1998. A ceratopsian dinosaur from China and the early evolution of Ceratopsia. In: Carpenter, K. & Currie, P.J. Quantitative aspects of relative growth and sexual dimorphism in. Explore Stewf's photos on Flickr. [15] The cladogram presented below is a combination of Xu, Makovicky, and their colleagues' most recent work. While percieved to be herbivores, there is evidence that at least some basal ceratopsians, such as Psittacosaurus were omnivores. Asiaceratops and Turanoceratops are each considered nomen dubium and not included. RootsFinder is a free family tree that makes family history easy to research and easy to share and integrates with FamilySearch Royal Belgian Institute of Natural Sciences, Institute of Vertebrate Paleontology and Paleoanthropology, https://paleontology.fandom.com/wiki/Ceratopsia?oldid=5118. Along with the predentary bone, which forms the tip of the lower jaw in all ornithischians, the rostral forms a superficially parrot-like beak. Take your favorite fandoms with you and never miss a beat. (Eds.). You H., Li D., Lamanna, M.C., & Dodson, P. 2005. Following is a list of ceratopsian genera by classification and location: There are several fragmentary Asian forms which may or may not be valid: Asiaceratops, Kulceratops, Microceratus, and Turanoceratops. [1], Ceratopsians are easily recognized by features of the skull. These facts appear to indicate that some ceratopsians were the dominant herbivores in their environments. The accuracy and completeness of the data cannot be guaranteed. This will dip into the often maddening world of taxonomy, the classification of living things, which is an even more difficult undertaking when dealing with a source of data as fragmentary as the fossil record. Such a structure would not be needed if ceratopsians had weak, flimsy bites. 2003. 1998. Redescription of neoceratopsian dinosaur. In: Carpenter, K. & Currie, P.J. The Ceratopsoidea includes animals like Zuniceratops which are more closely related to the family Ceratopsidae. This triangular appearance is accentuated, in later ceratopsians, by the rearwards extension of the parietal and squamosal bones of the skull roof, to form the neck frill. Another group, Leptoceratopsidae, includes mostly North American animals that are more closely related to Leptoceratops. As the ICZN does not govern taxa above the level of superfamily, this is unlikely to change. Ceratopsian Dinosaurs List of some ceratopsian dinosaurs. On a new genus of basal neoceratopsian dinosaur from the Early Cretaceous of Gansu Province, China. In: Weishampel, D.B., Dodson, P., & Osmolska, H. Entries may include names, family relationships, and dates and places of events. A derived ceratopsid: Triceratops model at the Royal Belgian Institute of Natural Sciences. Triceratops was the largest of this group of family and its brow horns were nearly up to a meter long. None have used every taxon listed above and many of the differences between the studies are still unresolved. [9] Coronosaurs show the first development of the neck frill and the fusion of the first several neck vertebrae to support the increasingly heavy head. You H. & Dodson, P. 2004. A beaked non-avian dinosaur is not unusual, but ceratopsian beaks are incredibly deep and robust compared to the flattened, spatulate bill of hadrosaurs or the slender croppers of other beaked dinosaurs. [16] The two presented this analysis again in 2004. (Ed.). There have been several cladistic studies performed on basal ceratopsians since 2000. A basal ceratopsian with transitional features from the Late Jurassic of northwestern China. Marsh considered the group distinct enough to warrant its own suborder within Ornithischia.[4].
