Sinoceratops

Sinoceratops ˌsaɪnoʊˈsɛrətɒps is an extinct genus of ceratopsian dinosaur that lived approximately 73 million years ago during the latter part of the Cretaceous Period in what is now Shandong province in China. It was named in 2010 by Xu Xing et al. for three skulls from Zhucheng, China. The name of its type species Sinoceratops zhuchengensis means "Chinese horned face from Zhucheng", after the location of its discovery. Sinoceratops was a medium-sized, averagely-built, ground-dwelling, quadrupedal herbivore. It could grow up to an estimated in length and weigh up to . It was the first ceratopsid dinosaur discovered in China, and the only ceratopsid known from Asia. All other centrosaurines, and all chasmosaurines, are known from fossils discovered in North America, except for possibly Turanoceratops. Sinoceratops is also significant because it is one of the largest known centrosaurines, and is much larger than any other known basal members of this group. Sinoceratops was discovered in the Hongtuya Formation, which was deposited during the late Cretaceous. It lived alongside leptoceratopsids, saurolophines, and tyrannosaurines. The most common animal in the formation was Shantungosaurus, to which most of the material has been assigned. The animals living alongside Sinoceratops and Shantungosaurus were Zhuchengceratops, Zhuchengtitan, and Zhuchengtyrannus. The holotype specimen ZCDM V0010, consisting of a partial skull, including a braincase, was in the summer of 2008 recovered at the Hongtuya Formation of the Wangshi Group in Shandong, China. The specimen was collected in fluvial sediments that were deposited during the Campanian-Maastrichtian stages of the Cretaceous period, approximately 72–66 million years ago. Two other specimens have been recovered from the same formation. Specimen ZCDM V0011 is a partial skull that consists of the skull roof and most of the braincase, and ZCDM V0012 represents a partial braincase.

Achelousaurus

Achelousaurus (pronəˌkiːloʊ-ˈsɔːrəs,_ˌækɪˌloʊəˈsɔːrəs) is a genus of centrosaurine ceratopsid dinosaur that lived during the Late Cretaceous Period of what is now North America, about 74.2 million years ago. The first fossils of Achelousaurus were collected in Montana in 1987, by a team led by Jack Horner, with more finds made in 1989. In 1994, Achelousaurus horneri was described and named by Scott D. Sampson; the generic name means "Achelous lizard", in reference to the Greek deity Achelous, and the specific name refers to Horner.

Diabloceratops

Diabloceratops (daɪˌæbloʊˈsɛrətɒps ) is an extinct genus of centrosaurine ceratopsian dinosaur that lived approximately 81.4-81 million years ago during the latter part of the Cretaceous Period in what is now Utah, in the United States. Diabloceratops was a medium-sized, moderately built, ground-dwelling, quadrupedal herbivore, that could grow up to an estimated in length and in body mass. At the time of its discovery, it was the oldest-known ceratopsid, and first centrosaurine known from latitudes south of the U.

Timeline of ceratopsian research

This timeline of ceratopsian research is a chronological listing of events in the history of paleontology focused on the ceratopsians, a group of herbivorous marginocephalian dinosaurs that evolved parrot-like beaks, bony frills, and, later, spectacular horns. The first scientifically documented ceratopsian fossils were described by Edward Drinker Cope starting in the ; however, the remains were poorly preserved and their true nature was not recognized. Over the next several decades, Cope named several such genera and species.
