Table S1 Extant species included in the study, insularity, average body mass of the species and bibliography of body mass

Figure S1 Figure S1 Graphics of the pairwise regression models (log-log scale) between a skeletal parameter (x-axis) and body mass (y-axis). The parameters used are the following: (A) width of the occipital condyle (WOC) using all species; (B) WOC–Hystricomorpha; (C) WOC–Myomorpha; (D) WOC–Sciuromorpha; (E) WOC–Muridae; (F) lower first molar area (M/1AA) using all species; (G) M/1AA–Hystricomorpha; (H) M/1AA–Myomorpha; (I) M/1AA–Sciuromorpha; (J) M/1AA–Muridae; (K) lower toothrow area (TRAA) using all species; (L) TRAA–Hystricomorpha; (M) TRAA–Myomorpha; (N) TRAA–Sciuromorpha; (O) TRAA–Muridae; (P) humerus length (HL); (Q) femur length (FL); (R) pelvis length (PL); (S) cubit length (CL); (T) tibia length (TL); (U) proximal humeral anteroposterior diameter (HAPDp); (V) distal humeral transversal diameter (HTDd); (W) distal humeral anteroposterior diameter (HAPDd); (X) distal femoral transversal diameter (FTDd); (Y) distal femoral anteroposterior diameter (FAPDd); (Z) proximal femoral transversal diameter (FTDp); (AA) proximal tibia transversal diameter (TTDp); (AB) distal tibia transversal diameter (TTDd); and (AC) proximal tibia anteroposterior diameter (TAPDp).
