  1. Results of GLS (with an autoregressive model) and OLS (untransformed data) regressions. Mean and maximum body size only for members of the crown-group Crocodylia, represented by mean and maximum values of log-transformed cranial measurements (DCL and ODCL), in millimetres. N = 10 in all four datasets (number of time bins analysed). Palaeotemperature data from [137], represented by δ18O data from the Late Cretaceous to Recent. Only significant correlations (p <  0.05) are shown
