Styracosaurus (Wild Safari by Safari Ltd)

3.4 (9 votes)
A smaller, 20 foot relative of Triceratops, Styracosaurus lived about 10 million years earlier than its more famous ceratopsian cousin. The apt name, Styracosaurus (“spiked lizard”), refers to the elaborate spiked frill. It also bore a horn on its nose. It isn’t clear whether these large spikes were intended to ward off hungry predators or if they were exclusively for mating purposes.
