Loose on the cobble near the mudflats/water at Blue Beach, Nova Scotia.  Just wondering if this is textured rock or any kind of fossil. Thanks for your help with this.  Cheers

Probably ripple marks with  Kinneyia (microbial mat)

@wyldewastelander , I do not know the geology of your region, do you know the geological period for your rock? did you find only this specimen , or is this rock found in layers visible in the surrounding area?  ( thank you for your reply )

Hi there @marguy. I am not really sure of the geological period for the rock.  I am only suggesting Carboniferous because that's my understanding of the geological period for the significant fossil finds of the area.  I observed this one specimen - it was loose on the rocky area of the beach.

Tool marks are common there, so ripples might be expected. A feature that I questioned about being microbial, turned out to be a settling/dewatering feature. 

There are plant fossils as well as plant and animal traces, so a thin organic layer of muddy surface that puckered some makes sense to me. A thick mat, in human terms, would likely preserve on a microscopic scale if at all.
