Furthermore, they occupied a variety of ecological niches, with early silesaurids (such as Lewisuchus)[10] being carnivorous and later taxa (such as Kwanasaurus)[11] having adaptations for specialized herbivory.

[13] At around the same time, Sterling J. Nesbitt et al. (2010) independently named Silesauridae as a node-based clade consisting of Lewisuchus, Silesaurus, their last common ancestor and all their descendants.

[3] Phylogenetic studies originally recovered Silesauridae as a clade sister to Dinosauria, including a variety of Triassic taxa related to Silesaurus.

[13] A large phylogenetic analysis of early dinosaurs and dinosauromorphs carried out by Matthew Baron, David Norman and Paul Barrett (2017) and published in the journal Nature recovered Silesauridae as a monophyletic sister group to Dinosauria.
