Reassigned species
Seven species have been referred to this genus over the years, six of which have since been reassigned to other genera:
- Palaeoscincus africanus, named by stegosaurid Paranthodon;[4]
- Palaeoscincus asper, "the rough one", a dubious tooth Lawrence Morris Lambe in 1902,[5] based on a single tooth, specimen NMC 1349 now referred to Euoplocephalus;[6]
- Palaeoscincus costatus, "the ribbed one", the type species named by Leidy in 1856, known from a single tooth, specimen ANSP 9263 found by Ferdinand Vandeveer Hayden near Fort Benton. It was the first ankylosaurian species to be named based on American material;[6] it is now considered an ankylosaurian of unknown affinities.
- Palaeoscincus latus, "the wide one" named by pachycephalosaurid;[6]
- "P. magoder", a nomen nudum name from a faunal list by Karl ("Charles") L. Henning,[6][8] the result of mistaking the German words mag oder for a specific name;
- Palaeoscincus rugosidens, "rough tooth" named by Chassternbergia. It was this species that was portrayed in most restorations of the genus.
- Palaeoscincus tutus, a renaming of Euoplocephalus tutus by Edwin Hennig in 1915.[10]
Today, the type species P. costatus and thereby the genus is considered to be an indeterminate ankylosaurian,[11][12] perhaps an indeterminate nodosaurid.[4][6][13]
