Nice .8 inch Oklahoma Kettneraspis Trilobite
Here is a nice example of the spiny Lichid trilobite, Kettneraspis williamsi from the Haragan Formation of Oklahoma. It's got long flowing spines, shows great surface detail and has a beautiful carmel colored shell that contrast beautifully against the creme colored marlstone matrix. It was microscopically prepared under microscope using air abrasives a process that would have taken 4-6 hours to complete.
