A Semilogarithmic biplot of septal thickness versus conch diameter at the measured septa position for all ammonoid genera included. The dashed lines indicate the linear regression lines for each ammonoid family, which are represented by specific colours. B Linear biplot of the same data, but only displaying the linear regression lines with their equation and R2
