In the 1890's, a population of wombats was observed bear to the town of Deniliquin, in the Riverina district of New South Wales, Australia. They seemed to represent a species unknown to science, but before they could be investigated they disappeared, never to be seen alive again. In 1985, however, George G Scott, a researcher with a special interest in wombat taxonomy, working at Canberra's Australia National Museum, learnt that just 2 years earlier a picnicker had reputedly seen a wombat in the Riverina area, a locality not frequented by common wombats. Investigating this claim, local naturalists discovered some wombat burrows there, which appeared to be freshly made, but they did not spot any wombats. Other burrows have since been found, some containing hairs that have been shown to match very closely those from a recently uncovered taxiderm specimen prepared from a wombat now known to have been collected at Deniliquin prior to the 1890's. searches are continuing in the hope that these marsupial denizens of Deniliquin do survive....

Some believe Deniliquin Wombat belongs to Lasiorhinus krefftii (northern hairy-nosed wombat) so representing a subspecies Other Comments One very interesting fact about Lasiorhinus krefftii (northern hairy-nosed wombat) is their loss of heterozygosity. Measurements of DNA variability made on DNA extracted from specimens from extinct populations of this wombat (Deniliquin, New South Wales) revealed that Lasiorhinus krefftii (northern hairy-nosed wombat) Epping Forest populations have only 41% of the variability of the extinct population, suggesting a bottlenecked species in steady decline. animaldiversity.ummz.umich.edu/site/accounts/information/Lasiorhinus_krefftii.html

Would this be a valid subspecies or just a possible extinct population? What do you think?

I've spoken to Dr Karl Shuker myself the hair samples don't match living examples but do match some very old museum specimens - further research is still required...
