what is the name of the oldest fossil found at riversleigh in queensland?

Answer 1

According to the website of the Riversleigh fossil center, " The site has captured and preserved a snapshot of an entire rainforest environment dating back approximately 25-30 million years" http://www.riversleigh.qld.gov.au/frame.html

"The Fossil Deposits
The deposits at Riversleigh are found over 40-60 square km and represent three different periods in time. Most are in light coloured limestone 10-25 million years old that overlie much older, darker limestones. Another time period is represented at Rackhams Roost where the bones of carnivorous bats and the creatures they caught and ate 3.5 million years ago have been found in the remnants of an ancient cave high above the Gregory River. A third time period is preserved in old river terraces where the remains of animals that lived and died in and along the Gregory River some 50,000 years ago have been found."http://www.riversleigh.qld.gov.au/frame.html

"Since 1983 the preserved remains of thousands of ancient inhabitants of northern Australia including giant pythons, carnivorous kangaroos and marsupial lions, have been recovered from Riversleigh. Almost half of what we know about the evolution of Australian mammals in the last 30 million years comes from bones found at a single site in the Riversleigh fossil beds. Amazingly half of these bones were unearthed in one hour."http://www.riversleigh.qld.gov.au/frame.html

Older rocks, about 530 million years, are common in the area, but do not contain the fabulous fossil faunas for which the area has been designated a world heritage site.

I hope that the Mount Isa Tourist Information Centre forgives the generous use of quotes here. This website makes me want to visit Riversleigh.
