Etymology

The generic name Irizaripteris (Irizar, plus pteris = fern) is proposed in honor of Julián Irizar Echeverría, captain of the Argentine Navy's schooner, ARA Uruguay, who in November 1903 rescued shipwrecked members of the Swedish Antarctic expedition, whose crew collected the fossil specimens described by Dusén (1908).
