Archaeodelphis
Taxonomy
Archaeodelphis was named by Allen (1921) [Sepkoski's age data: T Ol-u Sepkoski's reference number: 746]. It is not extant. Its type is Archaeodelphis patrius. It was considered monophyletic by Uhen et al. (2008).
It was assigned to Balaeninae by Hay (1930); to Archaeoceti by Simpson (1945); to Agorophiidae by Miller (1923) and Rothausen (1968); to Patriocetidae by Slijper (1936) and Thurmond and Jones (1981); to Autoceta by McKenna and Bell (1997); to Cetacea by Whitmore and Sanders (1977), Carroll (1988) and Sepkoski (2002); to Odontoceti by Kellogg (1928), Fordyce (1981), Fordyce (2002), Geisler and Sanders (2003), Uhen (2005), Uhen et al. (2008) and Sanders and Geisler (2015); to Xenorophidae by Uhen (2008), Geisler et al. (2014), Godfrey et al. (2016) and Marx et al. (2016); and to Odontoceti by Fordyce and de Muizon (2001), Geisler et al. (2011) and Berta (2017).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. D. Uhen et al. 2008 | Teeth unknown, but apparently long-rooted, probably resembling those of Agorophius and Prosqualodon; nasals long, narrow, and flattened dorsally; maxillae covering the anterior three fourths of the orbital portion of the frontals; orbit large, with thickened rim and prominent postorbital process; parietals meeting across the vertex of the skull behind the orbits; zygomatic process of squamosal relatively small, with small and nearly horizontal glenoid fossa; mastoid region thickened and produced obliquely downward and backward to or beyond the posterior edge of the condyles which are small and protuberant. Palatals large, expanded anteriorly, separated medially for more than half their length at the back end by a deep notch at the front end of their combined margin; pterygoids widely sundered, their free margins partly overarching the narial passage. A well-marked nasal chamber is present above the anterior end of the passage, and the vomer forms a cylinder that completely encloses the basal end of the mesethmoid cartilage (Allen, 1921a) |
