Curious Caps watercolor painting

An ancient carving sits on a bed of moss, surrounded by seemingly curious caps of mushrooms. Has it recently been unearthed, or has it somehow sat unmoved for millennia?

This is a 3.5" x 3.5" original piece on 140lb Arches watercolor paper. Created in watercolor, pen, pencil, colored pencil and gouache by Michael Phipps.
