Adams consensus showing the relationships of Monstersauria and proximal anguimorph outgroups from the morphology-only analysis (figure 48B), time-calibrated according to Borsuk-Byalinicka [2], Gao & Fox [7], Conrad et al. [12], Mo et al. [13], Ikeda et al. [15] and radiometric dates for Bolg amondol [49,53]. Branches in grey indicate volatile taxa (Morohasaurus kamitakiensis, Labrodioctes montanaensis). Blue silhouettes: palaeogeographic map of late Campanian Asia, indicating Asian origin of taxon. Green silhouettes: palaeogeographic map of late Campanian North America, indicating a North American origin of taxon. Green vertical bar indicates the late Campanian Stage.
