Protoceratop

=
  like beak, cheek teeth, and a small frill on its head. Males may have had larger frills than females, indicating that the frill may have been used in courtship and mating. Protoceratops were about 6 to 8.2 feet long and weighed roughly 900 pounds, and they were 3 feet tall. These dinosaurs lived in the late Cretaceous period about 86 to 71 million years ago, and ended toward the Mesozoic period. Protoceratops were probobly herding animals. Scientists have found bone beds, large amounts of bone deposits from the same species in one area, and big groups of nests. Each nest had 12 or more eggs, and laid in a spiral formation. Protoceratops were herbivores, plant eaters. It most likely ate cycads and other prehistoric plants with its tough hook-like beak.         =====
