This is a very interesting pair of spiny Devonian trilobites. These are Kettneraspis williamsi from the Haragan Formation of Oklahoma. This specimen was found in 2000 and prepared in the EXTINCTIONS Prep Lab. The prone Kettneraspis is complete and exhibits fine detail. It is the curled Kettneraspis that is the eye catcher! Its long spines are beautifully displayed, with one eye and one genal spine prepared free-standing. The dorsal side of the trilobite has been prepared out (see photo #2), but so has the ventral side (see photo #3)! Even the hypostoma (mouthplate) has been exposed! Both trilobites have great color and contrast and are well showcased on the sculpted plate of marlstone. This is a very cool pair of Kettneraspis trilobites captured together forever in very different poses!
A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
