Coco Posted June 18, 2011 Share Posted June 18, 2011 Hi Nando, I am not able to help you, but in the urgency, use of the repulsive with cat ! Anhuta just said me : "tell him to send it to me, I am going to try to prep it. If it is beautiful, I keep it. If it is not beautiful, I send back to him".

Terry Dactyll Posted June 18, 2011 Share Posted June 18, 2011 Theres plenty crab enthusiasts on here with many of them preppers... maybe someone will offer to do it for you Cheers Steve... And Welcome if your a New Member... Link to comment Share on other sites More sharing options...
Nandomas Posted June 18, 2011 Author Share Posted June 18, 2011 (edited) Theres plenty crab enthusiasts on here with many of them preppers... maybe someone will offer to do it for you Thanks, I wanted a ball like this just to try and to learn how to do. The problem with balls is that they are round :wacko: Where to begin? Someone told me to roll the concretion on the floor and the down side is the upper part of the crab, but I think this is a metropolitan legend p.s. Goooooooodmorning Tracer and Anhuta :P Nice too see your ideas are so fresh in the morning :D Edited June 18, 2011 by Nandomas Erosion... will be my epitaph! http://www.paleonature.org/ https://fossilnews.org/ Link to comment Share on other sites More sharing options...
tracer Posted June 18, 2011 Share Posted June 18, 2011 i never base any of my decisions on metropolitan legends. and i think the thickness of the concretion as it formed around the nucleus (if any) would determine whether the external shape of the concretion were to any extent affected by the shape of the nucleus. obviously one side is flatter than the other, so if you believe there is a crab inside, and that the crab determined the outer shape of the concretion, then the answer is clear. but if, on the other hand, you believe that a crab would mess with you by dying upside down in a concretion whose external shape was determined by geology, then you're being set up for heartbreak. the safest thing to do would be to prep half of the concretion from the side, and then you're bound to expose half of the crab that you can display either upside down or rightside up. if there's a crab in it. some concretions form around other concretions, like matryoshka dolls. i think. man, what if you keep prepping through concretion after concretion and just find an ostracod in the center? some things aren't as they seem Link to comment Share on other sites More sharing options...

Auspex Posted June 18, 2011 Share Posted June 18, 2011 Our super-preppers of crab nodules sometimes break the concretions open to discover the orientation of the crab, then glue them back together and scribe down to them.

Diplotomodon Posted June 18, 2011 Share Posted June 18, 2011 that's considered cheating on 6 of the 8 known continents I wouldn't say cheating...more like creative integrity. Although if you break it open, what if you break open the crab as well? What a wonderful menagerie! Who would believe that such as register lay buried in the strata? To open the leaves, to unroll the papyrus, has been an intensely interesting though difficult work, having all the excitement and marvelous development of a romance. And yet the volume is only partly read. Many a new page I fancy will yet be opened. -- Edward Hitchcock, 1858 Formerly known on the forum as Crimsonraptor @Diplotomodon on Twitter Link to comment Share on other sites More sharing options...
Auspex Posted June 18, 2011 Share Posted June 18, 2011 ...if you break it open, what if you break open the crab as well? That is exactly what happens (to a greater or lesser degree). Gluing it back together after noting the orientation leaves it almost as good as new.

Nandomas Posted June 18, 2011 Author Share Posted June 18, 2011 Thanks everyone for the info. What about the concretion hardness? Thanks Erosion... will be my epitaph! http://www.paleonature.org/ https://fossilnews.org/ Link to comment Share on other sites More sharing options...
