With _Yaverlandia_ removed from the Pachycephalosauria, this clade is now
solely represented in North America and eastern Asia (unless _Stenopelix_ is
a pachy; but _Majungatholus_ and _Taveirosaurus_ are not.)
BTW, other SVPCA papers sink _Suchomimus_ into _Baryonyx_ as _B.
tenerensis_; and restore _Tornieria_ as a valid genus, with _T. africana_
removed from the North American genus _Barosaurus_. Says Remes:
"terrestrial faunal exchange between Laurasia and Gondwana during the Late
Jurassic is considered improbable due to marine barriers." This provides
additional support for the idea that _Giraffatitan_ and _Dysalotosaurus_ of
the Tendaguru are valid genera, and are distinct from the Morrison genera
_Brachiosaurus_ and _Dryosaurus_, respectively.
