Polacanthus among tall grass

The armored herbivore fills the center of the scene, surrounded by high blades of grass. It is presented in side view, making the many sharp spikes along its back especially noticeable. Broad sections of armor cover its sturdy body, while the open area above the dinosaur contains no additional scenery.

Armor for a low-browsing herbivore

Polacanthus was an armored dinosaur whose name refers to its many spines. It walked on four legs and fed on vegetation within reach of its relatively low head. Its back included plates and spikes, and the heavily protected area around its hips formed an especially strong shield.
