Any Geologists or Stone experts here?

Yes Gerry, it is heavy, but usually river worn stone are quite smooth, but the ridges in the stone are quit distinguishing

Only a tick, tick, tick.....ha ha

Obviously a dragon hatching. It needs fire.

Regards

never any shortage of EXPERTS here on the forum Stephen : )))
looks like a fossilised guinea pig turd ...

Hi Warren

It was in flat open pastoral country near some bluebush. It is not located anywhere near a creek or watercourse.

Having a better look on the computer rather than phone screen the probable iron/manganese oxide is a coating . It's also on all sides so probably formed when buried, not on the surface. When looking at these sort of things, the questions that earth scientists ask is whether what they are observing is the result of a contemporary or relict process. These coatings form as the result of alternate weting and drying cycles, wet to reduce and mobilise the iron, dry to precipitate and form the coating. The uneven nature of the coating is interesting. As I wrote I only associated with the geologists/soil scientists. I can explain what happens once the chemistry kicks in, but only learnt enough to put this in context with the other landscape processes. Swamps I'm the full bottle, but in the arid zone I'm a tourist.

Looks to me like a fossilised turd ;=))

That would be a coprolite, those palentologists have a name for everything ; )

Hi Garry

I have sent off photos to the Museum in Adelaide, so it will be interesting to see what they have to say.
