Location (approximate): Arkona, Lambton, ON

Strat unit: Widder formation

Submitter notes: Two Greenops widderensis on one plate. Both are complete but one has the head rolled under the body and is partly disarticulated. The largest has the complete tail on the reverse shown in another view in this group. The largest is 1.9 cm wide at the cheeks and would be about 3.5 cm or 1.4 inches long if laid flat. The disarticulate one is almost the same width but length is hard to measure.
