Librovitschiceras
Librovitschiceras is a nautilid, subclass Nautiloidea, with a triangular cross section, included in the family Aipoceratidae. Its exact relationship with other aipoceratids is uncertain. Whorls are in contact, the siphuncle is slightly removed from the venter, which has a deep sinus. Librovitschiceras lived during the Late Carboniferous in what is now western Russia. Aipoceras and Asymptoceras are possibly related.
