WOMBAT , the See also:

title of the typical representatives of the marsupial See also:family Phascolomyidae (see See also:MARSUPIALIA). They have the dental See also:formula: i.-, c. g, p. m. i;=24. All the See also:teeth are Tasmanian Wombat (Phascolomys See also:ursinus). of continuous growth, having persistent pulps. The incisors are large and See also:chisel-like, much as in rodents. The See also:body is broad and depressed, the See also:neck See also:short, the See also:head large and See also:flat, the eyes small and the tail rudimentary and bidden in the See also:fur. The limbs are equal, stout and short. The feet have broad, naked, tuberculated soles; the forefeet with five distinct toes, each furnished with a See also:long, strong and slightly curved See also:nail, the first and fifth considerably shorter than the other three. The See also:hind-feet have a very short nailless first toe; the second, third and See also:fourth toes partially See also:united by integument, of nearly equal length; the fifth distinct and rather shorter; these four are provided with long and curved nails. In the typical See also:group of the genus Phascolomys we find the following characters:--Fur rough and coarse; ears short and rounded; muzzle naked; postorbital See also:process of the frontal See also:bone obsolete; ribs fifteen pairs. Vertebrae: C. 7, D.

15, L. 4, S. 4, Ca. 10-12. The wombat of See also:

Tasmania and the islands of See also:Bass's Straits (P. ursinus), and the closely similar but larger P. platyrhinus of the See also:southern portion of the mainland of See also:Australia, belong to this group. On the other See also:hand, in the hairy-nosed wombat (P. latifrons) of Southern Australia, the fur is smooth and silky; the ears are large and more pointed; the muzzle is hairy; the frontal region of the See also:skull is broader than in the other See also:section, with well-marked postorbital processes; and there are thirteen ribs. Vertebrae: C. 7, D. 13, L. 6, S. 4, Ca. 15-16.

In See also:

general See also:form and See also:action wombats resemble small bears, having a somewhat similar shuffling manner of walking, but they are still shorter in the legs, and have a broader and flatter back. They live entirely on the ground, or in burrows or holes among rocks, and feed on grass, roots and other See also:vegetable substances. They See also:sleep during the See also:day, but wander forth at See also:night in See also:search of See also:food, and are shy and See also:gentle, though they can bite strongly when provoked. The only See also:noise the Tasmanian wombat makes is a See also:low hissing, but the hairy-nosed wombat is said to emit a short See also:quick grunt when annoyed. The prevailing See also:colour of the last-named See also:species, as well as P. ursinus of Tasmania, is brownish See also:grey. The large wombat of the mainland is variable in colour, some individuals being See also:pale yellowish See also:brown, others dark grey and some See also:black. The length of the head and body is about 3 ft. Fossil remains of wombats, some of larger See also:size than any now existing, have been found in caves and See also:Pleistocene deposits in Australia.
