  1. Sauropod19

    Calvert Cliffs, MD, USA

    Hi all! I hope you are well! I recently made my annual trip to the Washington, D.C. area, which always includes a trip to the Miocene deposits of the Calvert Cliffs. I think I have a general idea on these IDs but wanted to confirm with others, especially the first two sets of images. I’ve tried to group like fossils as well. Thanks for looking! 1 (ray dermal plate?): 2,3, and 4 (otoliths?): 5, 6, and 7 (with 6 and 7 magnified at the end, respectively; cetacean ribs?): 8 (crab claw?): 9 (ray mouth plate part?): 10 (?): 11 (third image is root zoomed in; cetacean tooth?): Plus, here are a couple of finds that I just wanted to share for fun! Thank you again!
  2. Paid another visit to the old road cut. Didn't find much, save for the usual little gastropods and one small Pulalius carapace. Headed to Colorado tomorrow, and will get some photos from the Florissant quarry. Peace!
  3. After yesterday’s (4/23/24) hunt I decided to go back today after work. Let me tell you all, it did not disappoint! In total I found ~36 fossil decapods. 23 crabs, 12 shrimp, and “1” lobster. This brings my total cont from today and yesterday to ~49 decapod fossils. Also to note is the scale of the cutting mat in the background, every square is 1/2 inch for scale In regards to the “one” lobster it is in two pieces that might or might not belong to each other, they were found in close proximity to one another and have similar mineralization color and the size of the tail section could fit a lobster of this size. This specimen looks most like Linuparus grimmeri, I have two other examples of this species form much higher in the Britton shale, one found by me and one by my father, another note on this specimen is the size of the mandibles on the under side. Next up on the list is the best preserved and looking shrimp fossil of the day, I don’t have an ID on these guys yet, if anyone has any ideas please let me know. In all the only thing missing is the tail fan, it still has its head, tail, and even some leges and its two claws/pincers intact, in order shown is the top, bottom, left, and right sides. Now for more crabs, a good number of crabs found on this hunt had bits and pieces of their underside, legs, and claws here are the nice ones. Crab with imprints of the claws and partial legs. Another crab in similar shape but with a little more of the legs on the underside. Another crab with a portion of the underside of the crab carapace showing. Here is the largest crab found in the past two days, and with a good portion of the underside still preserved and in ok shape! Now here is something I was not expecting at all today, a small sharks tooth, not something I’ve never found but it is now the oldest I have collected. To round everything out I also coveted a small Inoceramid clam half that was in good condition for the sight, as well as some larger Baculites for the strata that I know of, and a set of two Gastropoda and two clams. This will provost be the last hint for the week, we have some rain forecasted for the end of the week and the weekend so here’s to some good erosion.
  4. I don’t post on this forum and much as I probably should so here’s to changing that. Had quite the eventful afternoon hear in the Dallas area in the Eagle Ford. Found the most crabs I have ever found in my life, no ID on any of these but feel free to give me your thoughts. This was the first find of the day and got me stoked for what else I might be laying around this sight. Within 5ft of the first find I found another decapod. This was when I realized what I was in for, Crabapaloza! These next two were found within 2ft of each other. The next surprise was this assortment of fish bone, this is my first time finding any bone at this location and is currently the oldest bony material in my possession. Along with the visible fish bone was another vertebra not pictured and what I believe to be a small lobster or shrimp barely visible. A reoccurring theme, this carapace was found not to far from the fish bones as well For about 20-30ft of the exposure there wasn’t much, but again, I found more crab, center of palm, along with a gastropod shell and two pieces of ammonite, in this shape I typically don’t collect them but are a good example of the shape most ammonites and baculites are in. At this point things started to slow down, but again, another decapod. And again not to far from the last fossils, another crab and a decent ammonite, for the area, within 3ft of each other. And yet another decapod for the bag And at last, on my way back and on the way out, I gave a quick look behind where I inserted into the exposure and to my surprise, one last crab, including parts of its legs. I don’t get to this site too often, as it’s quite out of the way for me, (and is wishy-washy in its production rate) so when I do go, I make the most out of it - and today I can’t say I’m displeased at all.
  5. Hello everyone ! I have stored these crabs a couple of years ago, while storing them they cracked (I suppose it is due to the internal humidity, they were found on a sea coast). I have the paraloid to apply them, but there are these cracks that I have to fill somehow so the paraloid doesn't leak. What material do you suggest as filling? And please know what percentage of acetone and paraloid is in the mixture? Thank you all ! greetings ! ps: the material that covers the crabs is hard sand EDIT: The reality is that I don't have much of an idea of how to prepare them, I was thinking of applying a layer of paraloid on one side, also filling in the cracks on something (the one where the broken crab can be seen, the place where it was exposed) and working on it on the other side.

    Crab exoskeleton/cuticle?

    Microfossil found at the Clark Quarry in coastal GA, USA 0.5 cm width across Was thinking it could be some kind of crab cuticle but did not have any comparative material and can’t find any. Thoughts as to what it might be and possible species?
