Bolaspidella drumensisDescription: Coming from the Cambrian Wheeler Formation deposits of Millard County, Utah this is a fine example of a trilobite that is a member of the genus Bolaspidella, of which several species are found in the region. This species derives its name from the location in which it is found, the Drum Mountains. This one is unusual in that it comes from the upper part of the Wheeler Formation, thereby making it older than most specimens seen.
