MB Posted May 23, 2017 Author Share Posted May 23, 2017 You can not despise anything, even the most miserable piece of rock, look friends, last week, browsing in old boxes, found a very small chunk of tufo volcanico from the Eocene of Vicenza region (Italy), that I got from a good friend years ago... with something white looking out... a very small hermit crab chela, but a big surprise, one of the ones that just described a friend of mine in a superb article : Lessinipagurus planus De Angeli & Caporiondo, 2017. Obviously, being a hermit crab, you can't expect to find carapace (they have not) and usually neither legs, only chelae remains, but they are amazing, isn't? 3 http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...

Doctor Mud Posted June 26, 2017 Share Posted June 26, 2017 I have a question fellow crab preppers. Ive noticed a few Tumidos that are 3D prepped (top and some underside) for sale with their claws positioned nicely away from the front of the carapace and angled away from the front. I haven't seen this preservation style yet with Tumidos not saying it couldn't happen but.... Has anybody heard of the practice of carefully disarticulating the claws and repositioning in a more asthetic or nice looking position? i guess it could be done but you would have to be careful with the tips of the pincers and making the join look natural would be tricky. Ive seen other species like this that I have wondered about too. here is an example: To me the positioning looks unnatural for a Tumido. Link to comment Share on other sites More sharing options...
RJB Posted June 26, 2017 Share Posted June 26, 2017 Ive prepped out quite a few Tumido's over the years and have never ran into one like that. I would assume that the claws have been repositioned? RB Link to comment Share on other sites More sharing options...
bruce Posted June 26, 2017 Share Posted June 26, 2017 I’ve never prepped a Tumidos, but have done plenty of Pulalius crabs from NW OR & WA and although the smaller ones often seem to have their claws tucked in--they can be found in any position, probably depending on if they were molts or how they were buried. I’m always looking for ones with the claws outstretched, as its makes a more challenging and fun prep job and the results are interesting. I don’t think it would be easy to stage or maneuver them, as they would be hard to re-attach ( I use use cyranoacrylate and one needs a clean, snug attachment point). Here is a group of mine, reaching out—all in the same position when uncovered. 2 Link to comment Share on other sites More sharing options...

MB Posted June 26, 2017 Author Share Posted June 26, 2017 Not usual in Tumidocarcinus, but who knows... the only way to know is examining the merus and carpus and check if they are, like you said, disarticulated and then repositioned as it is done in many commercial Italian crabs, for example most of Harpactocarcinus and Harpactoxanthopsis you see everywhere. 1 http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...

I've seen it on one other, but it had a huuuuge dominant claw. still some nice prep work if there has been some fiddling.

Thanks for the nice images Bruce. it does seem to be more common for this species of crab and certainly makes for a dramatic and eye catching piece if you have the skill, patience and courage to prep it that way.

I don't think in contraction after death but in a defensive posture. Another thing would be if they were in a dry environment, but they are in the water. Anyway I'm with RB, but this one could be an exception, I don't know. http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...

Doctor Mud Posted July 16, 2017 Share Posted July 16, 2017 Our cat "Mr Ron" tends to kindly demonstrate the usual preservation for Tumidos. Both claws "paws" tucked under. (A common winter morning preservation for Mr Ron) Big (usually right claw/paw) extended left claw/paw (smaller) tucked under or at least close to the front. (The heater is on now!) a very uncommon position for fossil tumidos..... More common for Mr Ron. Link to comment Share on other sites More sharing options...

He is not named in honour of one of our resident crabmeisters @RJB This did cause some confusion when I was swapping some fossils with RJB (Ron) with my wife though. Me "I'm getting fossils from Ron" Her "You are getting fossils from Ron? What?" Me "Yes, we are trading" Her "??????" Me "Fossil Forum Ron, not Mr Ron!" Being a ginger Tom he is named after a famous ginger or redhead character Ron Weasley from Harry Potter. It fits his personality. Except we add the Mr on the front cause that just seemed to fit him as well. He has a certain sense of authority and charisma that called for the Mr. Link to comment Share on other sites More sharing options...
