Hence,
Gauthier and de Quieroz (2001) revise a decade of use of Carinatae
{*Ichthyornis* + Neornithes} to turn it into a clade that is, effectively,
a senior synonym of Ornithodira by defining the taxon on a carinate keeled
sternum, and define that in such a manner that one can make pterosaurs fit
it without stretching the imagination.


Huh?  Don't they state that the carina in question must be homologous to that in _Vultur_?  The pterosaurian carina is decidedly not so (unless you're Larry Febo), so pterosaurs would not be included in this definition.
