Body Size Distribution of the Dinosaurs

Figure 6

Frequency distribution of dinosaur species body size for two major formations: (a) the Morrison and (b) Dinosaur Park.

Both formations showed negatively-skewed distributions, with the Morrison formation approximately unimodal and the Dinosaur Park formation best fitted by a bimodal distribution (see Table 2). These patterns should be interpreted with caution, however, due to the small number of data points for each formation.
