Interesting piece, kind of looks like a claystone. How hard is it?

 

[Nugget]

Looks like a nice piece of white fudge

Could it be bone or ceramic?

 

[Martin]

White quartz?

 

[casper]

Looks very much like some fossilized wood i picked up on the Mornington Peninsula

 

[Colin&Lee]

Chert maybe?

Cheers

Possibly Flint , as in ancient spears ...etc....

It's really hard to scratch the white stuff on it scratches quite easy.

 

[Dughug]

Like Colin&Lee I'm inclined to think that it is chert.

 

[SWright]

Yep, I would say its chert. It has the concoidal fracture lines of quartz which means its probably the same compositiion and the only rock I can think of that would fit is chert.

Thanks guys I only picked it up becaus it was totally different from any other rocks I could see, stuck out like a sore thumb

 

[RedDirtDigger]

Almost 100% certain it is a waste flake of chert from stone tool making.

 

[Palmer9999]

It looks like Gold to me, Jokes. Probably chert.

[Bigjilm]

It's quite big maybe as big as a golfball

Hi Bigjilm, I have recorded many aboriginal sites and scatters of flaked stone. I can see an unmistakable bulb of percussion mark where one flake was hammered off your stone and faces where other flakes have been hit off. If its golf ball sized it is the left over core after all the flakes have been hammered off. When the rock being worked gets down to about that size it gets difficult to hammer off the desired flakes and the core is discarded. The rock looks a little worn and varnished so I think the stone was probably worked a couple thousand years ago at least

So in my humble opinion i'm pretty sure you have a aboriginal core

The raw material is probably chert but could be a form of chalcedony also.

Hi bigjilm great find looks like a fossilized bone,they still find fossils in the otways today some parts of the otways are still closed today due to finding fossills that date back millions of years.maybe yours come in from the heads with the currents great find anyway enjoy :lol:

 

[PhatGeology]

looks real cool, ill be up there tomorrow for a bit of looking around and a camp from Adelaide great find there

 

[AtomRat]

Its not an opalite of some sort is? I remember throwing a massive chunk of chert back into the creek one day

 

[DrDuck]

Chert was my immediate thought, like those others who have commented before me....

It's a microlith, made from chert, some Old Fella used it as a fabricator.

The photo attached is a burin (awl), used to drill holes in tanned leather, or a piece of wood to drill a hole in a bullroarer - about the size of my thumbnail and discarded when it got too small to re-point it
