A new study conducted by American researchers reveal that osteoarthritis may be a very old disease with even dinosaurs likely to have struggled with the condition.

Some modern birds are susceptible to osteoarthritis, the degeneration of bone and cartilage in joints.
Curious about when the condition first appeared, the researchers examined the fossilised anklebones of ancient birds and feathered dinosaurs held in Chinese museums.
Three of the 10 available fossils of Caudipteryx showed signs of osteoarthritis, the News Scientists reported.
Why Caudipteryx, which was the size of a peacock, should have been prone to the condition is a mystery: osteoarthritis is most common in smaller birds today, said Rothschild.
