Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. Penkalski 2018 | A large (6+ m) ankylosaurine characterised primarily by the presence of large (>25 cm), rugose, sharply keeled, plate-like osteoderms, some with pointed, beak-like ends; snout constricted rostral to orbits; premaxillary scoop rounded and relatively narrow; vomer overlaps fused premaxillae caudally; occipital condyle large; squamosal horns low, rugose and broad-based, with (pitted) caudal apex; tooth crowns highly sculptured; weak ventral flexion of preacetabular process of ilium; ulna long, gracile; robust pes with arcuate pedal unguals; h.r.1 medial osteoderms elongate and partially keeled with conical prominence; h.r.1 laterals with caudal apex and curved but unkinked (i.e., non-sigmoidal) keel. P. coombsi is distinguished from Euoplocephalus and Anodontosaurus by skull shape and armour texture. P. coombsi is distinguished from D. acutosquameus in having only two sacral ribs aligned with the acetabulum, by one less sacrocaudal (4-3-1 count), by less curvature of the preacetabular process, by a more robust sc1, and by arcuate pedal unguals. P. coombsi differs from Scolosaurus, O. horneri, and Z. crurivastator in skull and squamosal horn shape. |
