       Once considered a possible nodosaurid,‭ ‬Aletopelta was confirmed as an ankylosaurid when it was formally described in‭ ‬2001.‭ ‬This interpretation came about mainly from study of the osteoderm armour which is more like the armour of known ankylosaurs and less like that of nodosaurs.‭ ‬By extension Aletopelta would be assumed to have had a broader skull as well as a bony club on the end of the tail like in relative genera,‭ ‬though in Aletopelta these have so far not known to have been preserved.
       The name Aletopelta means‭ ‘‬wandering shield‭’ ‬a reference to the fact that the Aletopelta holotype remains have actually travelled a long way since they first came to rest.‭ ‬The holotype remains of Aletopelta were located on the Peninsular Ranges Terrane,‭ ‬and accounting for seventy million years‭’ ‬worth of continental drift Aletopelta would have actually lived much closer to what is now Mexico during the Cretaceous.‭ ‬In addition to this the holotype remains have been interpreted as being washed out‭ ‬to‭ ‬sea shortly after the animal died,‭ ‬perhaps with flood waters or a storm surge.‭ ‬When they finally settled on the bottom,‭ ‬they seem to‭ ‬have formed the basis for a miniature reef.
