In the intervening years, scientists have recovered fossils from more than 80 individual Auroraceratops, bringing this small-bodied plant-eater into the ranks of the most completely known dinosaurs. It is now one of the few very early horned dinosaurs known from complete skeletons. In a collection of articles appearing as Memoir 18 in the Journal of Vertebrate Paleontology this week, researchers from the University of Pennsylvania, Indiana University of Pennsylvania, the Chinese Academy of Sciences, Gansu Agricultural University, and other institutions describe the anatomy, age, preservation, and evolution of this large collection of Auroraceratops.

Their analysis places Auroraceratops, which lived roughly 115 million years ago, as an early member of the group Ceratopsia, or horned dinosaurs, the same group to which Triceratops belongs. In contrast to Triceratops, Auroraceratops is small, approximately 49 inches (1.25 meters) in length and 17 inches (44 cm) tall, weighing on average 34 pounds (15.5 kilograms). While Auroraceratops has a short frill and beak that characterize it as a horned dinosaur, it lacks the "true" horns and extensive cranial ornamentation of Triceratops.

"When I first saw this animal back in 2004, I knew instantly it was a new kind that had never been seen before and was very excited about it," says paleontologist Peter Dodson, senior author on the work and a professor with appointments in Penn's School of Veterinary Medicine and School of Arts and Sciences. "This monograph on Auroraceratops is long-awaited."

In 2005, Dodson and his former students Hai-Lu You and Matthew Lamanna named Auroraceratops (in Latin, "dawn's horned...
