Middle Cambrian

Wheeler Shale

Millard County, UT, USA

14mm negative arthropod on 75mm slab

Arthropod,

This specimen has the segmented body of an arthropod.  It does not appear to be a trilobite nor aglaspid nor a member of another class of that phylum of that time.  It’s certainly a conversation piece for the advanced collector – a shadow of a creature from the awakening of complex life on earth.
