be general purpose, later on I might get two specific scribes for bulk removal and fine detail. I looked at the schematics and it does have two gauges, so I should be able to control both the range and maksimum pressure afterall. I'm ordering a moisture trap now, are there any air scribe tips worth getting straight away? Best regards
  6. Show us your plastic dinosaur

    I wouldn't mind that in trilobite print

    Hi, Coco
  8. Fossils Magazine

    I think it was back in the late 70's to 80's that there was "Fossils Quarterly." I have a few issues somewhere. There might not have been enough of a readership to support two fossil collecting magazines especially with the rock and mineral magazines also having fossil articles from time to time. It's tough to keep a magazine going. A lot of work likely went into that first issue but then something happened to cause delays that led to number two never getting together. I don't think I've seen that one.
  9. ID-problem: is this really a Carcharodontosaurus sp. ?

    nice teeth you have there even though there not you thought they were and your English seems good.
  10. Show Us Your Best Dinosaur Tooth!

    Any and all self-found teeth deserves to be in this thread. A lovely tyrannosaurid tooth!
  11. Possible Lance fm. Ankylosaur Material

    I can not help much any ID's but I am hoping some of them are. That would be an awesome find !!

  14. Odd Coral from the Finis Shale

    I found this odd horn coral at the Lost Creek Dam site near Jacksboro, Texas. It's Upper Pennsylvanian, Graham formation, Finis Shale member. The horizontal wrinkling seems very organized, looking more like the ornamentation on a conulariid or some orthoconic cephalopods and the presence of dissepiments limit the possibilities some. The bottom was already broken off so I sanded it flat and polished it a bit for a look at the septal pattern but still can't seem to place it in it's proper niche. Dibunophyllum valeriae has been suggested and Lophamplexus sp. but I'm not convinced mostly because of the horizontal patterning.
  15. Had a quick walk down the beach the other day and it was actually pretty successful! Not many finds but they were all pretty sizeable! The largest one was half buried underneath the Johnny Mercer pier. It looked whole, and man I wish it was! Any ID ideas for the cusped tooth corner?
  16. Big Brook Finds!

    The first two are both concretions unfortunately. The three teeth from left to right are: either Croc or Enchodus (need more views to be sure), Enchodus, and most likely a Mosasaur tooth frag (need pic of other side).
  17. Big Brook Finds!

    The first item is either recent or Pleistocene bone. Might be something interesting. The second thing is an Enchodus jaw section.
  18. NJ Cretaceous? Pyrite

    Very cool. Was hoping to see pyrite from Big Brook, not to mention Chalcopyrite (rainbow pyrite!). It makes sense, given the water is metal rich and old shells are more likely to turn to this. Maybe someone will find an opal...
  19. Big Brook Finds!

    Another piece of that last mystery tooth. VERY worn by the river and broken. Has a slight curve that's still visible however.
  20. Big Brook Finds!

    Next, this appears to be a Native American Bead! My first Native item I've found. The bore holes on each side look drilled and the one side is flat, like a pendant that would go against the chest. This below also looks like a tooth fragment because of the hole on the wide end, and the smaller hole at the other. Finally here are some nice small teeth fragments as well! In order from left to right, they appear to be 1). Small Croc Tooth, 2.) Enchodus, 3.) Not sure maybe Plesiosaur? But very worn
  21. My Trilobite Drawings

    Latest... Some small mistakes I can’t fix, sadly, but ok enough for the book. (Fixed the species name to E. erbeni since this pic was taken). Pencils (HB, H, 3B, 6B), standard white paper.
  22. Big Brook Finds!

    Hi all here are some finds I cannot identify from Big Brook. Please let me know what you think! Any help is appreciated. First up I believe is some kind of pleistocene horse tooth fragment? But I am not sure. Thought it was a ratfish jaw frag at first from the other side, but it's like nothing I've seen. Below, this is what looks to be a fish tooth of some kind, but it seems to have some of the root attached. So no hole visible at the bottom. Slightly larger than a quarter in length!
  23. Let’s see your collecting vehicles!

    This is a 2010 photo of my old 1990 Toyota Camry with, of course, two wheel drive and low clearance. I took this thing many places where soccer moms won't take their Suburbans. Here it is in the desert north of Green River, Wyoming. The second photo is with a small jacket I threw in there. I had to take the horizontal part of the back seat out to make this one fit. I moved this jacket (still unopened) a few years ago when we moved and it either got heavier or maybe, just maybe, I got older. I junked the car about four years ago and Mrs jpc and I now use a 1995 Toyota 4Runner, seen below at two of my favorite fossil spots.
  24. Closer inspection to my collection of bone pieces from trips to the Lance formation in Wyoming has resulted in me wondering if I had a few pieces of Ankylosaur osteoderm in my possession. I want to know what the folks on the forum think.
  25. ID help

    The first is indeed a shark rostral node. Suggested reference: The taxonomic value of rostral nodes of extinct sharks, with comments on previous records of the genus Lamna (Lamniformes, Lamnidae) from the Pliocene of Lee Creek Mine, North Carolina (USA). Acta Geologica Polonica, 2000 John Jagt The second Croc osteoderm The third could be croc, could be Squalodon. I can't tell
  26. Lance fm Mammal Tooth?

    I just "rediscovered" what I believe to be a cretaceous mammal tooth, I placed it with the triceratops and edmontosaurus spit teeth thinking it was a sliver of one. Taking a closer look I think it could be the crown of a small mammal's tooth. I want to know what you think (It's about 7 millimeters long).
