Anyone know why it was named "Ceratonykus"?

According to the ICZN, yes, Parvicursoridae has priority over
Mononychidae/Mononykidae. But under PhyloCode, whichever clade is defined
first (Parvicursoridae or Mononykidae) would get the gig. Neither has been
defined, AFAIK, although Mononykinae has a phylogenetic definition.

I guess that would be _Albertonykus_.
