  1. Past hour
  2. Please help identifying

    Thanks for the info.! I didn’t think it was an actual beak just beak shaped☺️ but that would be an interesting find for sure! I appreciate you taking the time to help a newbie
  3. You could try your luck around Little Falls, but I've heard much of it has been posted as no trespassing. Alternatively, there may be some minor exposures on Route 28 anywhere along the West Canada Creek.
  4. Now does anyone know where I could go to find Triarthrus? I have heard of them being in the Utica shales but not sure where I can go where it would be exposed.
  5. Matching the coloration of a woolly rhino skull?

    I think they look lovely as is, no need to change either of them.
  6. If anyone has seen 3D printed fakes, Could you PM me some pictures? I really want to see how they do it.
  7. Matching the coloration of a woolly rhino skull?

    If you feel this is something you have to do, I feel it would be easier to darken the lower mandible than lighten the entire upper skull.
  8. Today
  9. Hell Creek Turtle

    Nice find is this with PaleoAdventure?
  10. Hell Creek Turtle

    Agreed! I was so disappointed that we ran out of time. I was particularly looking forward to learning how to do plaster jackets, though I still wouldn't have gotten to see how to get it back out of the jacket. This was much more of a learning trip for me than an acquisition trip. Walter kept asking me if I was sure I wanted to keep digging the shell out instead of finding another spot where I might find something I can take home, but I persisted on the shell. I did bring home some sweet little goodies, though, including a nanotyrannus tooth!
  11. Any chance for shark teeth around Ft Lauderdale?

    Fossil Beach, Is it possible that are any Megalodon teeth in that limestone quarry still? Sounds like a miracle with regards to it’s location. I was under the impression that it is impossible to find Megalodon teeth anywhere in southeastern Florida unless it was brought in with fill or planted. I would like to see photos of these Dade county Megalodons that you found. Thank you.
  12. Unkown vertebra north sea

    Does anyone know what this is it's from the north sea and it's 8 cm long. thanks in advance?
  13. Senckenberg Museum in Frankfurt / Germany

    Wow what a great museum. Superb pictures as well! Looks like it blows away my trip to the Denver Museum of Natural Science & History I took last week. I pray one day museums will adopt an adult only day once a month though.
  14. Middle Cambrian Stromatolites?

    Thank you Johannes! Very interesting, sorry stromatolites but having the imprints of trilobites seems much more exciting. I am wondering are the lines created from athropod plates / legs imprints left behind in the sea floor? Also, is the give-away the fact they have a groove down the center? Looking at the same large trilobites I found at the location I see how their bottom plates would make a trace fossil like this.

    Very nice tour; those are excellent pictures of some truly amazing specimens!
  16. Middle Cambrian Stromatolites?

    Material you show are mostly arthropod trace fossils, the lower ones in "Stromatolites 1.2" are Rusophycus isp. (nice ones, by the way). For identifying the upper left, we need pictures showing more details. Doesn't look like a stromatolite following this picture.
  17. Dino embryo?

    Mom is correct on this one.
  18. Microfossil extraction and preparation

    Since you have a laboratory environment, you might look into using lab grade 30% H2O2 to break down your shale. I can only use 3% Walmart H2O2 in my home environment which does work somewhat on soft weathered shale. I've always wanted to try liquid nitrogen but you can't do that in a home environment. With some limestone and other carbonate materials combining freeze/thaw with vinegar (5% or 10% acetic acid) or mild acid like acetic acid in low concentrations (10%) speeds up the process. Boil the limestone/carbonate material in vinegar/low concentration acetic acid, sieve it after cooling, put the bigger pieces of matrix in the freezer and wash the matrix residue that has broken down really well in water to remove any residual acid before searching/storage. Repeat the process until you get the amount of breakdown that you want. I never use strong acids or high concentrations of weak acids. It is not safe to use them in a home environment and they destroy your fossil specimens. These acids etch or may even dissolve the phosphate based vertebrate specimens (shark, ray, bony fish) that I'm trying to extract from the matrix. Even weak acids in low concentrations will dissolve carbonate based invertebrates. When using any of these methods, safety has to be your number one concern. Don't even consider using 30% H2O2 or strong acids/weak acids in high concentration in a home environment. Edit: I should have said something about clay and/or sand matrix. I take this type of matrix from different formations in VA/MD in 5 gallon buckets. Once home, I put the matrix on tarps and dry it really well in the sun. When thoroughly dry, I fill 5 gallon buckets about 1/3 full of matrix, add hot tap water and a few drops of detergent like Dawn dish soap, stir the matrix really well and then let the buckets sit overnight. The next morning I wash the matrix with water in a sieve (size depends upon what I'm looking for but I usually don't go below .4 mm and usually use 1 mm.) which fits over a 5 gallon bucket. I usually get about 90% breakdown on the first washing. If I get good breakdown I put the remaining matrix on cookie pans or if there are still lots of small chunks I put the matrix back on the tarps and dry it again in the sun. I repeat the above process as many times as necessary to get full breakdown. Most clay and/or sand matrix breaks down completely in two or three cycles. Marco Sr.
  19. Mom/parents are always wrong till you move out and start building a life for yourself. thats when all the stuff theyve told you over the years starts to make sence. Good luck. RB
  20. To me, this looks very fake. Not saying it is, just looks that way to me. I wish you the best of luck RB
  21. Are these surface collected or did you dig in the actual formation? Cool pieces though. RB
  22. Arkona Crinoid prep

    Nice specimen. Will you be filling in the cracks someday? RB
  23. Crabs are great..

    I belive you have found Tiny Tim the Tumido's little brother,,,, Tiny Tony the Tomido. The concretion that Tim is in measures 3 1/2 inches. Looks like some very nice preservation too! Tiny Tim had lots of problems with hollow legs. Im wondering if you will run into the same problem? Good luck though. RB
  24. Middle Cambrian Stromatolites?

    Hi Everyone, I've recently returned from a weekend trip to a fossil site in central Australia. The location contains siltstone laid from the ancient ocean once in the middle of Australia during the middle Cambrian. Both John R. Laurie and Dr P.D. Kruse have completed work on the site and have some publications accessible online. Along with a good collection of trilobites I came across a number of what I believe to be stromatolite fossils. The first image (1.1) was found on the way to the location about 150km before we reached it, the road cut through a much lighter shade of rock outcropping than we had previously seen. The formation appeared identical to the Arthur Creek formation, and judging from the geological surveys I have checked it should be part of the same formation. So keep in mind the first image is not from a known fossil bed, but is only from my best judgement part of the same formation. The remaining fossils in 1.2 are all from the known fossil bed, part of the Arthur Creek formation dating to the Templetonia (middle Cambrian). Top-left looks to me like a very typical stromatolite, similar to what is still seen today in Western Australia. The other fossils seem to me to be either the same stomatolite but seen at a different stage of weathering, or another type of stromatolite. I am interested to hear the opinions of those more knowledgeable! Thanks in advance.

  25. Central Australia - Arthur Creek Formation

    It has been quite dry here recently, no sign of kangaroo's or other larger animals, as they're most likely hiding out near the water holes. We did see a lot of birds though, large flocks of budgerigars (those same ones popular as pets, but wild this time), some wedge-tailed eagles and evidence of where a group of Australian bustard's had met untimely ends after being hunted by the local Aboriginal people. They call them bush turkey's and are quite popular eating, you can sometimes find the large piles of feathers left behind.
