Fig. 4From: Covariance of sutural complexity with whorl shape: evidence from intraspecific analyses of the Cretaceous ammonoid Desmoceras Scatter diagrams between ratio of whorl breadth and height (B/H) and index of sutural complexity (ISC). a Shell diameter of 15 mm; b shell diameter of 20 mm; c shell diameter of 25 mm; d shell diameter of 30 mm. The approximated reduced major axes are shown in the case of statistically significant correlation coefficients (p < 0.05)Back to article page
