When Nicholas Longrich discovered a new dinosaur1 species with a heart-shaped frill(装饰) on its head, he wanted to come up with a name just as flamboyant2(艳丽的,炫耀的) as the dinosaur's appearance. Over a few beers with fellow paleontologists(古生物学者) one night, he blurted3 out the first thing that came to mind: Mojoceratops. "It was just a joke, but then everyone stopped and looked at each other and said, 'Wait — that actually sounds cool,' " said Longrich, a postdoctoral associate at Yale University. "I tried to come up with serious names after that, but Mojoceratops just sort of stuck."

With the publication of Longrich's paper describing his find in the Journal of Paleontology, online today, the name is now official.

The dinosaur is one of more than a dozen species belonging to the chasmosaurine ceratopsid family, which are defined by elaborate(详尽的) frills on their skulls5. A plant eater about the size of a hippopotamus6(河马) , Mojoceratops appeared about 75 million years ago during the Late Cretaceous — 10 million years earlier than its well-known cousin, the Triceratops. The species, which is related to another dinosaur in Texas, is found only in Canada's Alberta and Saskatchewan provinces and was short-lived, having survived for only about one million years.

It was only after coming up with the unusual name that Longrich looked into its etymology7(语源) . Surprisingly, he found that it was a perfect fit for the species, which sported a flamboyant, heart-shaped frill on its head.

"I discovered that 'mojo(巫术,符咒) ' is an early 20th-century African-American term meaning a magic charm or talisman8(护身符,法宝) , often used to attract members of the opposite sex," he said. "This dinosaur probably used its frill to attract mates, so the name made sense." The full name is Mojoceratops perifania, with "perifania" meaning pride in Greek. (The other part of the name mojoceratops follows the convention of other related species, with "ceras" being Greek for horn and "ops" being Greek for face.)

While all ceratopsids have frills on the tops of their skulls, "Mojoceratops is the most ostentatious," Longrich said, adding that their frill is also the most heart-shaped of all the related species.

Longrich got his first clue that he might have found a new species at the American Museum of Natural History in New York, where he was studying the dinosaur fossil collection in 2008. There, he found a distinctive9 frill that didn't match anything previously10 known. Later, while sketching11 the skull4 of another specimen12 on display, which was thought to be a species called Chasmosaurus, he noticed the skull was identical to the one on the specimen next to it.

"I realized the skull on the supposed Chasmosaurus must have been a reconstruction," he explained. When he studied the front of the skull, Longrich noticed some differences from the typical Chasmosaurus, including longer horns than usual. Trips to other museums in Western Canada turned up more examples that didn't fit with the rest of the known species. "The fossils didn't look like anything we'd seen before. They just looked wrong," he said.

Finding yet another previously unknown large dinosaur species that comes from Dinosaur Provincial13 Park in Alberta, Canada-which boasts the world's most diverse dinosaur fauna-was somewhat surprising, Longrich said, because the fossils have been studied for such a long time already. "So far, we really have no good explanation for why there are so many dinosaurs14 in the area and just how they managed to coexist(共存,和平共处) ," he said.

All in all, Longrich turned up eight partial skulls of the new species, which now boasts a name with just as much flair15 as its unusually shaped head.

"You're supposed to use Latin and Greek names, but this just seemed more fun," Longrich said. "You can do good science and still have some fun, too. So why not?"
