The Paleozoic (from 542 to 251 million years ago) was a time of extraordinary events and geologic upheaval such as the extraordinary radiation of life, extraterrestrial impacts and mass extinctions, all punctuated by both alpine and continental glaciations. The study proposes to collect proxy material (i.e. brachiopods and trilobites) and examine the geochemical evidence (trace and isotope chemistry) to characterize these events. Material for this project will come from two major sources, one being carbonates deposited on seamount Japan during the Paleozoic reflecting Panthalassic Ocean (precursor Pacific) oceanography and from large and continuous successions at the North American continental margin. The latter localities are unique and important in that the successions are sedimentologically & stratigraphically well defined in the context of Paleozoic biogeography.

古生代（从5.42亿年到2.51亿年前）是一个非常事件和地质剧变的时期，例如生命的非凡辐射，外星人的影响和大规模灭绝，所有这些都被高山和大陆冰川打断。该研究建议收集代用材料（即腕足动物和三叶虫），并检查地球化学证据（痕量和同位素化学），以描述这些事件。本项目的材料将来自两个主要来源，一个是反映泛海底海洋（前太平洋）海洋学的古生代期间沉积在日本海山上的碳酸盐，另一个是北美大陆边缘的大规模连续演替。后者的地点是独特的和重要的，因为层序是沉积学和地层学在古生代地层学的背景下很好地定义。
