TL is total length, e is eccentricity, min and max are the minimum and maximum positions of the dimensionless ỹ,r is radius of gyration and e/r is the dimensionless lordosis ratio. The mean lordosis ratio is calculated for both the normal and the lordotic specimens. Specimens shown in Fig. 5 are in italics.
