Region: North America (Alberta Canada and Montana and Wyoming USA)
Age: Late Cretaceous (68 to 66 million BC; Late Maastrichtian)

Episode: Death of a Dynasty
Info: One of the last, largest, and best-known of the armored dinosaurs, Ankylosaurus was the length of an elephant, the weight of a rhinocerous, and lived in North America alongside some of the last non-avian dinosaurs such as Tyrannosaurus, Triceratops, Edmontosaurus annectens, Torosaurus, and Pachycephalosaurus before the K-Pg (Cretaceous-Paleogene) Mass Extinction event that killed off and ended the reign of the (non-avian) dinosaurs, 66 million years ago. A living tank, meaning "Fused Lizard," Ankylosaurus was a well-armored herbivore with a bony, plated body and head that would've provided protection, while its bony club on the end of its tail would deliver a crippling blow to the region's ultimate alpha predator, Tyrannosaurus rex. OUCH! 

Note: Based on with permission. I also added some Avisaurus for symbiosis.

So here it is folks, everyone's favorite clubtail or ankylosaurid despite that this dinosaur is known from scant remains. I remember some of my friends in high school claim this as their favorite dinosaur and even one of my old staff workers says it was his favorite. 

Sadly, this famous armored dinosaur along with the nodosaurid Denversaurus is facing something that even its tough armor cannot protect.
