Description
Genus RHOMBOCLADIA Rogers, 1900
Type species. Rhombocladia delicata Rogers, 1900, by original designation. Pennsylvanian (Upper Coal Measures); Kansas, USA.
Diagnosis. Ramose colonies. Flattened branches bearing 4–12 zooecial rows. Vestibule weakly developed. Diaphragms rare. Superior hemisepta usually developed. Oval apertures arranged in a diagonal pattern. Autozooecial chambers rhombic in mid-tangential section. Macroacanthostyles often occurring at distal ends of autozooecial apertures. Microacanthostyles present in zooecial walls, sometimes forming star-like accumulations. Leptozooecia rarely present on the frontal surface or on lateral parts of branches. Dorsal wall very thin.
Remarks. The genus Rhombocladia differs from Chainodictyon Foerste, 1887, by having a ramose instead of a reticulate colony form and by the development of hemisepta. From Kallodictyon Morozova, 1981, it differs in colony-form, the thin dorsal wall and the absence of leptozooecia on the dorsal surface of the colony.
Occurrence. Middle Devonian – Upper Permian; worldwide.
