First Reported Cases of Biomechanically Adaptive Bone Modeling in Non-Avian Dinosaurs.
Predator confrontation or predator evasion frequently produces bone fractures in potential prey in the wild.Although there are reports of healed bone injuries and pathologies in non-avian dinosaurs, no previously published instances of biomechanically adaptive bone modeling exist.Two tibiae from an ontogenetic sample of fifty specimens of the herbi
