Doctor Mud Posted November 18, 2014 Share Posted November 18, 2014 I knew it must be tricky if you couldn't figure it out straight away RB. Hope it works out. Look forward to seeing the finished product. Link to comment Share on other sites More sharing options...

crabfossilsteve Posted November 18, 2014 Share Posted November 18, 2014 Hey Ron Nice looking concretion there bud. I pretty much do the same thing as Bruce, except I use a diamond grinding wheel and grind a pit down in the middle section of the concretion just until I see a change in color of the carapace. Then use my tools to work out from there until I can determine if its dorsal or ventral. That way you haven't destroyed a bid section of the concretion and could flip it over and begin anew if you goofed. However, if you look at the cross section of the legs on the outside edge of the concretion, I think you can see that one surface is round and the other section is flat. I think you'll find that the rounded surface represents the dorsal and the flat is the ventral. Can you get a good close-up of the cross section of the legs? Check it out. 1 Link to comment Share on other sites More sharing options...
RJB Posted November 19, 2014 Share Posted November 19, 2014 Mr. Stevie boweeeevie. Ha! Hi steve. Hey, I now think your a miracle worker genus. I was wondering about those legs? You can barley see the legs, but my guess was just how its laying in the pic. The rounded part of the legs being upward. The rock was soooooo even that once I would guess what is what, I would then immediately start 2nd guessing myself and got myself very frustrated many times. Been a long time since ive learned something new. Thank you mr.steve. RB Link to comment Share on other sites More sharing options...

bruce Posted December 16, 2014 Share Posted December 16, 2014 If you find yourself with a hard-to-display fossil, there are museum display companies that offer a variety of sizes of pre-made stands for free-standing fossils, shells, and minerals. Here are two fossils I wanted to display in an upright setting—a fossilized cartilage shark vertebra and a partially eroded crab showing both the dorsal and ventral sides. Not wanting to spend a significant sum for a museum display stand, I decided to try to make my own. To make a cradle to hold the fossil you need 16 gauge floral stem wire which you can get from a craft store or floral shop. They come 16” long, a dozen to a pack for under $2. Take a needle nose pliers and experiment bending a continuous cradle to fit your fossil. If you make a mistake, you can adjust, straighten and rebend until you get it just right. You might want to sand the end where you begin your fossil-holding cradle, so it doesn’t scratch your fossil. Scrap pieces of 2 x 2’s or 2 x 4’s, or 4 x 4’s can be used for the base. Find the center of the block and drill a hole, the same diameter of the wire about 1” deep—be careful not to go all the way through. You will have extra wire left over, so cut it off long, so that you can position it in the block and gauge the proper height to esthetically display the fossil, and still trim a little off, if its too tall. The first cut I made was too short and looked squatty, so leave yourself plenty of wire to trim down the height until you find it where it looks best. I had some flat black water-based craft paint leftover, so I painted the block and wire with two coats—no need to buy expensive spray paint. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted December 16, 2014 Share Posted December 16, 2014 Good idea. I know a guy who makes little cradles for his tiny fossils out of paper clips. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
