I saw this potential fossil in the Jurassic age Navajo Sandstone in Zion National Park in Utah. I'm sorry that there is only one picture with no scale. I was hurrying down the precarious Angel's Landing trail with a long line of people behind me, so I only had time for a quick picture. The feature is probably about ~12 inches long, and I believe that it is situated on the plane of a cross-bed in a dune structure (example of the cross-bedded sandstone is also pictured). This feature might just be some sort of iron precipitation, but it looked so similar to an invertebrate trace fossil that I am not sure. Any thoughts on what it could be?
