Weeksina unispina TrilobiteDescription: This plaque displays a rarely-seen example of a trilobite of the Order Ptychopariida, known as Weeksina unispina. It is easy to see where the genus derives its name. They possess a single spine on the 7th axial lobe, the source of the name of the genus. Few of the small trilobites are ever offered, with this one a fine, well-preserved example of the taxon.
