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.
[1] The Murgon fossil site is located near Kingaroy in south-east Queensland (26° 14' S, 151° 57' E).
Material that represents the fossil component is the MP1 horizon in a sequence of lacustrine clays from Boat Mountain.
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[2]
