_Agujaceratops_ is a new genus name for _Chasmosaurus mariscalensis_, giving
the new combination _Ajugaceratops mariscalensis_. Apparently the genus
_Agujaceratops_ appeared in the recent NMMNH Bulletin (#35) (I found this
out from Tracy Ford - thanks Tracy). I haven't seen the description by
Lucas et al. (2006), or know of the grounds for erecting this new genus, but
past studies have found _Chasmosaurus mariscalensis_ to be a troublesome
taxon, since it can't decide whether it's closer to _Pentaceratops_ or
northern _Chasmosaurus_.
