Genus: Aletopelta FORD & KIRKLAND, 2001
Etymology: Greek, aletes, ‘wanderer, wandering’ and Greek, pelta, ‘shield’, a word commonly used for ankylosauris in reference to their armor. Aletes was chosen because originally, the plate containing the Peninsular Ranges Terrane, where Carlsbad and San Diego, California, are today, was somewhere opposite the middle of Mexico (Ford et al, 1998; Lund and Bottjer, 1992, Lund et al, 1991); this plate has thus been wandering northward carrying the specimen with it.

Species: coombsi FORD & KIRKLAND, 2001 (Type)
