Pontagrossia reticulata n. gen. et sp. is described from the Lower Devonian (Emsian) Ponta Grossa Formation, Paraná Basin. The species is based on morphological characteristics shared by three contiguous casts clearly representing a single species, if not the same individual. The shape and organization of the fossil resembles that in some sponges, but until diagnostic evidence of its affinities can be recognized in these specimens, the new taxon will be left in open nomenclature. Nevertheless, this fossil is unlike any other invertebrate, plant, or algal fossil already known from the Ponta Grossa Formation, and thus represents a novel addition to the diversified cold-water Devonian paleobiota of Brazil.
Keywords: taphonomy, taxonomy, Gondwana, marine, Malvinokaffric Realm.
