Abnormal Dinosaur Bones

What caused asymmetrical bone growth in dinosaurs?

Asymmetrical bone growth could have occurred, for example, when a tendon was ripped off the bone. This probably happened during some form of exertion, such as running after prey for carnivores, or trying to escape a predator for herbivores. If bone growth continued in this area after the tendon was torn, it would often grow back in an abnormal shape.
