Life on Uluru

Some decades ago I was travelling around Australia and was lucky enough to climb Uluru. Pools on top of the rock had been produced by recent rain and, curiously, in many of them strange aquatic invertebrates were present (see photo).

This specimen is sitting in my camera lens cap, which has a diameter of 62 millimetres. It looks like an ancient trilobite. Why and how was it on top of the famous, massive rock, and what is it? What happens to the creatures when the short-lived puddles dry up?

The eggs can remain dormant for years. It is a fairly common characteristic for life in the desert. When the great salt lakes fill with rain, they come alive with fish, the eggs of which may have lain dormant for decades.

as to the why and how part of the question; the eggs of these animals are extremely small, so could easily be blown on the wind and stick to any area of liquid they come across where they would then hatch. why are they there? luck/fate :D

The creature is known as a triop, one of those novelty creatures that you can buy in packets that live for a few weeks. On the packet it says they lived alongside dinosaurs, which is true. The reason why they have survived in the deserts of Earths past is because they lay their eggs, and then bury themselves in sand in search for more water after the #39;pond#39; dries up. The eggs, just layed, will lie dormant untill water reaches them. So the reason for them being discovered on top of Uluru is most probably because they are related to previous triops that layed their eggs ontop of Uluru millions of years ago when Uluru was at ground level. Overtime the triops hatched, layed their eggs and died leaving another generation, to hatch. Over time this will leave some eggs on top of Uluru ready to be hatched when water hits them.
