Triptych showing Ninumbeehan in its palaeoenvironment across seasons. First:Ninumbeehan resting on the edge of a river with a low water table as the rainy season ends. Second: A small community of Ninumbeehan in their estivation burrows during the peak of the arid season. Third: The beginning of the rainy season triggering a mass emergence from their estivation burrows (some individuals would not have made it through the estivation period and would have died in their burrows)
