Some things never change - dinosaurs got arthritis too, say scientists.

Washington, May 16 (ANI): Researchers have for the first time revealed that dinosaurs suffered arthritis in their huge joints.

Imagine having arthritis in your jaw bones ... if they#39;re over 2 meters long! A new study has found signs of a degenerative condition similar to human arthritis in the jaw of a pliosaur, an ancient sea reptile that lived 150 million years ago. Such a disease has never been described before in fossilized Jurassic reptiles.

Arthritis literally means quot;inflammation of a jointquot;—and if you#39;ve ever experienced its painful symptoms, you’re not alone. An estimated 50 million American adults have arthritis, and it#39;s the number-one cause of disability in the U.S., according to the Centers for Disease Control and Prevention.

Ancient creatures resembling stout-necked Loch Ness Monsters apparently developed arthritis in their monster jaws, revealing that even such lethal killers could suffer from and eventually succumb to diseases of old age, researchers find.
