Fig. 4 | Scaling of the skeletal mass across amniotes' body mass range. Regressions based on extant terrestrial mammals (grey line) and extant cetaceans (blue line).The estimated values for extreme terrestrial amniotes, sirenians (either measured or estimated) as well as the results of our estimations for P.colossus are also shown. Each data point corresponds to a distinct species (specific mean for the largest extant cetaceans, B.musculus and Physeter macrocephalus), except for extant sirenians (represented by two species). The horizontal and vertical bars indicate the maximum and minimum estimates (some are too small to be visible).Scales are logarithmic. Human height, 1.8 m (scale for larger silhouettes); penny diameter, 2 cm.See the Supplementary Methods and Supplementary Data 2.
