Ill post more later . The roller is Colpocoryphe rouaulti, the other one is a small Ectillaenus giganteus. Regards

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!

guess what I found another brachiopod fossil today in the creek
matthew textor posted a topic in Fossil Hunting Trips
Hi everyone this is matt again guess what today I found another nice brachiopod fossil in the creek this time it is a big one here is a photo -
Good afternoon folks. I have a crab (Zanthopsis dufouri) from Spain that I've been prepping/detailing and came across something in it's claw. I am wondering if anyone can tell me if it was the crab's last meal or something I should remove? The crab still has one eye and one antenna so I'm thinking it's possible it could have been eating when it was covered. Comments are appreciated.

So I have been sorting, cleaning, high-grading and cataloging while stuck at home. I have been concentrating on material from the Walnut Formation of central Texas. The Walnut is the lowest formation of the Fredericksburg Group (Albian). Lower Cretaceous or if you're old school Comanchean. I have fossils from the west side of Austin all the way north to near Gatesville, TX. There are numerous members but the main ones I have collected from are the Bee Cave and Keys Valley Members. The Bee Cave mostly near Austin and the Keys Valley further north. This little crab was found in between near Georgetown, TX in the Keys Valley Marl Member almost seven years ago while collecting with JohnJ. This site produced another really cool new crab: Cenomanocarcinus cookseyi (Osso, et al., 2015) named for Bob Cooksey, one of our fellow FF members. Bob and JohnJ made sure that awesome specimen got into the right hands and was described. Kudos to both Bob and John! But I digress... I had found this specimen and it was mostly buried under matrix (oops no pre-prep pic) but enough was showing to tell me there was something worth while to be exposed. And at the time I thought it would prove to be another C. cookseyi. Well as I slowly picked away at it I realized it was something different. The specimen isn't perfect. The rostrum and orbits are gone as far as I can tell and there is some compression on the left side. But otherwise it is in pretty good shape. Please take a look and let me know if you might know what genera or species it is. The closest thing I have found is Aetocarcinus muricatus Schweitzzer et al., 2016, which is known from the Upper Glen Rose Formation (a tad older...) But there are a bunch of species shared between both formations.

Guys, I’m not sure what to do with this or about this, other than just keep it. I have since collected quite a few of this same specimen, all high-detail, but none that capture the full body like this. What would YOU do?

So-this collected yesterday in the Kansas City area again, but not sure what "layer" as the road cut was a jumble of mixed rock. My first thought was sea urchin spine, but I see only one row of spines, similar to what you see on many crustaceans; even though it is half-buried I thought sea urchin spines had generalized "points"?.... thanks again for all your patience reviewing these!

I just finished prepping this fossil crab, a tumidocarcinus giganteus I found here in New Zealand. Still using the one air scribe while I save up for a microjack I tried my hand at prepping both side this time, man that ventral takes ages to do!

I searched a new stream outside of the normal haunts and found some oddly packed matrix orange brown and granular in coloring, where I found some gastropods I posted last week. This time, I found scattered orange flat pieces that looked like crab arms and when I broke one chunk of matrix open, the flat piece was accompanied by this bottom portion of claw. Anyone have any idea what species this may be? Ghost shrimp? It wasn't in the usual NJ Cretaceous streams so I am not sure what formation it might have been in. @The Jersey Devil (Sorry for some images did the best I could with focus on such small stuff)

Hello, Went fossil hunting in a famous Swiss Jurassic Location, the quarry of Liesberg. While cracking some rocks found what seems to be a crab claw. Can anyone help me identifying it? I was not aware such fossils could be found there, is it common or rather rare? Thank you! Cheers, Romain

Hi everyone I've made a time-lapse of my prep of a recent crab I found here in New Zealand. It's one of the Tumidocarcinus Giganteus ones. I don't have a scribe for the fine detail yet, but got quite a bit of it exposed. Hope you enjoy it

Hello. I acquired a crab fossil (Harpactocarcinus punctulatus, Eocene, Italy). The fossil still has a whitish matrix patina that covers the back of the exoskeleton (and other parts). I think it's possible to carry out further preparation of the fossil to highlight the structures of the back - I have no experience in this regard but I am curious to know if it is possible (and/or advisable) to prepare the fossil with simple mechanical (or chemical) methods, since I don't have a sand blaster system. I attach 3 images of the fossil. Thanks in advance, Fabio

Myrtle Beach find. Thoughts? Haven't found one of these before, at least not fossilized. Looks like little white crab claws I've picked up from time to time.... It's hollow.

