Time to reveal the answer to this week's quiz question. You were asked: Which Ceratopsian had the largest skull of any known dinosaur? Chasmosaurus, Pentaceratops, Anchiceratops, Arrhinoceratops, Styracosaurus or Triceratops?
Answer: Pentaceratops. Living in what is now the southwestern United States during the Campanian stage of the Late Cretaceous, between 76 and 73 million years ago, Pentaceratops not only had the largest skull of any known dinosaur but also the largest skull of any known vertebrate. From the tip of the beak to the furthest edge of the neck shield, the skull measured 3.5 metres long.
