	DINOSAURS: Family Ceratopsidae
		Monoclonius meaning 'single horn face' is considered to be one of the early Ceratopsidae.
		This dinosaur is rather believed to move in lush green vegetation, instead of quarrelling.
		Having such big frills it is clearly seen that Ceratopsidae were of all varieties.

	Ceratopsidae - EvoWiki (Site not responding. Last check: )
		Ceratopsidae is perhaps the most famous of all dinosaur families, and it includes the legendary Triceratops horridus, a dinosaur as beloved as it is iconic.
		Restricted in temporal range to the latest Upper Cretaceous of North America, they were also among the last of the dinosaurs, and had the dubious honor of witnessing the grim days of the KT Boundary in which the non-avialian dinosaurs, suffered extinction.
		Holophyly of Ceratopsidae is universally accepted, and synapomorphies uniting the ceratopsid lineage include:

		The newly identified plant-eating dinosaur lived nearly 78 million years ago during the Late Cretaceous Period in what is now southernmost Alberta, Canada.
		Its identification marks the discovery of a new genus and species and sheds exciting new light on the evolutionary history of the Ceratopsidae dinosaur family.
		Albertaceratops nesmoi belongs to the Centrosaurinae, one of two subfamilies of the horned dinosaur family Ceratopsidae.

		Ceratopsinae, based on the family name Ceratopsidae Marsh 1888, has priority over Chasmosaurinae Lambe 1915 both in terms of its eponymous genus (Ceratops montanus Marsh 1888) and as a taxon with a phylogenetic definition (Sereno 1998).
		The recent reintroduction of the subfamily Ceratopsinae in place of Chasmosurinae (Sereno 1998) was not adoped by recent summaries, such as Dodson et al.
		It is not reasonable to defend the use of Ceratopsidae and Ceratopsoidea and then decline use of Ceratopsinae, when they are based on the same nominotypical genus.

	Museumkennis - Ceratopsidae
		De Ceratopsidae, wat zoveel betekent als 'hoorn-gezicht', waren stevig gebouwde dinosauriërs met een zeer opvallende, zeer grote kop, voorzien van allerlei kammen, hoorns en andere uitsteeksels.
		Samen met de Protoceratopsidae vormen de Ceratopsidae de groep van de gehoornde dinosauriërs.
		Bij de Protoceratopsidae kwamen de hoorns nog niet zo uitbundig tot ontwikkeling, bij de Ceratopsidae treffen we dankzij de enorme kammen op de kop de grootste schedels uit het dierenrijk, die bij dinosauriërs als Torosaurus en Pentaceratops lengten van meer dan 2,5 meter kon halen.

	Lec. 9 - The horned dinosaurs
		The protoceratops are all of Late Cretaceous age and represent a stage of evolution intermediate between Psittacosaurus and Ceratopsidae (Lucas, 1997).
		The first specimens of Protoceratops (also Psittacosaurus) were found in the Gobi desert as a result of the Central Asiatic Expeditions led by Roy Chapman Andrews (American Museum of Natural History: Roy Chapman Andrews at http://www.amnh.org/Exhibition/Fossil_Halls/Personalities/andrews.html) of the American Museum of Natural History in the early 1920s.
		Members of the Ceratopsidae are relatively large (4 to 8 meters long) and are obligate quadrapeds.

	Ceratopsians (Site not responding. Last check: )
		Protoceratopsidas have flaring jugals and at least rudimentary parieto-squamosal frills; most lack true horn cores, but all share a number of derived characters with ceratopsids first among which is the rostral bone in front of the premaxilla, a character found in no other dinosaur.
		In 1975, the existence of a rostral in psittacosaurus was definitively demonstrated by Teresa Maryanska and Halszka Omoslska, requiring the admission of Psittacosaurus into the Ceratopsia.
		In 1986, Paul Sereno created the Neoceratopsia, comprising the Protoceratopsidae and the Ceratopsidae to stand as a sister group to the Psittacosauria as monophyletic clades within the Ceratopsia.

	Dinosaurspark.com - The Dictionary of Dinosaurs (Tyrannosaurus, Triceratops .....)
		Achelousaurus represented a transitional form between ceratopsians with modified horns like Einiosaurus (with which A. horneri shares two horns on the end of the frill), and the derived, hornless Pachyrhinosaurus (Horner et al., 1992).
		While they may or may not form a direct line of descent, all three of these species are at least closely related, and are often united in the tribe Pachyrhinosaurini, inside the subfamily Centrosaurinae and the family Ceratopsidae (Sampson, 1996; Dodson et al., 2004).
		Achelousaurus is known from the U.S. state of Montana, in the Two Medicine Formation, which preserves sediments dated from the Campanian stage of the Late Cretaceous Period, between 83 and 74 million years ago.

	.:Dinosauria:.
		With the development of the Ceratopsidae family, two sub-families had formed: one with primarily short plate, Centrosaurinae, and another one with long plate in almost all the species, Chasmosaurinae.
		These plates normally were decorated with thorns or bone nodules of diverse sizes.
		The two sub-families of Ceratopsidae are, however, differentiated for the number and size of the horns in the face.

	Literature - Horned dinosaurs and evolutionary predictions
		The Ceratopsidae is the name given to a Family of four-legged herbivores from the Upper Cretaceous of Western North America.
		The extraordinary diversity of the dinosaurs in general is no less apparent in the Ceratopsidae, all of which are documented from a few states of the US and parts of Canada.
		A limited phylogenetic analysis of the Ceratopsidae places the new taxon as the basal member of the Centrosaurinae and indicates that robust, elongate postorbital horncores that form a synapomorphy of (Ceratopsidae + Zuniceratops) are also present in Centrosaurinae.

	Neoceratopsia
		Far more spectacular were members of the North American family Ceratopsidae which attained huge sizes and sported a dizzying array of facial horns, spikes and bosses.
		On the face, many of the ornamental features of the long extinct Ceratopsidae have convergently re-evolved including horns on the nose and brow.
		Unlike the smooth-edged frill of protoceratopsians, those of cenoceratopsians may be decorated with prominent parietal knobs and epoccipital spikes.
