The 1964 discovery of Deinonychus in southern Montana was groundbreaking for many reasons, mostly because it helped prove that birds are direct descendants of dinosaurs.

Interest in dinosaurs soared to new heights in the 1990s, thanks largely to the blockbuster film Jurassic Park. So too did dinosaur discoveries. Since 1990, more than 100 new dinosaur genera have been described and named. Learn more about recent dinosaur discoveries.
Bagaceratops rozhdestvenskyi was a small protoceratopsian with a big name: "baga" is the Mongolian word for "small," "ceratops" means "horned face," and the species name is in honor of Russian paleontologist A. K. Rozhdestvensky. Learn more about Late Cretaceous dinosaurs.
Centrosaurus, which means "sharp-point reptile," was named by Lawrence Lambe in 1902 from specimens found along the Red Deer River in Alberta. A number of complete skulls and skeletons have since been discovered. Learn more about the Centrosaurus.
Corythosaurus, the "corinthian helmet reptile," was one of the most abundant duckbilled dinosaurs from the Late Cretaceous of western North America. Originally found and named by Barnum Brown of the American Museum of Natural History, Corythosaurus is also one of the best known of all dinosaurs.
Dromiceiomimus ("emu mimic") has been found both in the Late Cretaceous Horseshoe Canyon and the Judith River Formation of Alberta. It is very similar to Struthiomimus and Ornithomimus, but had much larger eyes and longer, more slender arms. Learn more about the Dromiceiomimus.
Since it was named in 1979 by John Horner and Robert Makela, Maiasaura has become one of the most famous dinosaurs. It has provided information about how it cared for its young and the early development of dinosaurs. Learn more about the Maiasaura.
Panoplosaurus is known only from two partial skeletons, one of which preserves some of the armor the way it was in life. This skeleton shows that Panoplosaurus was unusual among nodosaurids because it did not have spikes on the sides of its neck.
Protoceratops andrewsi was discovered in Mongolia in 1922 by an expedition from the American Museum of Natural History led by Roy Chapman Andrews. Its genus name means "first-horned face," and its species name was in honor of the expedition's leader.
Segnosaurus galbinensis, or "slow lizard from Galbin" (a region of the Gobi Desert), was first described by Mongolian paleontologist Altangerel Perle in 1979. It was an unusual saurischian that he classified in its own family, the Segnosauridae.
The paleontological expeditions into the Turpan Basin in 1964-1966 turned up several interesting and unusual dinosaurs, ilncuding the Shanshanosaurus huoyanshanensis. Learn more about the Shanshanosaurus and other Late Cretaceous dinosaurs.
