Ankylosaurs used their tail clubs to battle each other
This paper from Biology Letters has found new evidence for how armoured dinosaurs used their iconic tail clubs. The remarkable fossil has spikes that appear to have been broken and re-healed whilst the dinosaur was still alive. These injuries are thought to have been caused by a strike from another ankylosaur’s massive tail club, suggesting that these dinosaurs had complex behaviour, possibly battling for social and territorial dominance.
