Scientists from South Korea, the United States and Japan analyzed1 fossil evidence found in South Korea and published research describing a new horned dinosaur2. The newly identified genus(类,种,属) , Koreaceratops hwaseongensis, lived about 103 million years ago during the late Early Cretaceous period. The specimen3 is the first ceratopsian(角龙) dinosaur from the Korean peninsula. The partial skeleton includes a significant portion of the animal's backbone4, hip5 bone, partial hind6 limbs(后肢) and a nearly complete tail. Results from the analysis of the specimen were published in the 18 November 2010 online edition of the journal Naturwissenchaften: The Science of Nature. The Koreaceratops hwaseongensis is named for Korea and Hwaseong City, which yielded the fossil. It was discovered in 2008 in a block of rock along the Tando Basin reservoir(水库) . It is one of the first articulated(清晰的) dinosaurs7 known from Korea.

"This is a rare find," said Michael J. Ryan, Ph.D., curator and head of Vertebrate Paleontology at The Cleveland Museum of Natural History, who co-authored the research. "Fossils of dinosaurs have not typically been found in this region, whereas evidence of dinosaur eggs and footprints occur more commonly. This specimen is significant because it fills in a missing 20 million-year gap in the fossil record between the origin of these dinosaurs in Asia and their first appearance in North America."

At approximately 5 to 6 feet long and weighing about 60 to 100 pounds, the animal was relatively8 small compared to the geologically younger, giant relatives like Triceratops found in North America. Koreaceratops had a parrot-like face with a beak9(鸟嘴,鹰钩鼻子) at the front of its jaws10, indicating it was an herbivore(食草动物) . The claws on its hind feet suggest that it was bipedal(两足动物的) and moved at a fairly rapid speed. Koreaceratops had a unique fan-shaped tail formed by long neural11 spines12, which suggests it may have been a good swimmer, and spent part of its time hunting for aquatic13(水生的) food.
