Hello, here is a "Big for this species" 100% natural Elrathia Kingi Trilobite fossil in its Wheeler Shale Formation matrix! This fossil plate was quarried in Millard County, Utah on the House Range.
This fossil dates from the Middle Cambrian Period, 541 to 485 Million years or....a Crazy Half BILLION years ago!
The Trilobite fossil measures around 1 7/16" or 3.57cm at its biggest or from its Cephalon... head to the Pygidium.. tail!
Please note that it is WAY nicer in person as it is difficult to get all of the true colors and detail to show up in the photos.
