  1. Results of GLS (with an autoregressive model) and OLS (untransformed data) regressions. Mean body size represented by mean values of log-transformed cranial measurements (DCL and ODCL), in millimetres. Data from both ODCL and DCL datasets was divided into subsets with all crocodylomorphs or only non-marine species. N = 10 in all four subsets (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
