The Naracoorte Caves are located along the Limestone Coast, Mount Gambier in South Australia. The Wonambi Fossil Centre writes:
Palaeontologists have been studying the fossils and bones found in the caves for over 30 years. From them they have been able to determine the range of species that made up Naracoorte’s ancient animal communities. Around 120 species of vertebrate animals have been recorded to date. They represent four of the major vertebrate groups: amphibians, reptiles, birds and mammals. The interpretive centre also shows you how the caves have acted as pitfall traps, dens and roosts for more than 500,000 years, leading to a vast accumulation of skeletal remains of reptiles, birds and mammals.
