3.2" Huntonia Lingulifer (Rare Species) - Oklahoma
This is a rare, long-spined Huntonia lingulifer trilobite from the famous Black Cat Mountain in Oklahoma. Huntonia lingulifer is MUCH rarer than the other species of Huntonia in the same horizon at Black Cat Mountain. Less than one in ten of the Huntonia's found are lingulifer, so on average there may only be one or two good complete specimen found each year. One of the main characteristics that separate it from the other species of Huntonia at the locality is the much longer pygidial (tail) spine.
