The longest and largest ceratopsians Top 10

Triceratops is by far the best-known ceratopsians

Ceratopsia or Ceratopia (Greek: “horned faces”) is a group of herbivorous, beaked dinosaurs, which thrived in what are now North America, Europe, and Asia, during the Cretaceous Period, although ancestral forms lived earlier, in the Jurassic. The earliest known ceratopsian, Yinlong downsi, lived between 161.2 and 155.7 million years ago. The last ceratopsian species became extinct in the Cretaceous–Paleogene extinction event, 65.5 million years ago.

Ceratopsians ranged in size from 1 meter (3 ft) and 23 kilograms (50 lb) to over 9 meters (30 ft) and 5,400 kg (12,000 lb).

Characteristics

Ceratopsia is an order of dinosaurs that includes the well-known triceratops. These dinosaurs are characterized by their unique skulls, which feature a variety of bony horns and frills. They lived during the Cretaceous period, and were herbivores. Many ceratopsians had large bodies and were quite heavily built, with thick legs and sturdy, hoof-like feet. They are believed to have used their horns and frills for defense against predators, and possibly for display purposes as well. Ceratopsians are known to have inhabited what is now North America, and some species are also known to have lived in Asia and Europe.

Ceratopsia is a diverse group of dinosaurs that includes a wide range of species, ranging in size from relatively small to quite large. Some of the smaller ceratopsians, such as Protoceratops, were about the size of a sheep, while larger species like Triceratops could reach lengths of up to 30 feet and weigh up to 12 tons.

One of the most distinctive features of ceratopsians is their skull, which was typically long and wide, with a variety of bony protuberances, including horns and frills. The horns and frills served a variety of purposes, including defense against predators, display during mating rituals, and possibly for intraspecific aggression.

In addition to their skulls, ceratopsians also had other unique physical characteristics. They had strong, sturdy legs and hoof-like feet, which they used to support their large bodies. They were herbivores and likely used their sharp, beak-like jaws to tear off and grind up plant material.

Overall, ceratopsians were an important and diverse group of dinosaurs that played a significant role in the ecosystems of their time.

Taxonomy

Ceratopsia is a group of dinosaurs that belongs to the suborder Ornithischia. Within the suborder Ornithischia, ceratopsians are classified as part of the infraorder Ceratopsomorpha, which also includes the pachycephalosaurids. The order Ceratopsia includes several families, including Ceratopsidae, which includes the well-known Triceratops, and Protoceratopsidae, which includes the smaller Protoceratops.
