====''Nomina dubia''====
A ''[[nomen dubium]]'' is a scientific name that is of unknown or doubtful application. There are a few documented cases of this being applied to ''Basilosaurus'' in the past.

* ''Zeuglodon wanklyni'', was a supposed species of ''Basilosaurus'', that described in 1876 based on a skull found in the Wanklyn's Barton Cliff in the United Kingdom. This single specimen, however, quickly disappeared and has since been declared a ''[[nomen nudum]]'' or referred to as ''[[Zygorhiza]] wanklyni''.<ref>{{Paleodb|63087|Basilosauridae}}: Taxonomic history.

* ''Zeuglodon vredense'' or ''vredensis'' was named in the 19th century based on a single, isolated tooth without any kind of accompanying description, and {{Harvnb|Kellogg|1936}} therefore declared it a ''nomen nudum''.{{sfn |Kellogg|1936|p=264}}<ref>{{Paleodb|63141|Zeuglodon vredense (nomen nudum)}}.

* ''Zeuglodon puschi[i]'' was a species that was said to come from Poland, it was named by {{Harvnb|Brandt|1873}}. {{Harvnb|Kellogg|1936}} noted that the species is based on an incomplete vertebra of indeterminable position and, therefore, that the species is invalid.{{sfn|Kellogg|1936|p=263}}<ref>{{Paleodb|63140|Zeuglodon puschii (nomen dubium)}}.

* ''Zeuglodon brachyspondylus'' was described by [[Johannes Peter Müller]] based on some vertebrae from "''Zeuglodon hydrarchus''",<ref>{{Cite book| last = Müller | first = Johannes Peter | author-link = Johannes Peter Müller| title = Über die fossilen Reste der Zeuglodonten von Nordamerika mit Rücksicht auf die europäischen Reste aus dieser Familie| year = 1849 | pages = 1–38 | publisher = Reiner | location = Berlin | oclc = 422134028}}
