Fig. 38. Plot of septal angle versus apertural angle in macroconchs of Hoploscaphites nodosus (Owen, 1852) and H. brevis (Meek, 1876).

This suggests that the two angles covary such that the aperture achieved a preferred orientation at maturity irrespective of the position of the last septum. Estimates are excluded. A. Hoploscaphites nodosus (Owen, 1852). (The smallest macroconch of H. nodosus [USNM 536270] is excluded). B. Hoploscaphites brevis (Meek, 1876). C. Total sample of Hoploscaphites nodosus and H. brevis.
