Symbols found on multiple rocks

I have a looked at some of my rocks to identify similarities

This last one you posted Tigs looks like it could be quite special, can we have a clearer pic please...

Thanks Tigs, firstly it is a tool, it has sharpening retouch flakes along the bottom edge, worked flint pebbles like this one are reminiscent of olduvai gorge finds, although this one is far more worked, symbolically it is quite tricky to read, seated elephant or more likley mammoth, thumb with nail, and chimp face are the basics it has given up without going to far into details and speculation, yes there is probably a lot more it will give up on further inspection.

This is amazing thanks for that information.I will have to look at the rest of my collection I am pretty sure I have more like this.

Have you got a turntable and a tripod Tigs? This one might roll like some of mine do, given the right shadow conditions, orientation etc...

I see a bird, probly owl, as the whole rock in the last pic.

This is new I can see eyes and a land scape looking out to sea

Definitely a lot of little stuff going on, tough to make out in pic. The eyes have a feline feel to me, not sure though. Nice one.

This is quite a common shape for a figure stone which I have not interpreted much past cloaked figure if turned 90'CCW ,that eye shape at the top is very interesting

Can you see the eyes they are very small
