Palaeoscincus

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 Robert Broom in 1910/1912,{{cite journal | doi = 10.1080/00359191009519357 | last1 = Broom | first1 = R. | year = 1912 | title = Observations on some specimens of South African fossil reptiles preserved in the British Museum | url = https://zenodo.org/record/1430381| journal = Transactions of the Royal Society of South Africa | volume = 2 | pages = 19–25 }} a partial jaw from the Tithonian-Valanginian-age Upper Jurassic-Lower Cretaceous Kirkwood Formation of South Africa, now known as the stegosaurid Paranthodon;{{cite journal | last1 = Coombs | first1 = Jr. | year = 1978 | title = The families of the ornithischian dinosaur order Ankylosauria | url =http://palaeontology.palass-pubs.org/pdf/Vol%2021/Pages%20143-170.pdf | archive-url =https://web.archive.org/web/20110824005345/http://palaeontology.palass-pubs.org/pdf/Vol%2021/Pages%20143-170.pdf | url-status =usurped | archive-date =August 24, 2011 | journal = Palaeontology | volume = 21 | issue = 1| pages = 143–170 }}
• Palaeoscincus asper, "the rough one", a dubious tooth taxon from the late Campanian-age Upper Cretaceous Dinosaur Park Formation of Alberta, Canada, named by Lawrence Morris Lambe in 1902,{{cite journal | last1 = Lambe | first1 = L.M. | year = 1902 | title = On Vertebrata of the mid-Cretaceous of the Northwest Territory. 2. New genera and species from the Belly River Series (mid-Cretaceous) | journal = Contributions to Canadian Paleontology | volume = 3 | pages = 25–81 }} based on a single tooth, specimen NMC 1349 now referred to Euoplocephalus;Coombs Jr., W.P. (1990). Teeth and taxonomy in ankylosaurs. In: Carpenter, K., and Currie, P.J. (eds.). Dinosaur Systematics: Approaches and Perspectives. Cambridge University Press:Cambridge, 269-279. {{ISBN|0-521-36672-0}}
• 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; it is now considered an ankylosaurian of unknown affinities.
• Palaeoscincus latus, "the wide one" named by Othniel Charles Marsh in 1892, from the late Maastrichtian-age Upper Cretaceous Lance Formation of Wyoming,{{cite journal | last1 = Marsh | first1 = O.C. | year = 1892 | title = Notes on Mesozoic vertebrate fossils | url = https://zenodo.org/record/2838842| journal = American Journal of Science | volume = 44 | issue = 260| pages = 171–176 | doi = 10.2475/ajs.s3-44.260.171 | bibcode = 1892AmJS...44..171M | s2cid = 130167326 }} also based on a single tooth, specimen YPM 4810 found in Niobrara County, Wyoming, now believed to have come from a pachycephalosaurid;
• "P. magoder", a nomen nudum name from a faunal list by Karl ("Charles") L. Henning,{{cite journal | doi = 10.1007/BF01496485 | last1 = Henning | first1 = C.L. | year = 1914 | title = Ueber neuer Saurierfunde aus Kanada und deren geologische Position | journal = Naturwissenschaften | volume = 2 | issue = 31| pages = 769–776 | bibcode = 1914NW......2..769H | s2cid = 32822243 }} the result of mistaking the German words mag oder for a specific name;
• Palaeoscincus rugosidens, "rough tooth" named by Charles Whitney Gilmore in 1930, the best-known species, a skull and partial skeleton from the late Campanian-age Two Medicine Formation of Montana,{{cite journal | last1 = Gilmore | first1 = C.W. | year = 1930 | title = On dinosaurian reptiles from the Two Medicine Formation of Montana | journal = Proceedings of the United States National Museum| volume = 77 | issue = 2839| pages = 1–39 | doi=10.5479/si.00963801.77-2839.1}} now known as Edmontonia rugosidens, or a separate genus 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.Hennig, E., 1915, Stegosauria: Fossilium Catalogus I, Animalia pars 9, 16 pp

Today, the type species P. costatus and thereby the genus is considered to be an indeterminate ankylosaurian,Carpenter, K. (2001). Phylogenetic analysis of the Ankylosauria. In: Carpenter, K. (ed.).
