The Phascolarctidae (φάσκωλος (phaskolos) - pouch or bag, ἄρκτος (arktos) - bear, from the Greek phascolos + arctos meaning pouched bear) is a
family of
marsupials of the order
Diprotodontia, consisting of only one extant species, the
koala,[1] and six well-known fossil species, with another six less well known fossil species, and two fossil species of the genus Koobor, whose taxonomy is debatable but are placed in this group. The closest relatives of the Phascolarctidae are the
wombats, which comprise the family
Vombatidae.[2]
