Abstract

A new asterolepidoid antiarch is described from sediments of probable Late Devonian (Frasnian) age in the Boyd Volcanic Complex. on the south coast of New South Wales. It occurs as a rare element in an assumed freshwater assemblage wi th abundant Bothriolepis and Phyllolepis, and less common rhipidistian, acanthodian, and possible onychodontid remains. Pambulaspis cobandrahensis gen. et sp. nov. resembles Remigolepis in possessing separate posterior dorsolateral and lateral plates and a prominent postorbital crista, and resembles Asterolepis in having an elongate postorbital process and prominent subobstantic area, and lacking the posterior oblique pit-line groove in the adult. It differs from both in that the posterior dorsolateral completely overlaps the anterior median dorsal, and the lateral line canal crosses the posterior lateral plate instead of the posterior dorsolateral. The preorbital region of the skull , certain plates of the trunk, and the basic structure of the pectoral fin are not known. It is suggested that Pambulaspis is closely related to Asterolepis and Remigo/epis, and may be a sister taxon to the latter. The most recent common ancestor of these genera must have been Eifelian or older.
