This is a great multiple specimen of different Lower Devonian trilobites from Oklahoma. There are two Kettneraspis williamsi and a Huntonia oklahomae tail preserved on the plate. It is very unusual to find trilobites in such close proximity to each other, from any locality, let alone this famous site. The spiny Kettneraspis williamsi trilobites are wonderfully articulated and extremely detailed. The "fringes" on the free cheeks are readily apparent. The long genal spines and pleural spines are beautifully exhibited. The Huntonia pygidium is quite large for this type - it is larger than both Kettneraspis combined. The fossil arthropods have great color and contrast and display well on the large plate. And there is NO COMPOSITING of the fossils whatsoever - it is fully natural! This is a very collectible multiple trilobite specimen from the Devonian of Oklahoma.
A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
