Objectif(s): The Early Cambrian is an important time in Earth history for it records the widespread radiation of animals during significant climatic, sea level, and tectonic changes. This project will be a stratigraphic, geochemical, and paleontological study of highly fossiliferous late Early Cambrian rocks in the Selwyn Basin, Mackenzie Mountains, NWT. This remote field area is an important location because it preserves shallow water carbonates and basinal equivalents which will make it possible to evaluate the nature and frequency of sea level and climate changes through sequence stratigraphy and chemostratigraphy. The researcher team will then use evoluationary studies of trilobites to consider how sea level, climate, and tetonic changes effected evolutionary patterns during this critical interval in Earth history.
