Life reconstruction of Ninumbeehan dookoodukah in a palaeoenvironment reconstruction depicting its life and burrowing across seasons: (left) Ninumbeehan dookoodukah is resting on the edge of a river with a low water table as the wet season ends; (center) a small community of Ninumbeehan dookoodukah are in their estivation burrows at the apex of the arid season; (right) the onset of the humid season brings rain, triggering a mass emergence of Ninumbeehan dookoodukah from their estivation burrows. Some individuals expire before the incoming rains, leaving them to be preserved as fossils. Image credit: Gabriel N. Ugueto.
