Polacanthus (meaning many thorns) was an early armored, plant-eating Ankylosaur from the early Cretaceous period. It lived 132 to 112 million years ago in what is now western Europe.

Incursions and encounters

A sleeping herd of Polyanthus were encountered by the Anomaly Research Centre team when they accidentally ran into them when marooned in a coastal woodland in the past. The team carefully managed to move around the sleeping herd and later they observes a herd of them associating with Iguanodons.


  • Polacanthus also made an appearance in Walking with Dinosaurs.
  • Polacanthus is the first armored dinosaur to be encountered.
