Palaeopathology is the study of fossilised lesions and diseases in ancient animals. Although pathologies fossilise under rare circumstances, they have been recorded extensively in dinosaurs and their study has contributed significantly in recent years to a more profound understanding

of the lifestyle and behaviour of these animals.

The lecture will present an overview of the pathological fossil record in dinosaurs like Tyrannosaurus, Iguanodon and Diplodocus. After that, biological implications will be presented: what kind of information can pathologies tell us about the individual and the population? Is there any behaviour we can infer from them? Did the animal die because of that pathology or did it survive? And in conclusion, what are the problems addressed in palaeopathological diagnoses?
