Genus PALAEONUBECULARIA Reitlinger, 1950

Type Species. Palaeonubecularia rustica Reitlinger, 1950 .

Description. Attached, uncoiled tubular, serpentiform, gregarious test. Proloculus and early stage poorly known. Wall porcelaneous, often transformed in microgranular calcite or poorly silicified (and consequently, they are often misinterpreted as Fusulinata pseudolituotubids and Textulariata tolypamminids).

Remarks. The gregarious tubes of this genus are generally few around the substrate; nevertheless, some reefs of Palaeonubecularia have been described, in particular in the Artinskian of the Pre-Urals, Russia ( Khvorova, 1951).

Occurrence. Late Mississippian (Serpukhovian)- Late Permian (Wuchiapingian), cosmopolitan.
