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).
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[2]

| Patagoniophis |
P. australiensis (Scanlon, 2004) |
Many disarticulated vertebrae and fragmented ribs |

| Alamitophis[3] |

Fragmented dentary and rib along with disarticulated vertebrae. |

| Kambara |
K. implexidens and K. murgonensis |

|
| ?Madtsoia |
M.sp |
Rib head and proximal shaft |
Tuber costae is broken so not able to determine if it was robust as in madtsoiids or slender in proximal view as with the extent serpentia. Some other characteristics indicate a Patagoniophis affinity excluding the large size (3.9 by 2.6 mm), but is still smaller than Madtsoia, to which it is most similar.[4] |

QM specimens F20688 (carpometacarpus) and F24685 (tibiotarsus) from Murgon, Queensland, are fossil bone fragments clearly recognizable as passeriform; they represent two species of approximately some 10 and some 20 cm in overall length.[7] |
