One of the “strangest dinosaurs” ever discovered had elaborate armour including spikes of up to a metre-long projecting out of its neck, fossils have revealed.
Spicomellus, the world’s oldest ankylosaur, roamed the earth 165 million years ago and had bony spikes fused onto all of its ribs – a feature which has never been seen before in any other vertebrate species living or extinct, according to scientists.
