Pachycynodon is redrawn from ref. 28. The phylogeny is based on a total evidence analysis39. The position of Pachycynodon is based on a phylogeny of basal arctoids52. The ancestral state reconstruction diagram was performed using refs. 73,74, and manually edited to accommodate for the missing data (the unedited diagram is available as Supplementary Fig. 5). The coronal gyrus is marked on the endocasts in orange. Endocasts are not to scale. Image courtesy: Pusa, Enaliarctos, Potamotherium, Mionictis and all endocasts by G.A.
