"The lumbering, spiky plant-eater Polacanthus."

Polacanthus (name meaning "Many Spikes") is a genus of herbivorous ankylosaurid dinosaur that originated during the Early Cretaceous period in what is now North America and Europe. Growing 4–5 meters (13.1–16.5 ft) long. Polacanthus was distantly related to the much bigger Ankylosaurus, which, however, lived much later, was much larger than Polacanthus.


Era & DiscoveryEdit

Polacanthus lived in North America and Europe during the Early Cretaceous period from 130–112 million years ago. Polacanthus was named after a find on the Isle of Wight in 1865. 

Physical AttributesEdit

Polacanthus was a small-medium sized Ankylosaur, standing about 3 feet tall, was 13.1–16.5 feet (4–5 m) long and weighing over a ton (2000 lbs). It was among the smallest members of the ankylosaur family.

Behavior & Traits Edit

A lumbering, spiky plant-eater that accompanied herds of Iguanodon, Polacanthus were often found accompanying around Iguanodon herds, presumably, for mutual protection. Polacanthus also often gorged on conifers.
