Marginocephalian dinosaurs employ metaplasia to grow their horns, cranial ornaments, domes and shields as they rapidly remodel their skulls. All of them were quadrupedal herbivores from the Late Cretaceous, most of them coming from North America. This elaboration of typical ceratopsian ornaments provides an opportunity to test hypotheses of ceratopsian facial skin morphology and function.

Approximately 20 feet long and weighing more than 2 tons, the newly identified plant-eating dinosaur represents the oldest known large-bodied horned dinosaur from Canada. Dinosaur - Dinosaur - Pachycephalosauria: In important respects the pachycephalosaurs conformed to the basic ornithopod body plan, and there is some evidence that pachycephalosaurs actually evolved from (and are therefore members of) ornithopods, perhaps similar to hypsilophodontids. Ceratopsia (Greek: "horned faces") is a group of herbivorous, beaked dinosaurs which thrived in what are now North America and Asia, during the Cretaceous Period, although ancestral forms lived earlier, in the Jurassic. The horned dinosaur Pachyhinosaurus possesses rugose bony bosses across the skull roof in lieu of the projecting bony horn cores seen in most ceratopsians. Traditionally Greek shields were wooden shields, although at Medieval Armour, we also offer a number of Greek steel shields, which allows any ancient warrior enthusiast to choose between a variety of materials and designs.

Chasmosaurinae includes Triceratops… Ceratopsids are a family of ceratopsians that includes long-horned and large-frilled herbivores, being the most notorious, naturally, the Triceratops. Horned Hairdos: Einiosaurus & Achelousaurus Well, it’s true: ceratopsids have really bizarre hairdos. Evolutionary novelties of the neoceratopsians include. Xenoceratops foremostensis (Zee-NO-Sare-ah-tops) was identified from fossils originally collected in 1958. Centrosaurine ceratopsids, the group that includes Machairoceratops, were herbivorous dinosaurs known for their iconic, parrot-like beaks, enlarged noses, … A new horned dinosaur discovered in Utah had two spikes projecting from the back of its neck shield, according to a study published May 18, 2016 in the open-access journal PLOS ONE by Eric Lund from the Ohio University Heritage College of Osteopathic Medicine, US, and colleagues. Spiclypeus is a combination of two Latin words meaning "spiked shield" in reference to the spiky frill used by the dinosaur as a defence against predators and shipporum is in honour of the Shipp family.

The name Xenoceratops means alien-horned face, referring to the strange pattern of horns on its head and the scarcity of horned dinosaur fossils from this part of the fossil record. “Starting 80 million years ago, the large-bodied horned dinosaurs in North America underwent an evolutionary explosion,” said Ryan. Ceratopsidae is made up of two lineages: the Chasmosaurinae had large eye horns and small nose horns, and the Centrosaurinae had small eye horns and large nose horns. The most unexpected thing is a pair of bony “hooks” curving downwards from the top of the shield; for some reason, they are often taken out in Centrosaurus models or drawings.
