Yehuecauhceratops mudei

In April of 2016, some centrosaurine ceratopsid fossils from Mexico's Aguja Formation were described by Héctor Eduardo Rivera-Sylva, Brandon Hedrick and ceratopsian expert Peter Dodson who suspected they may have had an all new critter on their hands, but refrained from giving it a name because it was "not currently diagnosable to the generic level". But by late January of the following year, Rivera-Sylva had ditched Hedrick and Dodson to roll with a new bunch of co-authors and coined Yehuecauhceratops—Ancient horn face—for those very fossils. The previously depressing Mexican "horn faced" ceratopsid count was thus increased to a slightly less depressing four, with two-a-piece belonging to the chasmosaurine and centrosaurine branches, but, unfortunately, the heel dragging meant Yehuecauhceratops was runner up in the "first named dinosaur of 2017" race, with the title going to a large-handed Spanish iguanodontid called Magnamanus soriaensis. The funny thing is; the latter was named in a version of the Spanish Journal of Paleontology that appeared online in earliest 2017 as an empty text link with a 2016 date, but no mention of when or if the beasts within had been registered digitally with "Zoobank" (the Official Register of Zoological Nomenclature), or if permanent ink on paper copies were available to cement their validity in the eyes of the ICZN (International Commission on Zoological Nomenclature). The result could yet be overturned, if the matter is taken before the make believe scientific panel of arbritation, because six months down the line (the last time we checked) the S.J of P. website still hadn't been updated.
(Mude's ancient horn face?)Etymology
Yehuecauhceratops is derived from the Nahuatl "Yehuecauh" (ancient), and the Greek "ceras" (horned) and "ops" (face).
The species epithet, mudei, is derived from an acronym of the Museo del Desierto (MUDE).
The remains of Yehuecauhceratops were discovered in the Aguja Formation at La Salada, Ocampo, northern Coahuila, Mexico, between 2007 and 2010 during a joint expedition of Museo del Desierto and the University of Pennsylvania, led by Héctor Eduardo de Rivera-Sylva. The holotype (CPC 274) is a partial skeleton and skull.
