Figure 26. Crown slenderness index versus number of genera known from teeth in Sauropodomorpha and derived clades.
The mean (white circle), standard deviation (tick mark) and range (horizontal line) of tooth breadth for each clade is indicated (log10 Sauropodomorpha slenderness index range extends towards zero as indicated by the arrow). Sketches of tooth crowns (from left to right, Euhelopus, Huabeisaurus, Phuwiangosaurus) and red field depict the wide range of crown shapes in Euhelopodidae compared to other derived sauropod clades.
