Yokoaspis sp.


Yokoaspis

Name: Yokoaspis sp.
Trilobite Order Ptychopariida, Suborder Ptychopariina, Superfamily Ptychoparioidea, Family Ptychopariidae
Locality: Pend Oreille County, Washington
Stratigraphy: Middle Cambrian, Metaline Limestone
Remarks: During the last few years a whole host of new species have been discovered in the Metaline Formation. This species was first considered an unidentified kochaspid when found by David Morgan's son, Sterling, in the Metaline Formation of Washington State. Sterling is a really great trilobite hunter and has been known to spot complete trilobites from the window of a moving truck. The trilobite has 31-32 segments and its presence may indicate that the Metaline Fm. is slightly older than previously thought. It may constrain the unit to the lowermost Middle Cambrian Delamaran Stage.
