[= Alternifenestella Termier and Termier, 1971 View in CoL ]
Type species. Fenestella spinosa Condra, 1902 . Lower Permian (Wolfcampian); North America .
Diagnosis. Reticulate colonies with relatively wide and thick branches and relatively thin dissepiments. Autozooecia arranged in two rows on the branches. Autozooecia triangular in mid-tangential section, triangular to pentagonal proximal to bifurcations. Narrow keel with single row of nodes developed.
Remarks. Spinofenestella Termier and Termier, 1971 differs from the genus Rectifenestella Morozova, 1974 by the triangular shape of the autozooecia in mid-tangential section.
Alternifenestella Termier and Termier, 1971 is a synonym of Spinofenestella due to the close morphological similarities of their type species, according to Hageman and McKinney (2010), though Gorjunova and Weis (2012) retained Alternifenestella as a valid genus.
Occurrence. Lower Devonian–Upper Permian.
