Hello everyone,
I'm a collector of all sorts of things, I use to love hunting for shells and fossils near the ocean as a kid. I was going through my old collection and I found this interesting rock that I hope someone can help me ID.
The specimen was found on a beach on an Island in Greece over 20+ years ago. It's got some naturally occurring shapes and letters, almost like an abstract painting on the one side and a signature on the other side. Nothing has been done to it, as found.
My guesses......ancient ball of clay with some sort of plant life in it? Septarian Nodule? A little stumped so hoping someone can help out.
