Just a pattern in the rock, or a fossil?
We visited Fossils Cliff in Collier Township on Sunday, the limestone layers in the valley the ideal for finding impressions of archaic living beings between the layers. Sometimes the patterns were clearly just a pattern of the layers settling against each other, but other patterns clearly looked organic. This, to me, looks like a spine and perhaps even ribs. It’s about 12″ long and on the underside of an outcrop, impossible to take away.
I came home with a pocket full of smaller possibilities.
Below is a photo of the cliff with my niece and her children and Bingo the dog at the bottom, to give a sense of scale. It is easily three times wider than this, and between visitors and natural rock activity pieces of limestone are constantly falling. The fossil above is right about the center of this photo, on the shadowed outcrop right above the top of the loose limestone. We could only step around on this loose limestone, no climbing for us!
