Abstract

The new species Craticularia australis is a broad, conical, stalked sponge showing craticularid diplorhysis and a fine textured dictyonine skeletal net. These are the first sponges, and the first dictyid sponges in particular, reported from Cretaceous rocks of the Carnarvon Basin in Western Australia. The sponges are preserved as three-dimensional, silicified and iron-strained individuals with somewhat obscure skeletons.--Journal abstract.
