New insights into the phylogeny and skull evolution of stegosaurian dinosaurs: An extraordinary cranium from the European Late Jurassic (Dinosauria: Stegosauria)

Chronogram showing temporal, palaeogeographical, and phylogenetic relationships of stegosaurian dinosaurs. Single MPT with a length of 194 steps. CI = 0.660 and RI = 0.799. The extremely fragmentary Mongolostegus exspectabilis Tumanova & Alifanov, 2018 was excluded a priori. Bremer Support values above (not showed values under 2) and Standard Bootstrap values below (not showed values under 50). The MPT was scaled in time a posteriori using the function ‘bin_timePaleoPhy’ of the package ‘paleotree’ (Bapst 2012) in the R library (R Core Team 2023). Silhouettes obtained from PhyloPic.
