Can anyone help with these symbols

[Bumblinghunter]

While i was out and about, i came across these two rocks that look like they were worked by someone. I have some ideas as to what they could be, just wondering if anyone with a more experienced eye could weigh in. Any advice appreciated, thanks

What about all the other sharp angular rocks in photo one. Were they also worked? Natural broken rock, IMO.

The other rocks were just in the area, not sure if they were worked, possibly. And I’m not sure what IMO stands for, I’m not really big on communication threw technology

 

[Kray Gelder]

IMO...in my opinion.

Just rocks, no symbols.
