Description
Bolaspidella is a small species, with most individuals measuring well under one centimeter. This specimen measures 9 mm and is perfect, sporting axial spines and a pustulose exoskeleton. The spines are likely to protect against predation. Situated on light colored matrix, the reddish-orange trilobite is centered with bits of red trilobites on the plate as well.
