A newly described horned dinosaur with peculiar ornamentation was a close relative of Triceratops, paleontologists have found. The dinosaur had a longer nose horn than Triceratops, and two small horns above its eyes. But its most distinctive feature was a radiating frill, a set of large, pentagonal plates like a crown atop its head. Researchers at the Royal Tyrrell Museum of Palaeontology in Canada named their find Regaliceratops peterhewsi. They first stumbled on the bones sticking out of a cliff along the Oldman River, in southeastern Alberta, about a decade ago. Like other horned dinosaurs, Regaliceratops probably evolved during the late Cretaceous, 65 million to 100 million years ago. Its nearly complete skull is described in the journal Current Biology.
