Its type specimen is FMNH UR88, a partial skeleton (?maxilla with three partial alveoli, ?indeterminate skull fragments, seven cervical vertebrae, two dorsal vertebrae, portions of the synsa- crum, proximal cauda), and it is a 3D body fossil. Its type locality is Conant Creek, Lander, which is in a Cenomanian estuary/bay shale/claystone in the Frontier Formation of Wyoming. It is the type species of Stegopelta. It was considered monophyletic by Vickaryous et al. (2004).

Diagnosis
ReferenceDiagnosis
V. M. Arbour and P. J. Currie 2016Differs from all other ankylosaurs in possessing the following combination of characters: pelvic shield composed of hexagonal co-ossified osteoderms; cervical half ring osteoderms not fused to an underlying band. Differs from Glyptodontopelta in the surface texture of the pelvic osteoderms, which lack the dendritic texture present in Glyptodontopelta.
