| contents | Fig. 20. Diagrams of morphological variability of specimens of Isorthoceras luhai (Stumbur, 1956) comb. nov. and Isorthoceras saaremense (Balashov, 1959) comb. nov. from Vormsi–Pirgu regional stages, Estonia. A. Angle of expansion. B. Relative chamber length. C. Relative siphuncle position. Explanation of symbols: circle = I. saaremense; filled circle = I. luhai; circle plus = types of I. dalecarlense Kröger et al., 2011; diamonds = type of Hedstroemoceras saaremense Balashov, 1959; squares = type of Michelinoceras dnestrovense Balashov, 1975. Note the difference in siphuncle position between I. luhai and I. saaremense. |
