The inclusion of "Scleromochlus" altered the topology obtained to varying extents, although both analyses recovered it as an avemetatarsalian. In the Nesbitt dataset, "Scleromochlus" collapsed Avemetatarsalia into a polytomy containing itself, "Spondylosoma", the other aphanosaurians, pterosaurs, lagerpetids, and dinosauriforms. Meanwhile, in the Ezcurra dataset, "Scleromochlus" formed a polytomy with lagerpetids and dinosauriforms. Nesbitt "et al." emphasized that characteristics of pelvic and leg anatomy could not be assessed for "Scleromochlus" due to conflicting descriptions and poor quality of skeletal casts; these characteristics play a substantial role in the topology of basal avemetatarsalians.
