The effect would’ve been heightened by soft-tissue sheaths covering the bony spikes, which we can see today thanks to the dinosaur’s eye-popping preservation.

About 110 million years ago, this plant-eating dinosaur died and wound up at the bottom of an ancient ocean. In 2011, miners in Canada accidentally dug up its remains, stumbling onto a 3-D fossil so well-preserved it
