    Interesting Jurassic coprolites

    These two coprolites have the most visible and interesting bits to them of any I have found. I've been trying to work out what the bits are, and I think they're bits of fish, from the colour and size, but I'd value more opinions! They are from the Oxford Clay, Jurassic, Callovian, Peterborough Member, and the first has colours I associate with fish remains I've found on the site. I don't really understand the dark pattern on the back. ETA: Sorry, I think this should have been posted in the coprolite sticky!
  3. Lots of our members collect at the Calvert Cliffs so here is something new to lookout for. S. Godfrey et al. describe new coprolite discoveries from the cliffs. https://riviste.unimi.it/index.php/RIPS/article/view/17064

    Cretaceous coprolites or nodules/concretions??

    Are these coprolites or simply nodules/concretions? I have zero knowledge on how to distinguish a coprolite, other than that these materials have a distinct, smooth shape that I could certainly envision reptilian poop looking like. But so do concretions oftentimes. These come from the Bladen/Tar Heel formations of North Carolina from an area known to preserve coprolites. Btw I read the coprolite ID thread and these appear to meet some of the criteria, although they’re not porous enough for the “lick” test, and I haven’t had a chance to view them under a microscope yet.
  6. Hi I recently bought a small 4cm 'coprolite' from a commercial supplier. Do you think this is likely to be a genuine fossil from Bull Canyon or is it likely to be a fake. Is there any way I could tell?
  7. I see on the web many deferent looking specimens being sold as Dino Coprolites. From what I’ve read on the web, most of these specimens are thought to be purely geologic. I was able to purchase 14 slabs labeled as Dino Coprolites from Utah for a very reasonable price so I bought them to see what I could see under a microscope. Chemical analysis and analysis of thin sections are much better ways to approach this. The individual pictures of the below 5 slabs (one is an end cut) were taken with the pieces wet and the close-up pictures taken with my microscope were taken with the pieces dry.
  8. Although I haven't been beach hunting much this winter (fishing was great until a few weeks ago), I rooted around for my shrimp coprolite burrows. Lately I have been finding less of the cylindrical 1-3" long burrows and more broken pieces. @Carl @GeschWhat are the experts on these things, and lately I've found more of them on the beachs than shark teeth (Covid-19 opened the interest in beach combing so more competition for teeth.) Difficult to get much resolution, even enhancing the contrast, but this is a scan of most of my collection:
  9. Today I was looking at fossils that I have paid any real attention too in quite a while. I figured that I would try and organize some of them and I started moving containers and pulling out concretions that contained coprolites. The pieces that I was working with were larger pieces, and that is what this post will show. I have found coprolites in the Essex (Marine) and Braidwood (Fresh) biotas. Many collectors in the past would skip over coprolites, just like they did with Essexella asherea Jellyfish, but that is not me, I would pick them all up. Mazon Creek coprolites have been known to conta

    Dinosaur coprolites

    From the album: Dinosaurs

    A chunk and a slice of dinosaur coprolites bought at a nearby rock store. Species, location, and age unknown. Despite being what they are, they both have a nice red coloring.

    Are these coprolites?

    Hi all, I recently found the items below at Calvert Cliffs State Park (A-F) and Matoaka Beach (G-I) in Maryland (both Miocene exposures). Image scales are in inches. I'm not sure what these are. Could some or all of them be coprolites? If so, any ideas as to what kinds of animals they came from? Thanks for your help!

    coprolites with seeds, near Flagstaff, AZ

    Hello! As a new member I am excited to learn from more experienced folks on this great forum. We found these coprolites (I think that is what they are) near the Little Colorado River, near Gray Mountain, Arizona which is about 45 mins north of Flagstaff, Arizona. They were both found on the surface. We go to this area to rock hound for jasper, agate and petrified wood, which we find in plenty. Can anyone tell me: 1. Are these coprolites? 2. What kind of seeds are fossilized? 3. Based on location and seed id, who pooped these out? Thank you very much! I am also about to post pics of what

    Dino poop or just a rock?

    I was wondering if this could possibly be a coprolite? Or just a rock that has formed this way over time. Found in the Rocky Mountains of Wyoming. Thanks for your input!

    Rhaetic fossil

  18. I donated 20,000+ Eocene marine Virginia coprolites to the New Mexico Museum of Natural History and Science in 2015. There have been several formal presentations given on these coprolites to date and a major paper is in final review. To see numerous coprolite pictures and read about/see previous presentations check out the below TFF link: http://www.thefossilforum.com/index.php?/topic/50059-what-ate-what/& A copy of the latest poster presentation given on these Virginia coprolites at the GSA Annual Meeting in Phoenix, Arizona, USA on September

    Help Me Out

    After a little research I think this is coprolite. Rock on one side and something that resembles poop on the other side. See next post for reverse side. Size is 1 1/4 inch by 3/4 inch by 1/4 inch

    Brazil’s Triassic Coprolites

    For those who are interested, this paper on Brazil’s Triassic Coprolites is open access till July 15th. It’s a rather extensive piece, and I must admit I could only briefly skim it, but I imagine others on here may find it very informative. https://onlinelibrary.wiley.com/doi/10.1111/let.12251 PDF version: https://onlinelibrary.wiley.com/doi/pdf/10.1111/let.12251 perhaps it might peak @GeschWhats interest?
