Formerly known as "Protoceratopsia", these are the primitive form of ceratopians.
The basal Neoceratopids were bi/quadrupedal, while the Coronosaurians probably were
quadrupedals. The Coronosaurians allso had clearly neck frills, and even horns on the snout.
Based on the world famous fossil "fighting dinosaurs" with a Protoceratops and a Velociraptor
it is known that a Protoceratops could to a lot of damage with it's beak, and "horn".
Although it was not a large horne, but more of a bump, it could easily crush the fragile chest
of a small theropod, and the powerfull beak could rip open, or snap off a thin bone, like in
a arm or foot.
Psittacosaurus (see cladogram page) is known to have long feather-like
fibers along the tail (?and the rest of the body?), and has been known to be omnivorous.
