I think there's a consensus that they are basal archosauromorphs. The dissent
- whether they form a natural group (synonymous with _Prolacertiformes_), or
are just a polyphyletic assemblage of non-archosauriform archosauromorphs
- whether or not pterosaurs are part of the same group (i.e., whether or not
they are pterosauromorphs)
- where, exactly, they go in non-archosauriform _Archosauromorpha_
