Fortune Head
Fortune Head records the beginning of a period of increasing biological diversity known as the "Cambrian explosion". It has a number of other Cambrian and Precambrian fossils, including early shell fossils, vendotaenid algae, soft-bodied megafossils, and microfossils. Below Treptichnus, the stratotype at Fortune Head includes traces of the arthropod Monomorphichnus. More complex fossils appear later.
