Aletopelta coombsi

Reptilia - Ankylosauridae

Taxonomy
Aletopelta coombsi was named by Ford and Kirkland (2001). Its type specimen is SDNHM 33909, a partial skeleton (eight teeth, fragmentary scap- ulae, partial humerus, partial ulna, possible fragment of right ?radius, ulna, partial left and possibly right ischium, femora, t), and it is a 3D body fossil. Its type locality is Carlsbad Ankylosaur (SDNHM Loc. 3392), which is in a Campanian offshore mudstone/sandstone in the Point Loma Formation of California.

It was considered a nomen dubium 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: hexagonal pelvic osteoderms forming semi-continuous sheet over the pelvis; unlike Glyptodontopelta, pelvic osteoderms do not have dendritic surface texture; unlike Stegopelta, first cervical half ring is composed of osteoderms fused to underlying bony band, not closely appressed adjacent osteoderms.
