Scientists have discovered an armoured dinosaur species called Spicomellus afer, which lived 165 million years ago and had spikes sticking out from its neck, in Morocco. Spicomellus, roughly 13 feet long and weighing one-two tons, is the oldest-known member of group of armoured dinosaurs called ankylosaurs. "The armour of Spicomellus is jaw-droppingly weird," palaeontologist Richard Butler said.
