STYRACOSAURUS
Styracosaurus (/stᵻˌrækəˈsɔːrəs/ stə-RAK-ə-SOR-əs; meaning “spiked lizard” from the Ancient Greek styrax/στύραξ “spike at the butt-end of a spear-shaft” and sauros/σαῦρος “lizard”)[1] was a genus of herbivorous ceratopsiandinosaur from the Cretaceous Period (Campanian stage), about 75.5 to 75 million years ago. It had four to six long horns extending from its neck frill, a smaller horn on each of its cheeks, and a single horn protruding from its nose, which may have been up to 60 centimetres (2 ft) long and 15 centimetres (6 in) wide. The function or functions of the horns and frills have been debated for many years.
