    Abstract

    Two new trilobites from the Lower Cambrian Emu Bay Shale Lagerstätte at Big Gully, Kangaroo Island, are described. Megapharanaspis nedini gen. et sp. Nov. is placed in the Megapharanaspidae, a new family of the Emuelloidea. Holyoakia simpsoni sp. Nov. represents the first occurrence of the genus outside Antarctica, providing futher confirmation of the close faunal affinity between Cambrian trilobite faunas from Australia and East Antarctica. New specimens of Redlichia takooensis are documented that provide new morphological information, including a description of the rostral plate and hypostome.
