  1. Do you see any obvious red fkag with this one? It is described as Zanthopsis dufouri, 8×7×5 cm, Eocene (47.8-56 m/y), from the French region of Aude. It llooks very nice, but what both attracts and puzzles me it that it appears ti be "sitting" onto its matrix, like a jewel on a silk cushion. What do you thing? An excellent prep work, or...?

  2. January in Texas is usually, weather wise, fantastic hunting. For seasonal allergy sufferers (like me) it can be miserable. But, we had a GREAT rain...two days of decent downpours and the temps were in the upper 60s, so, hoping the cedar pollen had been knocked out of the air a bit by the rains....I donned my mask and spent three hours out in the great outdoors and was I ever rewarded for my "perseverance"!!! hahahahha I had been hoping to find a Glen Rose Formation (Lower Cretaceous) Shark Tooth for a couple of years. I knew they could be found! Erich ( @erose) told me so and I believe him, usually! hahhaha. Well, Mother Nature decided to gift me one on this first hunt of the year! Plus, it was a bit of an Echinoid bonanza....nothing "new" to me, species wise, but a couple of really nice examples (four actually, of differing sizes!) of Hyposalenia phillipsae and a better preserved Paraorthopsis comalensis than I had. But what really tricked me was the Pygopyrina hancockensis. They are usually oval and i found this one (which turns out was just squished) and REALLY thought I'd found a Pygaster (which I DON'T have) so I got really excited until I got it home and realized I'd been fooled. Ah well, I found a Shark Tooth (Plus a nice big crab claw, too) so......it was a GOOD DAY. Shark Tooth Protolamna sp. 5/8 inches (15 mm) In situ (with lotsof Foramnifera Orbitolinas! A Quartet of Hyposalenia phillipsae echinoids: (Biggest is 3/8 inch) A very nice Paraorthopsis comalensis Size: 1/2 inch A very squished Pygopyrina hancockensis Size- 3/4 inch And a big honking crab claw - Pagurus banderiensis Size 7/8 inch
  3. I found a crab arm

    Im back at it again collecting more concretions. I found a bunch of small ones once again from the lincoln creek formation! But the wild thing is that I found this: Me and a bud were getting this concretion out of the rock when this arm was exposed. I plan to use a pin and hammer to get the tip of the claws out and I think I should super glue them onto the arm? And what can I do to preserve this arm because this is really cool.
  4. Help with fossil crab ID

    I'm looking for help with finding a genera from this chela/ crab claw, found in Cenozoic rock from Northwest Nelson, South Island, New Zealand. It is fairly weathered, and was originally split between two separate stones lying on the beach. A little reconstruction and preparation produced the result in the image. It was not in-situ so I am unsure which rock group it is associated with. I'm guessing it is either late Oligocene or early Miocene in age based on what I know of the area, but I could be wrong. I'm hoping there are some crab experts out there who will know what this is straight away, unfortunately I'm not well versed in decapods and seldom find them around where I live in the North Island.
  5. Hello. Does anyone know about the authenticity of the fossil crabs and lobsters below? I've seen them pop up on a few different sites and I'm suspicious because they all look nearly identical. Unfortunately, I don't have any information about age, location, etc. Thanks for your help.
  6. Enchodus jaw/teeth? And crab claw?

    My 29th trip to Big Brook and I decided to try to get there by an unnamed tributary I found on a map. Got to explore an area with little evidence of usage as shown by the paucity of glass and plastic. Overgrown and thorny and I think I saw my first bear footprint (photo below). Posted below are photos of what I think is an Enchodus jaw and two teeth and also what I think is a partial crab claw but much bigger than any I’ve found before. I also think I found my first arrowhead. Any info greatly appreciated.
  7. I purchased this from Indonesia, I have seen a lot available and was not real expensive. It is stuck in matrix that is very solid, the crab is exposed and polished. Hard to tell if it is real or some kind of cast mold in a concrete mixture for matrix. Wanted to see if anyone knew for sure or not. Is there some possible tests on the matrix to see if it is glued or concrete mixture?
  8. Monster Crab Claw?

    I found what I believe is pretty big piece of Crab claw or at least the biggest one I have or seen from NJ. Anyone else assist.. On top of this my find of the day was a monster Goblin tooth just shy of 2”
  9. Out of the countless New Jersey cretaceous crab claws I've seen and found this has to be one of the strangest claw partials yet. Seems to be an ornamented shell as apposed to the smooth claw textures that are typically found. Definitely a very interesting piece, anyone have any ideas on a possible species or if any ornamental crabs have found in nj cretaceous, or any other new jersey cretaceous hunters ever come across one similar? Definitely a head scratcher
  10. Crab? Pareidolia? What?

    Like all of us I pick up a lot of maybes/I don’t knows. I took this one home for a better look. With the loupe I think I see something and crab is my best guess. The whole piece is 1.5 inches. I don’t want to believe this is geologic. Your help greatly appreciated.

