Mammalia - Artiodactyla - Squalodelphinidae
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.
|O. Lambert et al. 2014||Huaridelphis raimondii differs from all the other squalodelphinids in smaller size (as seen in BZW and CBL); thin antorbital process of the frontal, barely thicker than the antorbital process of the maxilla in lateral view. It further differs from Notocetus and Squalodelphis in more abrupt anterior tapering of rostrum in dorsal view (see quantification below); higher tooth count, more than 28 teeth per row; short and less robust postorbital process of frontal; ante- roventral slope of flat dorsal surface of vertex; dorsoventral compression of periotic at level of pars cochlearis and superior process, producing a flat dorsal surface; and posterior process of periotic more ventrally bent, with posterodorsal margin forming a right angle with dorsal surface of body of bone. It further differs from Medocinia and Squalodelphis in dorsal opening of mesorostral groove narrower than premaxilla in rostrum base; and wider dorsal exposure of maxilla at rostrum base (premaxilla nearly reaches lateral margin of rostrum in Medocinia and Squalodelphis).|
