The story of the expedition and subsequent analysis of the only intact skeleton of a thylacoleo - the marsupial lion - ever found. The adventure to extract the fossil bones and the project to discover what they reveal overturns long held beliefs about marsupial mammals. The Nullarbor Plain is one of Australia's most hostile and barren landscapes. In a deep cave below the plain's surface, a secret was revealed. It was the pristine skeleton of Thylacoleo, the pouched lion. Its white bones were spread out in perfect formation as if it had only recently died. Dating the bones would only be the first shock awaiting scientists. Recreating its brain would yield even more information, which would challenge established perceptions of Australia's primordial past.
