Click on images to enlarge, found in Benton county, Arkansas, Boone limestone formation
Again, the soft, porous limestone that is generally colored the same as red clay. Only this find was made in a lighter colored section of the rock that had hardened.
Trilobites are about as common in Benton county, Arkansas as speeding Buicks in Bella Vista. When you see one, you sit up and take notice.
I've been fossil hunting pretty hard for the last couple of months, and I've found one weathered cast on the exterior of a rock, and two posterior halves inside rocks I had cleaved open.
I found this specimen about two hours ago. It was an exciting moment, like having a Buick with a handicapped license plate blast around you doing 75! More pics in the article.
This was all of the intact cast that survived when the rock was cleaved open.
Here's the trilly with the matrix cleared away. There was a fragile razor-thin edge on the shell which unfortunately broke free during the clearing process. I cemented it back in place.
Nice trilly tail, a thrill to find!
