Just Rocks or Fossils?

[Rockpit]

I found some what I think are rocks at Mazonia that have interesting patterns.  They feel gritty like sandstone but I have never seen it with these patterns.  Is this a type of sandstone?  Could they be fossils?  The last two are opposite sides of the same sample.

Hello, 

These look like geologically created structures, to me. 

I am far from an expert in fossils from your area, however, so wait for a few local opinions.
