Why are so many animal remains preserved so well at Riversleigh? The answer to that lies in the underlying rocks which are also limestone, but laid down in the bed of an ancient sea more than five hundred million years ago.
Skały leżące poniżej warstw ze skamieniałościami trzeciorzędowymi to wapień, wg samych geologów powstały przez znajdujące się tu dawniej morze. Jest to więc warstwa na pewno pochodzenia potopowego. Dalej czytamy:
As these rocks were exposed on what became land, rainwater began to dissolve them. The limestone-charged run-off flowed into pools, streams and lakes.
Water also carved out extensive cave systems, ideal roosts for bats and shelters for other animals. Sometimes holes in the cave roofs formed pit traps for unwary animals. The flesh decayed from the bodies of animals which died in or were washed into caves and pools, streams and lakes. The limestone rich waters quickly encased the bones in new layers of limestone, sealing them from view, but preserving and protecting them from damage for millions of years.
To co jest charakterystyczne dla tego miejsca to liczne jaskinie, doły, w których jest uwięzionych wiele skamieniałości. Tak naprawdę już ten artykuł podaje mechanizm, w jaki powstało wiele tych popotopowych skamieniałości współcześnie żyjących w Australii torbaczy.

Pewien kreacjonistyczny autor doszedł do tego samego wniosku co ja, że trzeciorzedowe skamieniałości z Riversleigh musiały powstać po potopie, jednocześnie znowu przytaczając te szczególne cechy trzeciorzędowych depozytów z Riversleigh i prawdopodobny sposób ich powstania:
The author is referring to a letter I wrote to The Australian Geologist,17 which mentioned the famous Riversleigh fossils in Queensland. These fossils are characteristic of present-day Australian fauna, and so they almost certainly formed post-Flood, after the land animals migrated to Australia from the Middle East. But they are contained within limestones of the Karumba Basin, and, judging from its scale and relationship, the basin is probably late-Flood. To have post-Flood vertebrates enclosed with a Flood deposit would seem to pose a problem.
However, the apparent problem is easily resolved when we examine the context of the fossil deposits.18 I explained this in my letter to The Australian Geologist, ‘The fossils in the limestone are actually contained in lenses which were once caves and pools formed well after the limestone was deposited.’ Thus, after the limestone was deposited, river channels, caves, pools and underground conduits dissected it. The animal remains were trapped in these spaces and fossilized. In other words, the lenses are post-Flood, not the limestone of the Karumba Basin, which is a Flood deposit.
