Submitted on 2010-11-04 by John Topor
Location (approximate): Thedford, Lambton, ON
Strat unit: Widder formation
Submitter notes: It is not uncommon for Greenops specimens to have their pygidium tucked under. A little extra cleaning will expose what first appears to be a tail-less specimen. This trilobite is 21mm wide and is approximately 34mm long if you count the enrolled tail.
