Many of the fossils collected from the fossil rich beaches of West Dorset come from the rocks of the Lower Lias. To assist with the proper naming of horizons please refer to the naming scheme that is used in the Palaeontological Association field guide: Fossils from the Lower Lias of the Dorset Coast.
