Artiofabula
Artiofabula is a clade made up of the Suina and the Cetruminantia.[1] The clade was found in molecular phylogenetic analyses and contradicted traditional relationships based on morphological analyses.[1][2]

Etymology
The name Artiofabula was derived from Greek "artios" (meaning complete or perfect of its kind or, with respect to numbers, even), and Latin "fabula" (meaning fable). The latter referred to the clade breaking up traditional views on artiodactyl taxonomy based on morphological analyses, where camels grouped with ruminants, hippos with pigs, and whales were unrelated.[1]
Phylogeny
Phylogenetic analyses of artiodactyls revealed the following relationships:[2][3]
