PARIS - Palaeontologists in Utah on Wednesday said they had found the fossil of a strange horned dinosaur which roamed an island continent known as Laramidia.
Dubbed Nasutoceratops titusi, the creature lived during the Late Cretaceous about 76 million years ago.
It belonged to the family of herbivore ceratops dinos, of which the famous triple-horned triceratops was a member.
N. titusi is "remarkable" even for a ceratops, according to the researchers.
Its skull - uncovered nearly intact - comprised an oversized snout, extraordinarily long, blade-like horns that pitched forward over the eyes, and a trademark bony frill at the base of the head.
From horntip to tailtip, it was about four metres (14 feet) long.
All ceratopsids have greatly enlarged nose regions, but Nasutoceratops is a champion.
Why, though, is unclear.
