If these two are synonyms then you have it the wrong way round (though
seeing as both should best be treated as nomina dubia this cannot of course
I put _Craterosaurus_ first because it's been regarded as a stegosaurid for
quite a while now (once the "braincase" was identified as a vertebra).
_Regnosaurus_ was regarded as a sauropod (possibly the same as
_Chondrosteosaurus_, e.g., McIntosh ) before Barrett and Upchurch
(1995) recognized it as a stegosaurian (a huaynagosaurid, if memory serves).
As Darren notes, stegosaurs were globally distributed in the Early
Cretaceous. Outside of Asia, EK stegosaurs are known only from fragmentary
material. I don't know of any Late Cretaceous stegosaur material - unless
the Lameta taxon _Brachypodosaurus gravis_ (usually regarded as an
ankylosaur) is a stegosaur, as once thought.
