Dasyuromorphia (/dæsijʊəroʊˈmɔːrfiə/, meaning "hairy tail"[2] in Greek) is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the extinct thylacine.

Just as Northern Hemisphere carnivores like cats, mongooses, foxes and weasels are much more alike in structure than, for example, camels, goats, pigs and giraffes, so too are the marsupial predators constrained to retain general-purpose, look-alike forms—forms which mirror those of placental carnivores.

The primary specialisation among marsupial predators is that of size: prior to the massive environmental changes that came about with the arrival of humans about 50,000 years ago, there were several very large carnivores, none of them members of the Dasyuromorphia and all of them now extinct.

Those that survived into historical times ranged from the wolf-sized thylacine to the tiny long-tailed planigale which at 4 to 6 grams is less than half the size of a mouse.
