Treatment

Family Rhomboporidae Simpson, 1895 View in CoL Genus Rhombopora Meek, 1872

Type species: Rhombopora lepidodendroides Meek, 1872 , by original designation; Upper Carboniferous , USA .

Diagnosis.—Ramose colonies. Tubular autozooecia meet colony surface at low angles. Diaphragms can occur. Autozooecial apertures oval. One or two acanthostyles on the distal end of each aperture. Exozonal walls with abundant paurostyles arranged in a regular pattern around the apertures (translated after Gorjunova 1985).

Discussion.— Rhombopora Meek, 1872 differs from Klaucena Trizna, 1958 by the form of the autozooecia and by the absence of large acanthostyles, rare metazooecia. The rare metazooecia also distinguish it from Megacanthopora Moore, 1929 .

Stratigraphic and geographic range.—Devonian to Permian; worldwide.
