Sarcophilus harrisii (originally Didelphis ursina Harris 1807, then Dasyrurus laniarius Owen 1839, then Boitard 1842) is the extant Tasmanian devil, traditionally considered the largest dasyurid. This is confirmed in the LRT. Following the extinction of Thylacinus in 1936, Sarcophilus became the largest carnivorous marsupial.

Dissacus zanabazari (Cope 1881; Geisler and McKenna 2007; Early Palaeocene to Early Eocene) was traditionally considered a mesonychid, but here nests with the extant Tasmanian devil, Sarcophilus.
