Back to the Garden 3

I tagged this photograph with “lichen,” but I’m not really certain that the white marks on the large rock are lichens. What else could they be? Fossils in the stone?

Later in the Day

Scientist-husband David suggests “mineralized inclusions in the rock. Could be of biological or abiotic origin from what little I can see.”

Evening Update

We now have two more opinions favoring the lichen theory: One is from my husband’s colleague in the Oberlin College Department of Biology, and one is from Art Murphy, who usually knows a fossil when he sees one. (See Art and Fossils.)

Now that we’ve moved back to Oberlin, I don’t go to Schoepfle Garden as often as I used to when it was a half-hour’s walk from home. I was there twice last month, though. I love to get there early.
