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.

You wouldn't be satisfied with an enrolled specimen? I sure was, when I was there on Sunday with the Penn Dixie field trip! :D

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! B)

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 .

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.

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.

enrolled works! i've found only one small isotelus, a perfect little enrolled "kermit the frog" back in 1980.
