Yeah its a odd one but I have found some fossils at point danger Torquay way back when I done a lot of surfing. Its definitely eggs in the rock, 3 eggs and one not formed well they look like eggs lol
Next time Im out that way I will take some pics.
And if anyone is interested and your out great ocean rd way stop at bells beach. Some of the cliff has collapsed but u need to park at Southside car park to get down.
You will see fossilised shells and other strange looking shapes in the rock.
Bigwave might know about it as his done a bit of surfing down that way.
