Rich mid-Cambrian trilobite faunas were recovered from limestone boulders in conglomerates that form the lowest exposures of the Cow Head Group (Shallow Bay Formation) near Broom Point in western Newfoundland. These boulders were derived from various shelf-edge and upper slope environments along the margin of Laurentia. Twenty-nine species representing twenty genera are described. Three trilobite biofacies are defined based on the abundance of the genera in separate boulders."
