Trilobite Protolenus densigranulatus, Middle Cambrian, Jbel Wawrmast Formation (Tissafinian Stage), Morocco.

Ones of this quality preservation are quite uncommon.
Trilobite Isoteloides flexus Millard County, Utah is famous for the quality, and quantity of its Middle to Upper Middle Cambrian period trilobites. The Ordovician period is also well known, but far fewer trilobites are known and available from these areas. The associates at Fossil Mall have recently leased the most famous and productive of the Ordovician quarry sites. We have named it the Pyramid Ridge Quarry.
