January 24: Fossil squiggles

[neverspent]

Rocks are so amazing, and I understand so little about them. My most recent find, back at the farm, was a piece of gray sandstone, bigger than my hand and fairly heavy, with one broad flat surface. That surface was a dark red or burgundy color, mottled with light orange and tan squiggles. The squiggles really make me think of worm castings. But all this patterning on the surface of the stone is mineral, some of it even formed of tiny crystals. So it could be fossilized evidence of worm activity, but I just don't know!



In this picture you can see how thin the layer is.
