  1. I am thinking of buying these 2 frog specimens from “Jiamusi” in China, do they look real or are they fake?
  2. Here is a few shots from the famous Norden Bridge in the northwest corner of Brown County Nebraska. This is one of the sites made famous by Morris Skinner and ultimately led to the discovery of Ashfall Fossil Beds. I was in the area, and was able to make another check mark on my list of famous fossil sites to visit. It should be noted that there is NO fossil hunting here. The river itself is federal land, the main quarry, a few km away is private property, and the bluff sites are part of the Nature Conservancy. However, it is a beautiful area to visit, and well worth it if you feel the urge to walk in the footsteps of famous folks. So, to start, here is the bridge itself: And a nice shot from the north banks, showing the strata of the bluff. Near the top is where many many vertebrate fossils have been discovered over the years, from frogs and snakes, up to rihnos and three toed horses and such. Another shot looking downstream on the Niobrarra of a spot known to produce many skulls and mandibles:
  3. Pleistocene or recent stuff?

    Dear TFF Members, I went yesterday for a fossil hunt in the sand pit I usually visit to hunt for Pleistocene stuff and I found several fossils, but some of them make me wonder if they are truly Ice Age or recent: First of all because of their size - the preservation of some of them was a huge surprise: For instance these: No only is the triangle shaped bone almost unscratched, but the two large ones are not hollow (which was normally the case): The other large bones have got a sort of white colour at the exposed edges - which is also something I have never seen before:

  5. I've been finding Pleistocene fossils along the gravel bars in the southernmost section of the Brazos River lately, but they've almost always been unidentifiable chunks or fragments of bone. Obviously I'd like to find something well-preserved enough for me to be able to do the research and find out what it actually is, but I don't know where to look. The Beaumont and Lissie Formations that run underneath Houston and the surrounding areas are both Pleistocene-age, but the actual river basin itself is just made up of alluvial deposits. Of course, this must mean that the fossils are being washed down with the current from some location further north, right? The Waco Mammoth site is several hours from my location, but I know that the fossils there were found only a mile or two north of the river itself. Originally I thought that this is where the fossils I'm finding must be coming from too, but I know that Holmesina, Bison, and Camelops skeletons used to be found in the bayous within downtown Houston before the city grew to the size its at today. As far as I know, there aren't any exposures of sediments like this that are also the age I'm looking for anywhere close to where I live. I'd really appreciate it if anyone with experience hunting southern or central Texas could point me in the right direction. I'm not asking for any specific sites since I know people won't want to give those up, just general areas where Pleistocene outcrops or exposures would be present. Thanks for the help!
  6. hello the west side of the Chesapeake Bay is famous for vertebrate fossils at sites like Calvert Cliffs has anyone found or know or finds of vertebrate fossils on the EAST coast of the bay? thanks
  7. HI. Folks! I'm going nutz behind my mask--and I have a trip to Miss. and Ala. scheduled.... never been to either state, and wondered if anyone can suggest areas for a legal hunt or two while I'm there? I'd appreciate any tips, particularly with specific directions. Thanks! Barby

  10. Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA
  11. Hello! Long story short, my fossil collection perished in a house fire when I was a kid. I realized a few years ago that I was a Real Adult™ who didn't have to ask for parental permission to buy stuff and could rebuild what I'd lost, so after acquiring my first piece of amber – a big fat spider in Dominican Amber – I was hooked. Researching and buying fossils has been so fun and informative; I've been burned a few times with fakes, I've celebrated rarities, and I love having a little museum in my apartment. This past weekend I did the Museum of Natural History Sleepover in NYC and had a blast talking to an expert in the dinosaur wing, something I couldn't have done without this forum and a total crush on fossil trading, learning along the way. My current stash is focused mainly on claws, teeth, bones, plates, and anything encased in amber. Here's my main collection, with detailed photos and labeled descriptions to follow. Also, if anyone has further identification, feel free to chime in. You're the experts. Detailed pics and labels to come.
  12. Hi All. I was unsure where to put this message so hopefully this place is okay. I teach 7th grade Life Science and we are soon starting our coverage of major animal types (arthropods, echinoderms, molluscs, chordtates, etc). I am hoping to put together a teaching collection that can be used each year as we do this. If there are members here who are willing to donate any/all types of durable specimens (harder for young teens to destroy) that could be used to teach students the key features of these phyla. If you are willing and able to share can you please PM me directly. I do appreciate it :-)

