jgcox Posted April 14, 2014 Share Posted April 14, 2014 A friend in the Dry Dredgers gave me several flats of matrix he collected 10 years ago at Mt. Orab. He said I could use the matrix to practice prepping. So I found this Flexicalymene meeki, he is missing his phygidium but still a great display.

Polioliolio Posted May 2, 2014 Share Posted May 2, 2014 Looks great! I hope to find and prepare similar looking fossils someday. Link to comment Share on other sites More sharing options...

MarleysGh0st Posted May 2, 2014 Share Posted May 2, 2014 would love to have been able to collect there just once! and of course score a 6 inch prone isotelus... You wouldn't be satisfied with an enrolled specimen? I sure was, when I was there on Sunday with the Penn Dixie field trip! Dan Cooper will be including the specimen in a growth sequence destined for the Smithsonian, so at the moment I don't even have a photo to show off, but my name will listed as the collector when it gets its NMNH number!

DLB Posted May 4, 2014 Share Posted May 4, 2014 I was wanting to know how to prep these trilobites. Do u use a pick or something more aggressive like a air scribe? I just came across a few and have never prepped one before. Any help would be great thanks in advance . Link to comment Share on other sites More sharing options...
jgcox Posted May 4, 2014 Author Share Posted May 4, 2014 DLB I use an air scribe or an electric engraver, then I use a pin vise with a needle tip to soften or remove matrix from between the thorax segments. I then use a mini sand blaster with dolomite as the blast media to clean off any hard to remove matrix. Hope this helps. Link to comment Share on other sites More sharing options...
DLB Posted May 6, 2014 Share Posted May 6, 2014 Thanks I think it will help me I just need some practice Link to comment Share on other sites More sharing options...
jgcox Posted May 6, 2014 Author Share Posted May 6, 2014 Practice on some broken specimens that way if you break a piece and you will then its not as bad as breaking a nice specimen. and practice on different matrixes also. Best of luck and practice practice and practice. Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted May 6, 2014 Share Posted May 6, 2014 enrolled works! i've found only one small isotelus, a perfect little enrolled "kermit the frog" back in 1980.

Dan Cooper will be including the specimen in a growth sequence destined for the Smithsonian, so at the moment I don't even have a photo to show off, but my name will listed as the collector when it gets its NMNH number!
