Armored dinos may have used their tail clubs to bludgeon each other

Tanklike armored dinosaurs probably pummeled each other — not just predators — with huge, bony knobs attached to the ends of their tails. Thanks to new fossil findings, researchers are getting a clearer understanding of how these rugged plant eaters may have used their wicked weaponry. Many dinosaurs known as ankylosaurids sported a heavy, potentially microwave-sized tail club. This natural sledgehammer has long been considered by both scientists and artists as a defensive weapon against predators.
