I had thought that PhyloCode required a family-level clade to include
the nominative genus as an internal specifier. I know this has not
traditionally been the case in phylogenetic nomenclature where
Ceratopsidae is concerned (e.g. Sereno, 1998, defined Ceratopsidae to
include _Pachyrhinosaurus_, _Triceratops_, their most common recent
ancestor and all descendents). If I'm wrong on this, set me straight.

Family-level clades require a reference genus.
