Cyphaspis carrolli Oklahoma TrilobiteDescription: Well-preserved example of a member of the Order Proetida, Family Aulacopleuridae,. One of the reasons for the fine preservation is the fact that this trilobite was prepared by Bob Carroll, a world-renowned preparator of Oklahoma Devonian trilobites. Bob has worked on Oklahoma trilobites for some 25 years now (see photo of bottom of piece). During that time he has prepared countless specimens, and has given away scientifically significant examples to research institutions. He was honored in 1997 by having this diminutive trilobite named for him. I have known Bob since my first visit to Tucson in 2001. The first trilobite of Bob’s in my collection is an example of this trilobite which he autographed for me. To have a trilobite, collected by Bob, prepared by Bob, and signed by Bob is most significant to me, a symbol of our long-standing friendship.
