1.65" Rare, Spiny Ceratonurus Trilobite - Black Cat Mountain

This is a large example of one of the most sought after and rare trilobites to come out of the Haragan Formation of Oklahoma. These delicately spined Odontopleurids are considerably more rare the even the Dicranurus from this formation.

This specimen is fairly large for the species at 1.65" long and has elegantly flowing spines with the "horns" prepared free standing. It's light, caramel colored shell contrasts well with the limestone matrix that it is centered on.
