Vagaceratops was named in 2010 and showed that horned dinosaurs were more diverse than previously supposed. This four-legged plant eater lived in North America during the late Cretaceous, 75 million years ago.
The remains of several Vagaceratops skulls were excavated from the Upper DinosaurPark Formation in Alberta, Canada, during 1958. It took many yearsfor this dinosaur to be recognized as a distinct species, but in2001 it was finally regarded as a new species of Chasmosaurus called 'C. irvinensis'. This name refers to Irvine, Alberta, wherethe first specimen was found. A later study published in 2010recognized it as a distinct from Chasmosaurus and so it was given anew genus name as well, Vagaceratops, meaning 'wandering horned-face'.
Vagaceratops is unusual because it lacks brow horns and hasa square bony frill. Its frill contains a pair of large openings soit was not solid bone and wasn't a reliable shield. It was morelikely used for show than for protection, and might have beencolorful.
The horned dinosaurs or ceratopsians are sometimes referred toas the 'buffalo of the Cretaceous' because they lived in largeherds. Herds of Vagaceratops lived in Alberta during the late Campanianstage of the Cretaceous period around 75 million years ago.
