IonRocks Posted September 29, 2015 Share Posted September 29, 2015 Pinnixa galliheri- Miocene I just purchased this crab and noticed that it appears that it isn't fully uncovered, so two questions, is this more crab? And can anyone see a reason for not preparing this area of the crab? Link to comment Share on other sites More sharing options...
caldigger Posted September 29, 2015 Share Posted September 29, 2015 What part are you referring to? Those crabs are basically like a carbon film, I don't think there is anything more to uncover. You are not going to get a hard carapace like the crab concretions of the northern coast. Link to comment Share on other sites More sharing options...
PFOOLEY Posted September 29, 2015 Share Posted September 29, 2015 There is more. Revealing it will be tricky. "I am glad I shall never be young without wild country to be young in.

IonRocks Posted September 29, 2015 Author Share Posted September 29, 2015 Yes I understand the non-3d part... To the right of the crab there is rock above the layer of the crab, hiding that layer. On the side you can see the crab continue under the rock? Rather difficult to explain so I'll mark up my image The area circled is covered by rock from above Link to comment Share on other sites More sharing options...
IonRocks Posted September 29, 2015 Author Share Posted September 29, 2015 Yeah I'm not talented enough to do any sort of prepping on something this thin. More just a curiosity, and maybe one day I'll be skilled enough. Maybe one day I'll have someone else do it. But next question, why would one leave it alone? It's sorta obvious I'd assume especially to someone who has done a lot of these Link to comment Share on other sites More sharing options...

jpc Posted September 29, 2015 Share Posted September 29, 2015 I think it can be done, but it should not be your first or second prep project. It needs a binocular microscope to do it well. Link to comment Share on other sites More sharing options...

IonRocks Posted September 30, 2015 Author Share Posted September 30, 2015 So another question, what would part of the crab would this be? More legs? More of the body (Sorry guys I am no crab specialist.. Only trilobites terms are well known to me) it appears that the body may continue on. I'm sure it's hard/impossible to tell without actually having it dug out but an logical speculation is appreciated Link to comment Share on other sites More sharing options...

IonRocks Posted September 30, 2015 Author Share Posted September 30, 2015 I would be so glad to have another pincher Link to comment Share on other sites More sharing options...
Auspex Posted September 30, 2015 Share Posted September 30, 2015 Study the broken edge for clues as to how far the crab extends. If you decide to work on removing the covering matrix, start well outside that point, and work in.

Doctor Mud Posted September 30, 2015 Share Posted September 30, 2015 I'm guessing that this fossil was exposed in one go by splitting the rock. Perhaps a decision was made not to go further as there isn't too much left to uncover (the reward is fairly low) and there is a fracture running right through the crab (the risk is high). I think Fossil Dude is on the money and you have the front of the crab she'll still covered. Looks like you have half a crab roughly in total so you wouldn't get another pincer.

IonRocks Posted September 30, 2015 Author Share Posted September 30, 2015 Well I know that the crack was actually repaired. The crab seems to go another third of the way (so about a third is covered ya' know) I also know that for now I definitely won't do any work on it. Maybe someday. But I'm gonna get some practice in before I try harder stuff Link to comment Share on other sites More sharing options...
ZiggieCie Posted September 30, 2015 Share Posted September 30, 2015 I would leave him alone. 95% is showing and looks very nice. Why take a chance. Link to comment Share on other sites More sharing options...
AncientEarth Posted October 8, 2015 Share Posted October 8, 2015 If you are confident enough, prep it. They prep a lot easier than you'd think. Yes thin layers but they split and flake nicely. This looks like a crab fossil I collected from the central coast of California. Did you get this at the Denver show by any chance? Just collected a few dozen of these yesterday evening. It is the Monterey Formation, but from San Luis Obispo County, not the typical locality from near Monterey, CA. Link to comment Share on other sites More sharing options...
IonRocks Posted October 27, 2015 Author Share Posted October 27, 2015 I went a head and dos actually, disregarding the majority of everyone's advice (started near the crab etc) (Also sorry I didn't see your post until now AncientEarth) No I ordered it online (sounds like fossil air uh) I also just misread the card it came with on the locality I didn't see any at the Denver show, I just saw a lot of fake stuff I only prepped it because I figured that after it cracked (there was already a crack that didn't go all the way through, i dropped it) I couldn't mess it up anymore. Otherwise I may not have. So yeah, there is still a good bit more but I haven't gotten around to it. It does appear that another appendage is preserved (but pictures don't do that observation much) I did it with dental tools, a brush and plan to smooth it out with a diamond pick thing (idk) Link to comment Share on other sites More sharing options...
