At right are shown palatal (above) and dorsal (below) views of the cranium of N. dicksoni, which were photographed by the curator of the Thylacine Museum during a visit to the University of Sydney in 2002.  Other thylacinid genera that have been found at Riversleigh include Badjicinus, Maximucinus, Muribacinus, Ngamalacinus, and Wabulacinus.  Although the thylacinid family was once known only from the modern species, T. cynocephalus, the discoveries that have been made at Riversleigh, especially in recent years, have greatly expanded our understanding of the evolutionary history of this and other Australian marsupial groups.

    Along with the Naracoorte Caves of South Australia, Riversleigh was designated a World Heritage Site in 1994.  Rare fossil sites such as these are integral to our understanding of the history of life, and must therefore be carefully preserved and protected.