  14. Here is a thread to share some of your rarest partials that if whole would've been incredible specimens, but you know how it is sometimes... Yet they still amazing to own a piece of. I will start off by sharing a piece of the tail of a Probolichas Kristiae, an incredibly unique looking rare lichid trilobite from Oklahoma that would've of been incredible if whole of course yet this piece still has amazing detail and I am more that happy to own

  18. Hi everyone, I haven't been able to post much lately as I've been ill for a few months so haven't been getting out hunting as much as I'd like but I've had some good luck when I have been able to get out so wanted to share some finds! All are from the Carboniferous of the Midland Valley of Scotland from several formations, I haven't gotten round to photographing everything yet so I'll post some more stuff over the next few days. First some finds from the Lower Carboniferous/Mississippian marine Blackhall Limestone. Undescribed jellyfish, Fife Coast, 3cm across. Apparently a paper describing these is about to be published very soon. I'm told this ones a male, the bumps in the center being the male reproductive organs. This is by far the more common form, there is a second spotty form known from this formation which I found a specimen of a few weeks back and will post shortly.
  19. Quick question, I am aware it is illegal to export vertebrate fossils from China to other countries. Is it legal to ship them to the U.S. from Hong Kong, and Thailand?

  22. Bones from Sharktooth Hill

    Hello, I returned from Sharktooth Hill (Bakersfield) with a bunch of bone fragments that seem to be mostly whale ribs and unidentifiable fragments. But I did have a few pieces that seemed distinctive enough that I thought someone more knowledgeable than me might be able to recognize. The third one from the top looks very similar to something another member posted (though not identified) - one side looks exactly like driftwood (is this known form STH?) but the other side very different, as shown in the pics. Someday I hope to be on the help-delivering side of the equation in this forum. Until then, much gratitude!
  23. Hey everyone - It's Christian. For the past few months, I was inactive on TFF as I had a lot of schoolwork.. But now, I've got a lot more time on my hands - which means that I can get back to all things fossil related This of course includes making preparations for my 3rd Møns Klint Fossil Excavation (MKFE - the fieldwork aspect of my Møns Klint Fossil Research Program). I'll be going for 2 weeks, in mid-August - I'm really excited! As I said in a post from a few months ago, the collection policy of this MKFE is essentially the same as last time's (cephalopod, crustacean, echinoderm and vertebrate material). This time, though, there'll be a bigger focus on articulated and/or associated material - eroded sea urchin spines and belemnite fragments are getting too numerous... On the first days of the field trip, I'll have to do quite a bit of prospecting for new sites to work at, because there's a chance that the landslide spoil heap from last year has most likely been washed away by the waves. I'm already having some ideas of particular projects for this field trip, which include a comprehensive collection of washout microfossils - to determine relative abundances of various faunal groups. Another project is the in-depth analysis of fossil material from different layers of chalk - which I hope will yield some zone fossils. Of course, I'm still hoping to find a lil' mosasaur tooth I'll also use this field trip as an opportunity to donate to the GeoCenter Møns Klint some of the fossils I found during the 2nd MKFE. I'll keep you guys posted! Stay tuned I'm so excited to getting back there! -Christian
  24. Hello Fossil Forum community, This is my first post. My name is Ben and I recently learned about the Peace River. After getting my fossil collecting permit, decided to try my hand at it! I loved collecting trilobites and sea animals in upstate NY, so to know there is a place in FL with abundant, remarkable and unusual fossils, makes me so happy! I live about 45min away from Paynes Creek Historic State Park; here the creek and river join. I collected these fossils just past the border of the park. I would like your help to try to ID them, please! Where Paynes Creek (right) meets lazy Peace River (left) Here are some fossils I think I know, but I am still unsure. Horse tooth? Dugong rib bone? (very dense feeling, like lead): Left: barracuda tooth? Right: claw? Back of "claw": Front: Front, zoomed: Side: Many thanks for any help, I love this River! Thanks for your time, Ben
