Antarctaspis (meaning "Antarctica's shield") is an extinct monospecific genus of arthrodire placoderm fish which existed in Antarctica during the Givetian age of the Devonian period.[1] The type species Antarctaspis mcmurdoensis was described White in 1968, and is known from a partial head shield discovered in the Lashly Mountains of Antarctica. It is one of the more basal members of the order Arthrodira, closely related to Yujiangolepis, as shown in the cladogram below:[1]
