Description
The fossilized remains of Tylosaurus, a gigantic marine predator from the time of the dinosaurs, were uncovered in the Late Cretaceous of South Dakota. Gross pathology was noted on the right fore-paddle. Investigation found considerable osteophyte growth on the appendicular surfaces of the right humerus, radius, and ulna, indicative of osteoarthritis, a chronic degenerative joint disease.
