The fossils found in this period are: Quaternary Period - Pecten gibbus and Neptunea tabulata Tertiary Period - Calyptraphorus velatus and Venericardia planicosta Mesozoic Era This era is considered as the age of medieval life. About half of the Paleozoic fossils are trilobites. The interior of the shell is white, often with some beige coloration on the "ears" and top edge.
