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.

Ceratopsian Month #19 -- Coronosaurus brinkmani

Coronosaurus (“crowned lizard”) was a very close relative of Centrosaurus -- so close, in fact, that it was originally named as a second species of Centrosaurus itself, before being recognized as a separate genus a few years later.

Living around 77 million years ago, it was a medium-sized centrosaur about 5m long (16′4″). Multiple specimens are known from two bone beds in Alberta, Canada, with different ages represented. Juvenile Coronosaurus skulls looked very similar to juvenile Centrosaurus, only developing their own distinct ornamentation as they matured.

Coronosaurus is a close relative of Centrosaurus, and it greatly resembled it in appearance. It was found in the Oldman Formation of Alberta, Canada, living in the Campanian age of the Late Cretaceous, about 77 million years ago. It was probably about 5 meters long, and it is known from multiple specimens. It was first thought to be a new species of Centrosaurus, before being separated out as a new genus due to it’s lack of monophyly with Centrosaurus. It was thus given its own genus. It resembles Centrosaurus and Styracosaurus in its morphology, except for differences in some of the horns. It lived alongside many other dinosaurs such as Saurornitholestes, Daspletosaurus, Troodon, Dromaeosaurus, Hesperonychus, Albertaceratops, Chasmosaurus, Anchiceratops, Brachylophosaurus, Gryposaurus, Parasaurolophus, Corythosaurus, Albertadromeus, and Scolosaurus.
