Document Summary

Ceratopsia: the horned dinosaurs: ceratopsia, well-studied group, have a lot of information because have a big fossil records, some species are very large, have very strong legs, especially forelimbs, to carry heavy head. Basal neoceratopsians (including protoceratopsids, leptoceratopsids: frill not yet been developed elaborately, 3. Lawrence lambe (ottawa: centrosaurus, chasmosaurus, easily recognized by its frill because of large openings, and how slender the head becomes as it goes to the rostral bone. Large amount of growth to go from hatchling to full size dinosaur: brooding (settling on nest) behaviour and parental care of dinosaurs is of great interest, some dinosaurs were absolutely huge, making brooding hard. Locomotion: comparable to rhinoceros, usually slow, but able to charge, tracks are uncommon, 2-4 km/hour, maximum running speed 30-35 km/hr, a herd of them charging can be very destructive and leave behind many dead.
