None whatsoever - but definitely something
I 100% urge you to literally take that stone, and bring it to your local natural history museum, and see if they are interested.
They will be interested in exact provenance first and foremost - the *exact* location where you found it!
If you don't wanna pester your local museum front desk staff, see if you can email or even phone-call them - it might be a bit awkward, but they usually appreciate this sort of contact highly!
A lot of specimens are brought in by random pedestrians - in fact, they often depend on the public reporting finds to them, since they can't be everywhere!
If you're lucky, you found something
If you're luckier, you got something unique
If you're the luckiest of boys, they might name it after you
Seriously though, check whatever geology/natural history/university-type institutions you have nearby, mail or call them, and show them the rock or the photo - even if it's nothing! Tell us whatever you find out next
