This is interesting, because it means that this 6-genus clade (which contains
genera that are Cretaceous in age, or at least close to the Jurassic-Cretaceous
boundary) is basal to the Late Jurassic _Brachosaurus_.
Royo-Torres et al. (2006) recovered _Galvesaurus_ (as _Galveosaurus_) in the
Turiasauria clade, along with _Losillasaurus_ and _Turiasaurus_. I wonder if
the _Losillasaurus_-_Turiasaurus_ clade was retained in Barco's analysis. How
secure is Turiasauria?
