Rock with plant "drawings"

[ianelli]

Hi! I've found that rock on a cliff near some fisherman houses by a beach here from my town. There are some vulcanic rocks on the area too. 

Here are some pictures of the rock.
I found those "plant marks" strange. Could that be a fossil?

Nice find!

Those are a mineral growth call dendrites. They are typical of manganese crystallization.
