Fabifenestella Morozova 1974

Description

Genus FABIFENESTELLA Morozova, 1974

Type species. Fenestella praevirgosa Schulga-Nesterenko, 1951, subsequently designated by Morozova (1974). Pennsylvanian (Upper Carboniferous, Gzhelian); Russia.

Diagnosis. Reticulate colonies of different shape, with moderately wide and thick branches and moderately wide dissepiments. Autozooecia arranged in two rows on the branches, rectangular to pentagonal in deep tangential section and fabiform in shallow to mid-tangential section. Axial wall between autozooecial rows weakly undulating. Both superior and inferior hemisepta present. Low and wide keel with alternating nodes developed (modified after Morozova, 2001, p. 53).

Remarks. Fabifenestella Morozova, 1974, differs from Exfenestella Morozova, 1974, in the presence of a low and wide keel with alternating nodes. Fabifenestella differs from Minilya Crockford, 1944, in having rectangular to fabiform autozooecial shape in mid-tangential section instead of triangular one.

Occurrence. Mississippian (Lower Carboniferous) – Upper Permian; worldwide.
