SURFACE model fits of trees time-calibrated with the FBD method, using the ODCL dataset. Attraction to unrealized low or high trait optima are highlighted in blue and red, respectively. a Model fit on tree number 17 with Thalattosuchia as the sister group of Crocodyliformes. Some model fits of trees sharing this same position of Thalattosuchia show simpler model configurations, with significantly fewer regimes (see text for details and Additional file 4 for all SURFACE plots). b Model fit on tree number 18 with Thalattosuchia as the sister group of Mesoeucrocodylia. c and d Simplified versions of a and b, respectively, with independent multi-taxon regimes collapsed to single branches
