Machairoceratops is a genus of centrosaurine ceratopsian dinosaur that lived in North America during the late Cretaceous. At the time of the genus description in 2016, Machairoceratops is only known from partial skull and horn remains. We can however ascertain a few facts about this dinosaur. One is that Machairoceratops was a centrosaurine ceratopsian, a type known to have favoured elaborate growths of horns as opposed to having a huge neck frill. Another is that Machairoceratops had two large horns growing up from the brow. Finally there were two more horns that grew from the top of the frill and then curved forwards. It is these two horns that were the inspiration for the name Machairoceratops which translates as ‘bent sword horned face’.