I am going to take my 9 years old son to California in mid February for a week. We plan to collect shark tooth at Ernst Quarries and we also want to collect other fossils along the coast from San Francisco to LA. I did many research and found a few sites that we really want to go. Bean Creek at Scotts Valley for sand dollar, Capitola Beach for shells and maybe whale bone, Carmel valley for crab, and Jalama Beach for fish. I did more research and found out that the Bean Creek location is off limit now. I would like to ask if the other places still ok. We will fly to LA and drive up north to San Francisco so I don't want to have to drive all the way up just to know that we can't collect the fossil. Also if you have other locations that you can share, it is greatly appreciated. Thank you so much and I can't wait still February.

Hi everyone, so I have just gotten into fossil prepping and I'm practicing on some crabs that have some damage to them. Learning so much with each hour I spend! I made a time-lapse of the most recent one: https://youtu.be/kH33t4NklYk?t=675 (short version) https://www.youtube.com/watch?v=STw905QB570 (long version) It's still quite rough at the end, I need to smooth the rock out and I haven't tried to get into the really tight spots with my current tool - waiting to get something like a micro-jack.

A couple of hours in on our fossil hunt at Glen Afric, I spotted another crab fossil! This had now been our 3rd crab of the day. We have not found a similar crab to this one. Any ideas or thoughts on why the colour is so strange?

How big do fossil crabs get? Some large Tumidos
Doctor Mud posted a topic in General Fossil Discussion
Having found my biggest crab yet, I was very curious about how big the Tumidocarcinus giganteus gets. It sure lives up to the species name giganteus! @Dave (POM) Allen has found a massive claw, the biggest I’ve seen. Could be from a huge crab too, but I’ve seen some really massive claws that are way out of proportion with the crab. I’ll have to dig out the photo from my computer when I’m home, but I have an amazing example of this. The Canterbury museum has the biggest specimen - complete crab I’ve seen There it is near some normal sized (but still much larger than Washington) crabs. I didn’t have any measurements on it, but when I visited Al Mannering to do some prep he had a replica and I asked if I could take some photos for reference. Check it out! Andrew Fear who is another regular Tumido collector has found this guy Don’t have any scale on it, but it is impressive! Love to see any other large examples, or even the other end of the spectrum like @RJB tiny Tim the Tumido- 18 replies

Hey. So today on a whim I decided to give fossil hunting a go. Took my family to the beach at Glenafrik farm, about an hour north of Christchurch, New Zealand. About 30 minutes in I stumbled across this beauty (beginners luck huh). Now I’m wondering, what am I supposed to do to clean/preserve it? Also, my wife found what we think could potentially be a fossilised log? It is very heavy and to our untrained eyes, looks like a log with bark around it. It was quite different from all the other rocks in the area. What do you more knowledgeable guys and girls think? Again, any tips or thoughts on cleaning/identifying it?

Hello I found this along a small spring fed stream in Gonzales county, Texas. This area has produced plenty of ice age fossils and was home to numerous boiling mud pits which ended in the late 70s due to oil production; not sure how relevant that it haha

I’ve been in New Zealand for over a month and spent a lot of time on the coast famous for the big Tumidocarcinus crab concretions. Unfortunately my trip was mainly to visit my father who was ill and he passed away while I was here. Time on the beach has been a good distraction and helps to start the healing process. You might be surprised that I usually have the beach to myself and the solitude and sounds, sites and smells of the coast are a comfort. In terms of fossils it was my best trip yet, but this came from lots and lots of walking, boulder hopping, and early starts. Sorry pictures are large files since I’m doing this from my phone. So spread out in many posts. Day 1, was exploring new sections of coast, clambering over rocks the size of a bus with razor sharp shells. Found some nice concretions, but they were empty

Ive been working on a most wonderful crab concretion these last few weeks and finally got to the grinding stage to smooth out the tool marks. While grinding at times I would realize a bad smell? About the 3rd or 4th time I smelled this smell I began to wonder what was going on? and no, I wasn't passing gas, (just to stop any of you funny business type fellows). My guess is sulpher? I noticed when i was prepping this crab that its got a bit of pyrite in it so the rock must too? Right? Has anyone ever experienced this? Can grinding on a rock with sulpher in it produce a bad smell? Its not a big deal but just wondering. RB
