From: The multi-peak adaptive landscape of crocodylomorph body size evolution
a SURFACE model fit (using pBIC searches in the backward-phase) on tree number 18 among crocodylomorph topologies with Thalattosuchia placed within Neosuchia, using the ODCL dataset and time-calibrated with the FBD method. Attraction to unrealized low or high trait optima are highlighted in blue and red, respectively. b Simplified version of a, with independent multi-taxon regimes collapsed to single branches
