In a recent contribution Garberoglio et al. made a critical review of Agnolin et al. (2024) work, which described the southernmost lepidosaur assemblage coming from the late Cretaceous of Patagonia. In spite that Garberoglio et al. analysis has some points in favour, most of their comments were made without the original materials at hand. In any case, they arrive to very similar taxonomic conclusions to those expressed by Agnolín et al. Because of that, we still support that there existed some kind of biotic provincialism in Patagonia, far from the 'homogeneity of terrestrial Campanian-Maastrichtian faunas' proposed by Garberoglio et al.
