is 42 mm long
Jangle Limestone, Carrara Formation, “Johnny site”, Pahrump,
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.
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.
