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 the Greek words "artios" (meaning complete or perfect of its kind or, with respect to numbers, even), and "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]

gollark: Hmm, yes, apparently Linux has a monotonic clock thing available.
gollark: Possibly an OS thing.
gollark: Go has its own *assembly language* because of course.
gollark: When someone asked for monotonic time to be exposed properly, GUESS WHAT, they decided to "fix" the whole thing in the most Go way possible by "transparently" adding monotonic time to the existing time handling, in some bizarre convoluted way which was a breaking change for lots of code and which limited the range time structs could represent rather a lot.
gollark: Rust, which is COOL™, has monotonic time and system time and such as separate types. Go did *not* have monotonic time for ages, but *did* have an internal function for it which wasn't exposed because of course.
