Polacanthus foxii

This knobbly skin once belonged to Polacanthus foxii, an armour-plated dinosaur. P. foxii is only known from discoveries of fragmentary skeletons and armoured plates dating back 125 million years to the Early Cretaceous Period. It was a five-metre, short-legged herbivore that ate ground vegetation. Relatively slow-moving, it relied on a thick coat of bony armour and rows of spikes along its sides for defence. The first specimen was discovered by Reverend William Fox on the Isle of Wight in 1865.
