Pogona Microlepidota:

The Small-scaled, or Drydale River Bearded Dragon, lives in a very small
area in north-western Australia called the Kimberly. Its habitat is open woodland
where there are grasses and low-lying shrubs (possibly for hiding places?).
Similar to, but smaller than, P. barbata, the small-scaled dragon has fewer
spikes on its throat and back than most other bearded dragons. The adult size
of this rare species is about 14cm (5.5in) snout-vent length. Range:
