Fig. 11. Morphological variation of Beloitoceras sinuososeptatum (Roemer, 1861). Circles: specimens of the Boda Limestone. Black dot: type specimen of Beloitoceras siljanense Frye, 1987. Black diamonds: types of Beloitoceras heterocurvatum Strand, 1934. Grey dot: type specimen of Beloitoceras landerense Foerste, 1935. A distinction between B. siljanense and B. sinuososeptatum is impossible based on the available material.
