Ancient Sea Reptile With Gammy Jaw Suggests Dinosaurs Got Arthritis Too

15th May, 2012

Palaeontologists in Bristol have observed what they believe is the equivalent of arthritis in the jaw-bone of a Pliosaur unearthed in Wiltshire, thought to be the first discovery of such a disease in a marine reptile.

Marks from teeth caused by subsequent displacement of the lower jaw suggest this specimen lived and survived with the disease for some time. Aspects of the skeleton suggest an elderly individual which would be expected if the form of arthritis is similar to that seen in modern animals.
