This is a spectacular trilobite, it is one of the best and most detailed PERONOPSIS trilobites I have ever seen. The detail on this little bug – that is full grown) is spectacular. One can even see the little spines on the cephalon and pygidium. It is also one of the most well known and recognizable trilobites coming from the Wheeler Shale.
They are sometimes found in vast numbers in mass death assemblages. Here is a very nice trilobite from the Cambrian Period, the “Age of Trilobites”
Its distinct black color on a gray matrix makes the trilobite seem to jump off the shale rock matrix.
They lived, thrived, and became extinct MILLIONS of years before the age of dinosaurs!
Trilobites spanned a time that covered 5 geological periods spanning over 300 million years of Earth’s history
This Outstanding trilobite is 3/8 inches by 3/16 inch set on an irregular shaped matrix block that is 1 3/4 by 1.
A Classic trilobite from a classic location.
