Mammalia - Artiodactyla - Ziphiidae

Mesoplodon was named by Gervais (1850) [Sepkoski's age data: T Mi-u R]. It is extant. Its type is Physeter bidens. It was considered monophyletic by Uhen et al. (2008) and Lambert et al. (2009).

It was synonymized subjectively with Nodus by Hershkovitz (1961).

It was assigned to Physeteridae by Cope (1890), Newton (1891) and Palmer (1904); to Khoufechia by Moore (1968); to Ziphiinae by Gill (1871), Gill (1872), Lydekker (1887), Trouessart (1898), Trouessart (1904), Turner (1912), Zittel (1925), Weber (1928), Hay (1930), Fraser and Purves (1960) and Kasuya (1973); to Hyperoodontidae by McKenna and Bell (1997); to Cetacea by Sepkoski (2002); to Ziphiina by Mead and Brownell (2005); to Ziphiidae by Abel (1905), Abel (1919), Kellogg (1928), Simpson (1945), Ellerman and Morrisson-Scott (1951), Sherman (1952), Scheffer and Rice (1963), Barnes (1977), Loughlin and Perez (1985), Pilleri (1987), Carroll (1988), Vidal (1991), Morgan (1994), Norman and Mead (2001), Bianucci and Landini (2002), Dalebout et al.

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.

M. D. Uhen et al. 2008Head and body length is 3-7 meters; pectoral fin length is 20-70 cm; dorsal fin height is about 15-20 cm; expanse of the tail flukes is about 100 cm; only two teeth become well developed in males, one on each side of the lower jaw, and these may be lost in old age; functional teeth of females are much smaller than those of males and often do not erupt above the gums; small nonfunctional teeth may be found in both jaws (Nowak and Paradiso, 1983). True (1910a, 1913), Heyning (1989a), Mead (1989) and others gave detailed guides to osteology in living species of Mesoplodon.
