Trilobites of the Wheeler Formation
Phylum Arthropoda, Class Trilobita
Geologic Age: Middle Cambrian
Fossil Site: Upper Wheeler Formation, House Range, Millard County, Utah

Elrathia kingii: (Order Ptychopariida, , Family Alokistocaridae)
Bolaspidella housensis (Order Ptychopariida; Family Menomoniidae)
Peronopsis interstricta (Order Agnostida; Family Peronopsidae)
Asaphiscus wheeleri (Order Ptychopariida; Family Asaphiscidae)

The main reason that Western Fossils is headquartered in Utah is that Utah is America's most fossiliferous state. Nearly every geological age is represented, and the Cambrian period is particularly well represented. Trilobites are diverse and abundant, though few people realize the work required to collect and prepare them. The trilobites below are all from Western Fossils lease in the Wheeler formation which occurs in the House range just west of Delta, Utah, and were prepared by me in our lab.