    A very nice Pulalius vulgaris from the Eocene Lincoln Creek Formation in Washington
  12. Hello all! I recently found a new spot that turns out is Walnut Formation. Finding lots of nice stuff there...big Echinoids - Phymosomas, a Tetragrmma and some little Leptosalenia mexicanas. But I've found a few things that I can't ID. @erose - I relooked at the presentation on Albian crabs you did for the PSoA last month and thought this one was in there, but now I don't see it? I thought you had collected one like this.. Thanks for any help, y'all! This little Bivalve looks like a Plicatula but those are not found in the Walnut? (According to the Houston Gem and Mineral Society Bivalve Book) And this other bivalve - closest I can come up with is Lopha, but again, not listed in the Walnut
  13. I was recently reorganizing my fossil collection and thought I would share some pieces I collected during Paleontology field trips in undergrad at Alabama. I'm glad I took thorough notes at the time! The demopolis chalk is a popular formation for finding Exogyra/ostrea/pycnodonte shells and shark teeth. We visited a site in Tupelo, MS many times for surface collecting. Some of the cool pieces I found were many fragments of a mosasaur jaw (top pic, top 2 slots), a Squalicorax kaupi tooth, a scyliorhinus(?) tooth, bony fish vertebrae, and bony fish teeth. I was told the dark fossils at the right of the third picture might be ray plates, but I'm not sure. Turritella in pic 1 are from a different formation.
  14. Location: Missouri Time period: Pennsylvanian Formation: Muncie creek shale Hello! I was hunting in one of my favorite spots and saw a very weird structure coming out of a Muncie Creek Shale nodule and what I think it could possibly be is a piece of crustacean exoskeleton! If I'm lucky that is! I am not exactly sure why I know its different but it does not look like crushed shells from other brachiopods in the area and looks to be layered horizontally. My personal theories: Weirdly preserved Brachiopod, Crustacean Exoskeleton, Natural formation that I have not seen in the area before or something else entirely. I would love to know any information and would love to use this as a learning experience! Size: 3.4cm Images in their natural sizes (Not compressed): https://imgur.com/a/8c3o4Jd
  15. Phevo's prep thread

    A year and some ago I bought a Krantz W 224 airscribe to start doing some mechanical preparation and promised to do a prep thread once I got started. Prior to this type of prep I have done a lot of silicone casting (which I might make a separate thread for) and on softer matrix used a mix of dental picks/tooth brushes. I have had several different setups over the past year, and the past 2 months or so can be seen on the following picture After spending a tedious amount of time with the rough matrix removal I decided to add a Cp9361 airscribe, which has sped things up a lot.
  16. My biggest Tumido crab yet!

    Well I started my next project tonight, and compared to the last one, this one is so much fun (so far ). The rock is softer and it also peels off the shell beautifully. Things are going to get a bit more complicated I can see already as there is a thick layer of powdery calcite around the edges. I originally thought it was shell and I’d stripped off the shell the whole time But I checked with the scope and it’s calcite. Some before pictures. The concretion is 24 cm (9.5 inches) wide. The claws were already exposed like this, I found it wedged in between 2 rocks facing me like this! The big claw exposed section is 8 cm (3 inches) long, so the big claw will be at least 16 cm (6 inches long)!

    Hi, Another newbie here requesting help with ID. Found in Big Brook. Thanks
  18. Crabs?

    Hey, I was wondering what you guys thought of these crabs they’re listed on fb and I don’t really want them because they’re pricey but I want to warn people if they’re fake and to me they look carved! TIA!
  19. Hello all, I was fortunate enough to find a donation worthy specimen last May (2019) during a North Carolina Fossil Club trip to a local quarry. I picked this up while walking along a quarry road and immediately recognized it as being a crab carapace, but I did not know the significance until some members of the NCFC (including our own @sixgill pete) informed me that it was very likely a new species. They then introduced me to Trish Weaver, the collections manager of the NCFC, and I donated it to the museum. Fortunately, Trish and Alessandro Garassino let me contribute to the writing of the manuscript that describes the specimen and let me be a co-author. I am incredibly grateful to all of those people that made this discovery and subsequent publication possible. Common or Scientific Name: Matutites collinsi Geologic Formation or Geologic Age: Spring Garden Member of the Castle Hayne Formation (Middle Eocene Region the fossil was found: North Carolina, USA Museum or University that received the fossil: North Carolina Museum of Natural Sciences Link to Publication: https://www.schweizerbart.de/papers/njgpa/detail/296/93733/Matutites_collinsi_n_sp_Crustacea_Decapoda_Matutidae_from_the_Spring_Garden_Member_of_the_Castle_Hayne_Formation_in_North_Carolina_USA
  20. Crab claws or twigs or what?

    Hello all i keep finding these and hope they are crab claws or similar and hopefully not just something off a tree. I attached photos of four although I have a number more. At least I’m pretty sure you won’t say they’re concretions. Thank you in advance

  23. HI all! I found a new to me crab leg! At least I'm fairly sure it's a crab leg! But I have not seen one like this. It's from Canyon Lake area in the Lower Glen Rose formation. I've looked at some of the literature but am not seeing anything that looks similar. Any help would be appreciated!
  24. Hello, I d like to know if someone would trade unpreped crab nodules. I mostly have french trilobites to trade. Some echinoid also . Some albian minicrabs carapaces. I post those 2 first. Ill post more later . The roller is Colpocoryphe rouaulti, the other one is a small Ectillaenus giganteus. Regards
  25. This fossil was found on a Gold Coast beach in 2019. I'm thinking Pliocene as it's like most of my beach fossil finds. It's a curiosity as it has some crystals inside the carapace. Any thoughts on this? Thankyou!
