It lived about 10 million years earlier than the more familiar bigger Ceratopsians. Zuniceratops was roughly 3 to 3.5 meters long (10-11 ft), weighing in around 100 to 150 kilograms (200 to 250 lb).It is the earliest-known Ceratopsian to have eyebrow horns and the oldest-known Ceratopsian from North America.
