Microceratus (meaning "small-horned") is a genus of small ceratopsian dinosaur that lived in the Cretaceous period in Asia. It walked on two legs, had short front arms, a characteristic ceratopsian frill and beak-like mouth, and was around 2 feet (0.6 m) long. It was one of the first ceratopsians, or horned dinosaurs, along with Psittacosaurus in Mongolia.
