NOTE: These trilobite faunal lists were compiled by Caleb Scheer (now deceased) and are on his Midwestpaleo.com website, here:
http://www.midwestpaleo.com/Fauna/Fauna.htm
Since Caleb has passed, I do not know how long the site will be up. He was the foremost expert here on trilobites. His passing is a tragic loss to the fossil community.
