For instance, according to the older view, the dental formula in the thylacine or Tasmanian wolf is i., c, i, p. 3, m.
The gradual passage of the thick root of the tail into the body is a character common to the Tasmanian wolf and the aard-vark, and may be directly inherited from reptilian ancestors (see Thylacine).
Other terrestrial marsupials are the wombat (Phascolomys), a large, clumsy, burrowing animal, not unlike a pig, which attains a weight of from 60 to 100 lb; the bandicoot (Perameles), a rat-like creature whose depredations annoy the agriculturist; the native cat (Dasyurus), noted robber of the poultry yard; the Tasmanian wolf (Thylacinus), which preys on large game; and the recently discovered Notoryctes, a small animal which burrows like a mole in the desert of the interior.
