The Weeks Formation is a geologic formation in Utah. It preserves fossils dating back to the Cambrian period and more specifically the Guzhangian stage. Its upper part has yielded a diverse fauna dominated by trilobites and brachiopods, but also comprising various soft-bodied organisms, such as Falcatamacaris . [1] As such, it is regarded as a Konservat-Lagerstätte.
