Ankylosaurs' Tail Had a Wicked End
Tracking the evolution of these mace-tailed dinosaurs
A typical Ankylosaur had a long, flexible tail. But at some point in their evolution, that changed in the name of adding even more protection. A new study Dr. Victoria Arbour, a Canadian Post-doctoral researcher at the North Carolina Museum of Natural Sciences, found that the Ankylosaur tail became stiff, then evolved a large club-like structure on the end.
The club was likely used to to strike other Ankylosaurs, similar to the way animals with horns and antlers battle each other today.
