Seven years ago Aetosauroides nested between
Ticinosuchus and Aetosaurus at the base of the Aetosauria in the large reptile tree (LRT, 1269 taxa) based on a line drawing of the skull lacking several parts (Fig. 1). We first talked about this nesting here in 2011.
Brust et al. 2018 bring more complete data on the skull of Aetosauroides (Fig. 1). As far as the nesting goes, the previous line drawing was good enough, despite the missing parts and cartoonish tracing.
Brust et al. excluded Ticinosuchus (Figs. 2, 3) from the cladogram. Instead they employed the unrelated Revueltosaurus and Postosuchus as outgroup taxa. As readers know by now, taxon exclusion has hampered many studies in the past and, apparently, this continues into the present.
The new data for Aetosauroides
was added to the LRT and the tree topology did not change. Revueltosaurus continues to nest with Fugusuchus, far from aetosaurs.
