A beaten up old Styracosaurus bull looks on while a younger male sizes him up and postures a bit, trying to initiate a fight. But the elder is too old for this shit.
In the late 1990s a partial skeleton of a ceratopsian was discovered in New Mexico, USA. These remains were initially thought to belong to Torosaurus, but after more of the specimen was recovered in the mid-2010s it became clear the bones actually represented an entirely new species of horned dinosaur – officially named in 2022asSierraceratops turneri.
Sierraceratops lived during the Late Cretaceous, around 72 million years ago, in what at the time was the southern region of the island continent of Laramidia. About 4.6m long (~15’), it had fairly short chunky brow horns, long pointed cheek horns, and a relatively large frill.
CORONOSAURUS “Crown lizard” Late Cretaceous, 77 million years ago
This ceratopsid was originally thought to be a species of Centrosaurus. But despite the requisite centrosaurine nose horn, plus additional barbs on its frill (“epiparietals”), Coronosaurus would still have had no trouble wearing a g*****n mask.
