Abstract:Ivanovia triassica is a new species of calcified Codiaceae from Triassic rocks of the Yukon Stikine Terrane in Canada. The genus was known previously only from the late Paleozoic. Stalked outgrowths of the thalli are interpreted as oogonia and dome-shaped outpocketings as male gametangia. These represent the first sexual reproductive structures observed in Ivanovia . Sectional views of the thalli indicate the species was cyathiform and that the inner and outer cortices of the membranes comprising the thallus were dimorphic.
