Dinosaurs of South Korea

Ultrasaurus (meaning "ultra lizard") is a genus of sauropod dinosaur discovered by Haang Mook Kim in South Korea. However, the name was first used unofficially (as a nomen nudum) in 1979 by Jim Jensen to describe a set of giant dinosaur bones he discovered in the United States. Because Kim published the name for his specimen before Jensen could do so officially, George Olshevsky renamed the specimen as Ultrasauros. Jensen's giant sauropod was later found to be a chimera, and the type remains are now assigned to Supersaurus.

Koreaceratops () is a genus of basal ceratopsian dinosaur discovered in Albian-aged (Early Cretaceous) rocks of South Korea.

Koreanosaurus () is a genus of orodromine neornithischian dinosaur that lived during the Campanian stage of the Late Cretaceous of what is now South Korea. One species has been described, Koreanosaurus boseongensis.

Pukyongosaurus (meaning "Pukyong lizard", after the Pukyong National University) is a genus of titanosauriform dinosaur that lived in South Korea during the Early Cretaceous Period (Aptian - Albian). It may have been closely related to Euhelopus, and is known from a series of vertebrae in the neck and back. The characteristics that were originally used to distinguish this genus have been criticized as being either widespread or too poorly preserved to evaluate, rendering the genus an indeterminate nomen dubium among titanosauriforms. A 2022 study noted that Pukyongosaurus is probably a somphos

Doolysaurus is an extinct genus of thescelosaurid ornithischian dinosaur known from the Cretaceous (Albian–lower Cenomanian) Ilseongsan Formation of South Korea. The genus contains a single species, Doolysaurus huhmini, known from the partial skeleton of a small juvenile individual. It is the first named South Korean dinosaur with diagnostic cranial material, providing important insight into the early evolution of thescelosaurid ornithischians in East Asia, and the second named basal neornithischian from South Korea after Koreanosaurus.
