A study aiming to determine whether body size and ontogenetic age were strongly correlated in hadrosaurid dinosaurs from the Dinosaur Park Formation (Alberta, Canada), and to test the hypothesis of a rapid growth rate of hadrosaurids from the Dinosaur Park Formation relative to those from the Two Medicine Formation, is published by Wosik et al ...
