El crani de Sylviornismostra una articulació crania rostral completament mòbil, amb dos còndils articulars situats sobre el rostrum, el qual s'insereix al crani en dues superfícies articulars allargades. La presència de dos procesos rostropterigoideus sobre el basisfenoide del rostrum i la forma dels palatins permet confirmar que aquest gènere pertany als Galliformes, però les característiques altament derivades del crani justifiquen el seu emplaçament a una nova família, extingida, Sylviornithidae.
