Status of Ceratops

My name is Vahe Demirjian.

Although it cannot be currently confirmed that Ceratops is a relative of Chasmosaurus, since it is based on poor material, the age of Ceratops (Campanian, Late Cretaceous) makes it very likely that Ceratops is related to Chasmosaurus. Further excavation of more ceratopid material from the Rocky Mountain dinosaur formations may unveil the full anatomy of Ceratops. In this case, Ceratops is allied with Agujaceratops, Chasmosaurus, Dysagnus, and Pentaceratops in the tribe Chasmosaurini, sister to a second tribe of Ceratopinae, which includes Agathaumas, Anchiceratops, Arrhinoceratops, Diceratops, Polyonax, Torosaurus, Triceratops, and Ugrosaurus. Only time may tell. —The preceding unsigned comment was added by 72.194.116.63 (talk • contribs) 19:21, 3 December 2006 (UTC).[reply]

By the way, Diceratops is now called Nedoceratops

It's a striking phenomenon unique to the internet where people can respond to four year old posts and correct them on errors that were not errors at the time! ;) MMartyniuk (talk) 23:24, 23 June 2010 (UTC)[reply]

Species section

Prieto-Marquez et. al. (2006) have demonstrated that Hadrosaurus paucidens is a nomen dubium and that the characters used to place that taxon in Lambeosaurus by Ostrom (1964) are also found in other lambeosaurines (e.g. Amurosaurus).

Eoceratops is a nomen dubium provisionally referrable to Mojoceratops (Longrich, 2010), and there are no synapomorphies that would allow Chasmosaurus belli, "Bison" alticornis, and Triceratops horridus to be assigned to Ceratops; the recent description of Medusaceratops (Ryan et. al. 2010) makes clear that the ceratopsid fauna of the Judith River Formation of Montana is morphologically and stratigraphically distinct from the Dinosaur Park Formation of Alberta and the Lance and Hell Creek Formations of the Rocky Mountains. Monoclonius recurvicornis lacks synapomorphies placing it within Chasmosaurus and most likely represents an indeterminate centrosaurine.

For the reasons given above, the species section for Ceratops must be altered.

Synonymy

Ceratops; Marsh, 1888; is synonymous with Ceratops; Rafinesque, 1815. I typed in Ceratops on Nomenclator Zoologicus, here are the results. Here is the animal previously referred to Ceratops. Apparently, Rafinesque's animal is a bird that was later found to be a homonym of an already described genus. Taylor Reints (talk) 04:04, 13 February 2011 (UTC)[reply]

Never mind, I just found out that Ceratops (Rafinesque, 1815) is a nomen nudum. Taylor Reints (talk) 18:30, 13 February 2011 (UTC)[reply]
