Pearson’s correlation matrix for six measurements of the painted turtle shell from ‘observed-age’ turtles

	CCL	CCW	SCL	SCW	PL	PW
CCL	1.00
CCW	0.97	1.00
SCL	0.99	0.96	1.00
SCW	0.95	0.96	0.96	1.00
PL	0.98	0.96	0.99	0.96	1.00
PW	0.95	0.94	0.96	0.96	0.96	1.00

Note: All variables were log-transformed and correlations were significant at P < 0.001. These correlations are representative of those found across all datasets listed in Table 1 and used for analysis of size and shape. CCL = curved carapace length, CCW = curved carapace width, SCL = straight carapace length, SCW = straight carapace width, PL = plastron length, PW = plastron width.
