Arthritis makes dino sore

Wednesday, 3 Aug 2016

A team of international researchers have diagnosed the first case of a dinosaur with septic arthritis.

The prehistoric patient is a Hadrosaur, one of the duck-billed dinosaurs that lived around 70 million years ago.

Diagnosis was based on erosion of the joint and highly reactive periosteal bone growth and fusion.

According to the research team, the severity of the pathology suggested the animal suffered with the condition for some time before death. However, only the ulna and radius were found so the extent to which the condition spread to other parts of the body remains unknown.
