Range DescriptionKakarratul, or Northern Marsupial Mole, has been collected from twelve localities in the Gibson, Little Sandy, and Great Sandy Deserts of Western Australia, Australia. In 2000 specimens were also collected at Wallal Downs on the coast between Broome and Karratha, and at Kunawarritji Community (Benshemesh 2004). Both this species and Notoryctes typhlops have been recorded in the vicinity of Warburton and may be sympatric there (Benshemesh 2004). All specimens north of Warburton and west of the Northern Territory border have been identified as N. caurinus. In addition, both species may be found in the Tanami Desert, however, this is unclear (Benshemesh 2004).
There are very few specimens (around 20), but six of these have been collected in the past decade or so, despite an enormous increase in the number of people visiting its range in four-wheel drive vehicles. Maxwell et al.’s (1996) description of two of the records indicates the importance of chance in obtaining specimens of this fossorial species. An animal was found on Talawanna Track west of Cotton Creek, Western Australia, in October 1995 (Western Australia Museum), having been excavated by a bulldozer about one metre below the surface. Another came from near Nifty Mine in March 1996 after it was found nearly dead on the surface after heavy rain.
