“Johnny” Spiny Albertella longwelli Trilobite

Description: Amongst the most collectable of Nevada trilobites are Albertella longwelli. They are dazzling in their spiny flamboyance. Long spines project from the cephalon, large macropleural 3rd segment thoratics and pygidium.

This trilobite comes from the famous “Johnny” site, outside of Pahrump, Nevada. Generally the Albertellas are one inch or smaller. This one, at 42 mm, is amongst the largest and most exquisitely preserved ever collected from this site. A second very petite Albertella is located off of the right top portion of the genal spine.
