Evidence of arthritis in the jaw of an eight-metre pliosaurus was uncovered by researchers in Bristol.

The disease would have been a bummer for the carnivorous creature, capable of ripping other dinosaurs to shreds with its 20cm teeth.

The degenerative joint disease would have stopped the dino from feeding and led to the old dear’s starvation.

Dr Judyth Sassoon, of Bristol university, discovered the condition in the pliosaurus’s left jaw joint when studying a specimen at Bristol City Museum and Art Gallery.

Dr Sassoon said: “In the same way that aging humans develop arthritic hips, this old lady developed an arthritic jaw.”

If only someone had the gumption to invent those nifty copper bracelets 150 million years back.
