Dear all, I need some help. I have four specimens of Laevicardium mortoni in my collection. The valves can come seperate from each other, and this becomes annoying when i'm trying to rearrange. I need a method to hold them together, but I don't want to glue, cause the interior is just as important as the exterior. I also need a method to hold together some Anamalocardia auberiana specimens. Thanks, James
