Rocket6020 Posted September 22, 2018 Share Posted September 22, 2018 Gday all, was wondering if this was an egg or a rock? I found it on a beach in Australia near the border of south Australia and Victoria when I was a kid, I cut it in half and just forgot about it for around 20 years!

Tidgy's Dad Posted September 22, 2018 Share Posted September 22, 2018 It's a very pretty thing. i think it's been cut and polished into the egg shape and the markings inside are dendrites, a manganese mineral.

Rocket6020 Posted September 22, 2018 Author Share Posted September 22, 2018 Maybe? It would have been rolling around in the southern ocean for more than a little while I guess! Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 22, 2018 Share Posted September 22, 2018 I agree - polished stone. No fossil or egg likeness here.

Rocket6020 Posted September 22, 2018 Author Share Posted September 22, 2018 So given that it's a rock does anyone have any idea on the yellow/tan colour in the middle? Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 22, 2018 Share Posted September 22, 2018 Not egg yolk. Original color of the matrix. The darker stuff may have been super heated. Common for metamorphic rocks.

abyssunder Posted September 24, 2018 Share Posted September 24, 2018 It could be also a polished "Thunder Egg" .
