Even Gauthier abandoned this name, renaming the clade _Panaves_
(Gauthier and de Queiroz, 2001). And Sereno notes online
that Benton (1999) had already named this clade _Avemetatarsalia_.

Jon Wagner proposed on the PhyloCode Mailing List that Gauthier et
al.'s "Pan-" naming convention for total clades (=panstem clades) be
used not for clade names but as a sort of notational prefix. Under
this convention, "_Avemetarsalia_" and something like "pan-_Aves_"
would be equivalent expressions (essentially "heterodefinitional
synonyms"), both available for use.
