How big is 漂泊信天翁?

A small, parrot-beaked ceratopsian dinosaur from the Early Cretaceous (approximately 125–100 million years ago). It measured about 6.5 feet (2 meters) in length and weighed around 44 pounds (20 kilograms). Known for its distinctive short beak, similar to a parrot's, Psittacosaurus was a herbivore, feeding on tough vegetation. Some species had long filament-like structures on their tails, which might have been used for display.

A genus of pachycephalosaurid dinosaur from the Late Cretaceous (around 66 million years ago). Its name, Dracorex hogwartsia, translates to \"dragon king of Hogwarts,\" inspired by its dragon-like appearance. Dracorex had a flat skull adorned with spiky horns and knobs. Though debated whether it represents a juvenile form of another species, such as Pachycephalosaurus, it was herbivorous or omnivorous and relatively small, around 10–12 feet (3–4 meters) long.
