Protoceratops (/ ˌproʊtoʊˈsɛrətɒps /; lit. 'first horned face') [1] is a genus of small protoceratopsid dinosaurs that lived in Asia during the Late Cretaceous, around 75 to 71 million years ago. The genus Protoceratops includes two species: P. andrewsi and the larger P. hellenikorhinus.
Protoceratopsidae is a family of basal (primitive) ceratopsians from the Late Cretaceous period. Although ceratopsians have been found all over the world, protoceratopsids are only definitively known from Cretaceous strata in Asia, with most specimens found in China and Mongolia. As ceratopsians, protoceratopsids were herbivorous, with ...
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 ...
Country. China. Type section. Named for. Bayan Mandahu, Urad Rear Banner, Inner Mongolia. The Bayan Mandahu Formation (also known as Wulansuhai Formation or Wuliangsuhai Formation) is a geological unit of "redbeds" located near the village of Bayan Mandahu in Inner Mongolia, China, in the Gobi Desert. It dates from the late Cretaceous Period.
Ceratopsia or Ceratopia (/ ˌsɛrəˈtɒpsiə / or / ˌsɛrəˈtoʊpiə /; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Europe, and Asia, during the Cretaceous Period, although ancestral forms lived earlier, in the Jurassic.
List of marginocephalian type specimens. This list of specimens is a comprehensive catalogue of all the type specimens and their scientific designations for each of the genera and species that are included in the clade marginocephalia. Painting by paleoartist Charles R. Knight of Agathaumas, the first named marginocephalian, from 1897.
However, Polish paleontologist Łukasz Czepiński in 2020 pointed out that there are no referable specimens to Udanoceratops from the Bayan Mandahu collections, and it is most likely that these remains were confused with the concurring (and relatively large) Protoceratops hellenikorhinus. [3]
(2022) report two skulls of Protoceratops hellenikorhinus from the Late Cretaceous Wulansuhai Formation (Alxa Right Banner, Inner Mongolia, China), expanding the known geographic range of the species, and provide a revised diagnosis of P. hellenikorhinus. [149]
