Polacanthus

Polacanthus was an armoured, spiked, plant-eating dinosaur from the Lower Cretaceous, about 132 to 100 million years ago. Polacanthus means "many spines."

Some paleontologists think that Polacanthus is the same genus as Hylaeosaurus. Fossils of this ankylosaurid have been found in England.

 Description 
Polacanthus was about 12 feet (4 m) long and about 4.8 feet (1.5 m) tall. It was a bulky quadruped that relied on its many rows of bony spikes for protection. No head is known for this genus.
