  1. Hello all, Found this on the Maryland side of Assateague Island National Seashore while fishing. Not sure what it is or if it's even a fossil. The grey matter is hard as a rock. Any help is appreciated. I can post more pics if needed after work. (Didn't think to put a ruler with it)

  5. I found these fossil crabs. Previously, a few years ago, I had already extracted some, I prepared them by removing the slightly hard earth that covered them, but there is a thin layer from where the crab starts (where I saw it and extracted it) to the layer that worked which is the one that is less damaged. Therefore, it is somewhat fragile and I wanted it to be a more solid piece that I would not be afraid to manipulate and that could break. I wanted to know what is suggested in these cases (as long as it is necessary and does not spoil the fossil, if it is usually done it is the first time I do it) so that a fossil is not so fragile and thin, such as putting it in the deteriorated and less showy part a layer of plaster or something like that. I hope I have explained myself, sorry if my English is not very good, I leave you photos of the crabs. Thank you very much! here is the piece, the current one, the one I found recently (little work, without discovering the main part) the same piece seen from the side the same piece seen from the part where I found it This is a crab that I found a few years ago that is already working. The view is from the side (You see that the piece looks a bit thin and fragile) the same piece seen from the part in which it was found the same piece on the worked side

    UAE Crab

    Hello. Do you guys think I can prep this crab from Al Ain (part of the United Arab Emirates)? It looks pretty beaten up, but I am hoping the ventral side might still be there. I have tried preparing urchins in this matrix with a very diluted water-vinegar solution. Do you think this could work for the crab as well?

    A Cold Day in the Glen Rose

    Back in the Fall I got permission to visit a small exposure of the Early Albian Glen Rose Formation. Unfortunately the property owner told me that I could only visit on a Friday. We had planned a visit a few times but for some reason or another the plans kept falling through. Today I finally got the chance to visit. Sadly today was one of the coldest days this month. Temperatures hovered in the low 40s with a wind chill factor in the low 30s. After visiting the site I checked out a couple of other spots in the area that I had previously visited. The finds were tough to come by, partly because it was so hard to focus while strong wind gusts chilled my mind and soul as I stared at the ground. But for what today was, I am happy that I at least found something new. Today's new find was this cool partial sea star arm. @erose found one a few years ago in the Glen Rose Formation but this one seems different from the one he found. I have had a lot of success finding claws of the hermit crab Pagurus banderensis at one of the other sites I visited. Today was no different.
  8. I will be working in western Washington this summer and I was hoping to squeeze in a day of fossil or fossil nodule collecting. I am looking for recommendations for one day of recreational fossil hunting.

    Oxford Clay - Hybodont?

    Oxford clay, Peterborough Member, Jurassic, Callovian, near Yaxley in Cambridgeshire. I spent the morning getting muddy in wet clay, and found this. I think it might be part of a hybodont spine, or other ornate fish spine. I've collected a fragment of hybodont spine from this site before. The surface does seem to be enamel, and the shape is slightly curved. Any assistance greatly appreciated.
  10. A fossil crab which was given by a friend long time ago. I am just wondering if anyone knows any more details about its ID (possibly from Australia). Any information would be much appreciated There is a shell attached on the claw, which I find cute.
  11. Hi! I found this fossil crab from Indonesia. Miocene-Pliocene. To me it looks really nice. But I have heard of fake fossil crabs from Indonesia. Is it real? Regards
  12. Here are some photos of my 2nd ever fossil hunting trip on Saturday January 8th, 2022. On Friday Jan. 7th, was my first fossil hunting trip, which I posted a few days ago, obtaining mostly exogyra oysters from the North Sulphur River. So I went out the next morning in the rain to Jacksonville, TX, about an hour from me. I stopped along Hwy 69 just north of Love's Lookout, where there are steep rocky cliffs on either side of the highway. I only stayed an hour, as I was soaking wet. But I managed to chip away at several of the red rocks in the area (sorry, I don't know the geologic ages), trying to separate layers and see what could be exposed. I brought 13 samples home, just based on some indentions, bumps, or various colors. One of the samples looked like maybe a clam. It wasn't until I got home and cleaned them up a little did I start noticing what I found. Two of them have crabs in the matrix (it wasn't a clam). One of these with one crab also has 2 scorpions on the reverse side. Another rock sort of looks like it has an orthoceras nautiloid in it. All the others I'm not sure if anything or not. See my photos and comments below. I'll post more photos with close-ups and ask for help with ID in the "Fossil ID" section. All in all, I'm very excited and pleased with the two fossil matrix rocks for sure with the crabs, scorpions, and an insect. Worth the trip. 1) Total take: 13 Photo#1: 2) Four crabs and one large insect (not sure what kind). Unfortunately, I think I knocked off the largest one's arm when I was chiseling on the larger rock. Also, I need to know how I can seal these cracks. This piece is extremely delicate/fragile right now. I don't want it to fall apart. I'll ask this question in the question section also. Photos # 2a, 2b, Biggest one, missing an arm. Can still see its pinchers/claws. Photos # 2c, 2d (you can see the smallest one to the front right, with the insect hovering right behind him, can also see the pointy spikes on the insect's arms.) Small crab and insect, from different angles. Photos # 2e, 2f, 2g, 2h Small crab to right of big one (mama), in middle, (or below mama in this next photo). I didn't get a real good photo of him up close. Photo # 2i Crab near the back. Still covered with some rock matrix. I could use some suggestions on how I could uncover him some more, or should I not even try? You can see one arm and pincher, and part of the body. Photo # 2j And here is the underside of this matrix. Photos # 2k, 2l 3) Crab on top side, and 2 scorpions and a crab (or crab arm and a leaf?) on the underside. Photos # 3a, 3b, 3c from top side. Crab on far left. Any idea what the yellow lines are? Underside. Full scorpion on left side. Smaller scorpion on right front edge, with a crab pincher to the right of it. Photos # 3d, 3e, 3f, 3g, 3h, 3i, 3j, 3k, 3l 4) Strange streak pattern on front, with large insect (?) on underside, left of center, with what looks like a long tail. Photos # 4a, 4b, 4c 5) This one sort of looks like an orthoceras nautiloid buried. From the side view you can see a cylindrical bulge on top. From the edge view, I can't really tell if the cross section of the nautiloid is showing. Any agreement? If so, what would be the best way to remove more rock and get more of it exposed? This is something I don't know how to do yet. Photos #5a, 5b, 5c, 5d 6) And finally, here are the remainder of the rocks. I'll ask if they might be anything in the Fossil ID section. Photos # 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h, 6i, 6j

