resembles dasyurids than other thylacinids. A fox-sized hunter of
the rainforest floor, it lived contemporarily with several other species
of thylacines also known from Riversleigh.
At right are shown palatal (above) and dorsal (below) views of the cranium
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,
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 dorsal views of the cranium of Nimbacinus dicksoni.
