A Guide to the Orders of Trilobites - A site devoted to understanding trilobites. In this page I want to try to tell a little bit about the world of the trilobites and how it relates to what we find today. There are some other very good websites and I will tell you about them. In Western Nevada - A virtual field trip to a classic Early Cambrian trilobite locality north of Death Valley National Park. To The Nopah Range, California - A detailed virtual field trip to a productive Early Cambrian trilobite locality southeast of Death Valley National Park.
Cambrian deposits are spotty and unfossiliferous.
The most diverse fossil fauna is in the Ordovician, Silurian and Devonian periods.