  16. Howdy yall! Its been a while sice I posted because on the same day I collected these concretions me and my digging buddy collapsed a chunk of the cliff onto ourselves and broke a few bones (Its all okay now and also congrats to whoever collected the concretions in the rocks). But all I have is a dremel 290 and these are gigantic concretions that I dont think I can prep by myself. I was just wondering if yall though it would be better if I just bit the bullet and got an actual set up or a ball park price to get someone else to prep it (I really want it well done another reason to get someone else to do it cause im garbage at prepping)
  17. Hi. My Family has had what we believe is a crab fossil for some years. It was passed onto us about 10 years ago. We are in Australia but I believe it possibly comes from Indonesia or East Timor originally. My question is whether Is anybody able to help me confirm whether this is a real fossil or artistic impression and also what species the crab is. If real, how would I go about determining a value? Much appreciated Marcus 142171155_Photos(2).zip
  18. Hello All, (WARNING: FIRST TIME CRAB PREP AHEAD) A friend of mine came across a small concretion (2.5") on a marketplace website and picked it up for me. It was already cracked open right across the equator, and exposed a small crab. (I'm assuming from Washington State but anyone that can weigh-in on the species is appreciated.) As per the pictures, the Crab itself has the body and the claw separated into different halves of the split. Reading up on the forum I decided to glue the concretion back together and air scribe my way back down to the Crab in the hopes of consolidating all the pieces into one specimen. After a few minutes of scribing I discovered a second Crab in the top section of the stone well above where the first one is located. Now I'm stumped and would like to ask the forum if they have any recommendations on how to proceed.
  19. After a lengthy hiatus, I was able to return to the only known fossil collecting locality on Guam, situated south of the Orote Peninsula on the Philippine Sea. Pleistocene (?) crab fossils can be found by beachcombing the beach gravels between the high and low tide marks at this site. It is thought that they were scooped up during dredging of nearby Apra Harbor in the 1940s during development of the navy base, and deposited on the opposite side of the peninsula as dredge spoil, and are likely late Pleistocene to early Holocene in age, but without knowing the source strata, it's only a guess. A publication dating to the 1950s identifies the fossils as several species of "mud crabs", extant species whose living representatives can be found on the same beaches as their fossil ancestors. They occur as compressed body fossils, jasper-brown in color, in a lime mud matrix. Carapace with leg segments are the usual finds. Claws are very rare. The site is gorgeous, but in the direct tropical sun, it can get hot. There's always some interesting wildlife as well, including hermit crabs, eels and octopus in the shallow water, and the occasional monster 2-foot coconut crab--the largest land arthropod A few hermit crabs Blue starfish Moray eel The giant coconut crabs (below) are getting increasingly rare as they are quite the delicacy. This is about an average size for an adult. They're best spotted at sunset

    Crab abdomen prep help

    So I'm prepping this crab I got from Indonesia but the bottom is looking a little weird one part of it looks like a piece is flipped over is that possible? Also it's very very fragile.
  21. Dear all, would like to know if the following crab fossil is genuine before I purchase it. Have appended 2 videos in this post. I’m aware there are quite a few fake carvings marketed as genuine fossils, but I’m not sure if this specimen is a real fossil or a carving, as it appears legitimate due to the intact matrix. Would like to know what the experts think. Thanks very much! IMG_7149.MP4 IMG_7148.MP4
  22. We are in country wide lockdown again and after a week of doing too longer days working I have decided to do another "sanity crab". The point is to force me to take breaks while working from home. So I cleaned the prep station from all my "nibblers" and will dedicate my time to this one. And straight off the bat its going to test me - its a mudder - not solid stone, and the exo is powder... Looks like a Tumido so far...
  23. Really beefed up my collection this year: Amber: Spent a while with my trusty loupe combing through Chiapas amber sold by the gram and found a very uncommon flower petal. The seller took a moment to offer up a page on his phone about the healing properties of amber, and he gave me a polite nod and laugh when I said I'm more interested in the scientific properties. I like dead stuff. Big Claw: Always wanted a thick beefy claw! Labeled as a Carch claw from Kem Kem but after reading some of @Troodon's posts it could be a Spino or generic theropod. Really love the shape of this thing. Crab: Unfortunately about 20% of the crab's lil' butt was crushed sometime between purchasing and driving home. He's so delicate. There's a nice interior view of the underside of the carapace now, though. Any info about this guy would be appreciated! Skinny Theropod Claw: A little rough around the edges but I was really drawn to the curvature and sharpness of this one. Labeled as just "theropod" so I'm not sure if it's possible to tell what it's from. I can post more photos for identification.
