Tingamarra Fauna
The Tingamarra Fauna is associated with the early Eocene Murgon fossil site, and contains the earliest known non-flying eutherian, passerine, trionychidae turtles, mekosuchine crocodiles along with frogs, lungfish and teleost fish in Australia. The Murgon fossil site is located near Kingaroy in south-east Queensland.Geology
Material that represents the fossil component is the MP1 horizon in a sequence of lacustrine clays from Boat Mountain. The geological formation of the site is not known for certain, but may be associated with the Oakdale Sandstone formation. The area was a swamp or shallow lake at the time of deposition, though the habitat has not been determined. Potassium-argon dating of illites has given a date of about 54.6 million years, which is before Australia's separation from Antarctica and South America
