psittacosaurus

Psittacosaurus: a very early ceratopsian dinosaur. This genus is among the most documented of dinosaurs. This is because there are so many fossils of it that have been found. Some fossils have even given us many details about its skin and flesh. It has randomly scattered large scales, with smaller scales filling in the spaces. It also had a patch of tubular structures (maybe feathers?) on the upper tail.
