Is this a tetrapod trackway?

My father pointed this possible trackway on a sandstone paving stone on his front walk.  I don't know the source of the rock.

 

It looks clearer in person than on the images.

 

There are several possible tracks in sequence- I took a picture of the only one that looks mostly complete (last image, with quarter).

 

Other pavers in the path have odd marks that look sort of like drag marks from vegetation, bubbles, or worm or crab tracks. (not pictured on this post).

 

What do you all think?

It does look like a footprint. I don’t know where the sandstone pieces are from. You might go to a local stone seller to see if they know the formation and age. 
 

Here in Arizona, the most common flagstone is from the Coconino Formation. I have seen footprints in slabs in a person’s patio.

Very iffy. 

Usually you would see more in the way of nearby traces.

I does look like a footprint. 

But that's where pareidolia comes in. 

I would be hoping it was a footprint myself, but also aware that this is quite unlikely as it doesn't seem complete, there are no others and they're pretty rare. 

Probably, but not certainly, just marks on a rock.

possibly an underprint of a footprint. and I do see a second one on the surface.
