Additional Information
The Pioche Shale is an Early to Middle Cambrian Burgess shale-type Lagerstätte in Nevada that preserves arthropods and worms similar to the Burgess Shale. It spans the Early–Middle Cambrian boundary; fossils from the Early Cambrian are preserved in botryoidal hematite, whereas those from the Middle Cambrian are preserved in the more familiar carbon films, and very reminiscent of the Chengjiang County preservation.
In the Eureka area, the Pioche has a variable lithologic character which is most commonly a greenish or grey, calcareous or micaceous shale which may locally be reddish or brown in color with abundant trilobite parts throughout the formation.
Crassifimbra walcotti is a trilobite from a Low diversity assemblage of Pytchopariid trilobites from the Lower-Middle Cambrian Boundary Interval, Pioche Shale, Southeastern Nevada.
