Researchers discover a second oldest-known horned dinosaur species
The Ceratopsia family is growing again. Researchers have described a new species of plant-eating dinosaur, Hualianceratops wucaiwanensis, that stood on its hind feet and was about the size of a spaniel. It is similar in age to the oldest-known member of the “horned dinosaurs,” Yinlong downsi, although both are hornless.
