Cited by genera

Patagopelta
Recovered Patagopelta as a non-eurypodan thyreophoran or an early ankylosaur, depending on the tree.
Spicomellus
Considers it most likely an early-diverging ankylosaurid, inside Ankylosauridae in the implied-weights tree and in a polytomy with Ankylosauridae and Nodosauridae in the reduced consensus tree.

Cited by clades

Parankylosauria
New Spicomellus phylogeny dispersed putative Parankylosauria members across Ankylosauria and Thyreophora
