Frequency distribution of species body size for three major dinosaur clades: (a) Ornithischia; (b) Sauropodomorpha; and (c) Theropoda.

open access: yes, 2013
The Sauropodomorpha and Ornithischia are significantly negatively-skewed, while the Theropoda exhibit a bell-shaped distribution (see Table 2). All three clades are best fitted by unimodal distributions.

Individual, ontogenetic, and phylogenetic variation in the dentition of hadrosaurids (Iguanodontia: Ornithischia)

open access: yesJournal of Systematic Palaeontology
Phylogenetic analyses of Hadrosauroidea are generally well-resolved, but finer resolution within Hadrosauromorpha remains contentious. This lack of resolution is due in part to the inability of discrete traits to illustrate their natural variation, particularly relating to the dental tooth battery. Not only has the variation not been properly examined,
