Klembara et al 2024 look at Brouffia
To their credit:
The authors employed DGS colors to the crushed (essentially 2D) fossil of Late Carbonierous Brouffia orientalis (Fig 1)

To their discredit:
The authors cherry-picked taxa and thus did not employ the last common ancestor of the Reptilia = Amniota in the LRT: Silvanerpeton along with LRT recovered outgroups. Instead the authors employed the basal archosauromorph, Gephyrostegus bohemicus, thereby overlooking the basal Viséan split following Silvanerpeton dividing reptiles into Lepidosauromorpha and Archosauromorpha in the LRT. This hypothesis goes back a dozen years here.
With too few taxa Mesosauria cannot nest with ichthyosaurs and thalattosaurs because the latter two clades are omitted. Instead mesosaurs nest with dissimilar bolosaurs by default in Klembara et al
Similar problems arise elsewhere without a valid taxon list that goes deep enough and wide enough with a long list of outgroup taxa…like the LRT.
