The taxon ranges are incorrect.

There is no documented overlap of Leptosuchus and Smilosuchus (early to mid-Norian) with any Machaeroprosopus species (mid- to late Norian). The NA Rhaetian phytosaur is Redondasaurus (possibly synonymous with Machaeroprosopus, but a different species than the Norian forms). How would this affect your discussion?
