Kosmoceratops (“ornamented horned face”) was discovered in Utah, USA, and had one of the most ornate skulls of any known dinosaur.
Living about about 75 million years ago, it’s known from a partial skeleton and an almost complete skull and is estimated to have measured around 5m long (16’4”).
Its frill was relatively short and wide for a chasmosaur, topped with a “fringe” of eight long folded-over spikes and a pair of sideways-curving hooks. Its brow horns curved sideways, and its nose horn was thin and flattened into a blade-like shape.
Overall it had a total of fifteen large horns and spikes – ten big frill spikes, two brow horns, a nose horn, and two cheek spikes – along with sixteen additional scallops along the sides of its frill.
