The distances calculated from the whole-body dataset, the cranial dataset, and the postcranial dataset were compared over the whole of the Mesozoic and also over the four time-bin intervals using Spearman-rank rho values, where P is the probability that two datasets are correlated. *P < 0.05; **P < 0.005; ***P < 0.0005.
