Seventy-six million years ago, a bizarre walking fortress—an ankylosaurian dinosaur—roamed the lush swampy forests of ancient Montana. This is the story of its life, death, and second life as one of the most complete fossil skeletons of its kind ever found.

Palaeontologists Victoria Arbour and David Evans take readers on a journey from the badlands of Havre, Montana, and the accidental discovery of a brand new species of dinosaur, to the bustling city of Toronto and the dinosaur's new home at the Royal Ontario Museum. Christened Zuul crurivastator after the iconic movie monster of the same name from the 1984 film Ghostbusters, this ankyloaur had a gnarly head, a body covered in bony spikes, and a deadly, sledgehammer-like tail. Zuul's skeleton even preserved intact skin across its back. Arbour and Evans share the latest scientific research on this outstanding new dinosaur: its identification as a new species, the evolution of its defensive armour and unusual weaponized tail, and how it came to be so incredibly preserved.

Zuul: Life of an Armoured Dinosaur is an intimate look at the amazing adaptations that helped Zuul survive in the twilight years of the Age of Dinosaurs.
