Description

A Certificate of Authenticity will accompany this specimen.
This is a fossil Sea Urchin from the Mississippian, a period of time ranging from 363 million to 323 million years ago. Long before the first dinosaurs.
It is Archaeocidaris illinoisensis, and it is about 1.7 inches. Found in the St. Louis Limestone, St. Louis, Missouri.  The rock it is on is about 2.6 inches.
Sea urchins are a type of echinoderm, with some species still alive today.
We are happy to enclose a COA (Certificate of Authenticity).
Some words of caution about COA’s: Do not let them become a substitute for learning about the specimens. We have been working with fossils and minerals for many years, and we have seen hundreds of very nice-looking COA’s, some that are wrong, mis-describing a specimen. In addition, the person selling the item is often the one who writes the COA (potential conflict of interest). Finally, a COA without a photo of the exact item described, as part of that COA, is worthless, as it can later be placed next to any other fossil or mineral.
We suggest that instead of relying on a COA, that people read and study the subject.
