This is a very nice spiny trilobite, a Kettneraspis williamsi, is a member of the Order Lichida. The free standing dramatically displayed genal spines are not often preserved intact. One of the reasons for the fine preservation is the fact that this trilobite was collected and prepared last century by Bob Carroll, a world-renowned preparator of Oklahoma Devonian trilobites. A small phenomenal collection piece.
