Description Test free, nautiloid to compressed laterally, with a juvenarium endothyroid passing to a planispiral final coiling. Coiling follows a progressive increase of the spire with a common rapid increase of the final whorl, in species trending to the uncoiling. Secondary deposits absent. The most common septa are simple, curved backward, but also furrowed, blunt, swollen, and bifurcated. Cribrate aperture in the final whorl, rarely present in the penultimate chambers. Wall microgranular to granular with some agglutinated grains in the more ancestral forms, or with a porous tectum. (Liu et al. (2023)). Occurrence. Late Visean–early Bashkirian; Palaeotethys and Urals shelves. Rare in NW Washington, U.S.A. (Liszak & Ross 1997) but testifying probably of a Cathaysian, exotic, tectonostratigraphic terrane. (Vachard and Le Coze (2022)). [details]
