FIGURE 3 in Big-headed marine crocodyliforms and why we must be cautious when using extant species as body length proxies for long-extinct relatives

FIGURE 3. Bivariate plots of cranial (1, 3) and femoral lengths (2, 4) plotted against total lengths for complete specimens only (1, 2) and for all specimens (3, 4). In each case a line of least-squares regression is fitted along with a shaded area representing the confidence interval around the regression model.
