Okay, I concede early on that this may be abiotic, but I just have this gut feeling that it's not an accidental pattern. I found this on the banks of the Potomac River in Virginia. The geology there is mostly early to mid-Miocene clays with a Pleistocene terrestrial bog iron layer on top of 40 to 80 ft cliffs overlooking the river. All fossil-bearing. This looks like clay, but I'm not positive that it is from the Miocene layers. There is a row of tiny lumps all about the same ship and almost in a contiguous line. One is just a little offset. 5c92c79a0adbe_HeatherSiple-stratmystery001.jpg.42d3063c568299b59033ed6d9ddc2a02.jpg5c92c79a5ce06_HeatherSiple-stratmystery002.jpg.0734f525f848ba6d620d3479e5956dde.jpg5c92c79ab6b8b_HeatherSiple-stratmystery003.jpg.322f0822e4e59fe8e04211f251b3a9b5.jpg

I refuse to give up my childish wonder at the world.

Just looks like harder parts of the rock that are more resistant to erosion to me, i'm afraid.

Isn't this the definition of a fossil that has weathered from the matrix? Looks like it may be a fragment of something, but I doubt it could identified unless more of the matrix is removed. Or maybe I'm just completely wrong. Flip a coin. This is one of those I would want to examine in person.

Fossil hunting is easy -- they don't run away when you shoot at them!

No, not really. 

 

I’m with  @Tidgy's Dad this just looks like a rock to me. No obvious fossil here.

I'm sure that spot will produce something better.

Oh, it already has. I just love a good mystery.53618328_390133134899149_6819765547530452992_o.thumb.jpg.55a5c0ed7f66e2fc56b452e7953c17b7.jpg5cadea84bd803_Dolphinandwhale.jpg.b1fdad724c1e065db338f41d31370c3e.jpg5cade5ebcfd4a_whaletoe.jpg.43b7a963ae3c1439a52278b534f18af4.jpg
