Skeletal reconstruction of Ahshislepelta minor, a small ankylosaur from the Late Cretaceous Kirtland Formation of New Mexico. While originally recovered as an ankylosaurid related to Gastonia, later analyses favored a nodosaurid position which this is based on. Based on the holotype SMP VP-1930, consisting of fragmentary shoulder, forelimb, and vertebral elements as well as several osteoderms. Unknown material filled in using Niobrarasaurus, Pawpawsaurus, Silvisaurus, Sauropelta, and Borealopelta. Total length is approximately 4.9 m through the centra. Notes: Osteoderm placement somewhat speculative, not all osteoderms and vertebral fragments are figured. References: Burns & Sullivan, 2011.

Strict reduced consensus at the genus level of the most parsimonious trees recovered following the phylogenetic analysis. The original dataset is based on the matrix and scorings of Zhang et al. 2019 (except for Irisosaurus) and includes 62 taxa for 364 characters. This reduced consensus displays 39 taxa. It is based on 2 MPTs of 1,300 steps each (CI = 0.33, RI = 0.69). Dashed lines mean that the exact age of the genus is uncertain. Clades: 1, Sauropodomorpha; 2, Plateosauridae; 3, Massopoda; 4, Massospondylidae; 5, Riojasauridae; 6, Sauropodiformes; 7, Lessemsauridae. Squares represent stem-based definitions, ellipses represent node-based definitions.
Ferrodraco lentoni gen. et sp. nov. holotype specimen AODF 876. All preserved elements were photographed and scaled to the same size, then articulated where possible. These were then used as the basis for the scaling of the skeletal reconstruction, the missing parts of which were based on the skeletal reconstruction of Tropeognathus mesembrinus by Mark Witton. Scale bar = 50 mm.
