A represents measurements of the upper limbs, B represents measurements of the lower limbs. Measurements with * are statistically significant. Abbreviations of the bone elements are as follows; COR = coracoid, HUM = humerus, ULN = ulna, CMT = carpometacarpus, FEM = femur, TIB = tibiotarsus, TMT = tarsometatarsus. The mean values can be found in the supplementary material ( S1 Table ).
