@CiaraNi @JustFi maybe not so far off. We get beautiful little creations washed up on the shores of Lake Erie sometimes. In many cases I think they are man-made agglomerations, like brick veneer with mortar or pebbles embedded in concrete. After they are smoothed by a few years in the water, they can be the coolest things ever (IMO).

So maybe you personally didn't make this, but your species might have.

@CiaraNi There was a time when we measured people by rocks.

He's 12 stone. She's 10 stone.

@ShadowInTheVoid @NormanDunbar I was struck by the apparently clear divide between the black and white halves, as if they had been used by some amazing process or force. One half being a 'coating' over the other is probably more likely.

'I am also not a rockologist nor do I play one on TV though I did once play one in a drama class at school.' :-)

As you played one in drama class at school, I am going to accept anything you say about this rock and any other rock.

I couldn’t quite remember what they’re called so I searched “walking rocks” and got there immediately 😂
