roots ?

[Rockwood]

First trip of the year. Top rim of the gravel pit.

Things here are typically lower Devonian and below. Most of it is marine, but plant fossils are found north of here.

The closest I come to recognizing the matrix is the volcanic (ash) west side of the Lobster Lake formation.

Could these be root casts that were formed in the paleosol of a Pleistocene interglacial ?

Definitely not lower Devonian, seeing as though this would be a vascular plant.

 

I don't know, looks like a rock to me.

Perhaps I wasn't clear. My thought is that the stone, as such, was part of a paleosol when the roots etched into it. Frozen conditions could have provided the time for them to become mineral replacements and afforded protection enough for them to survive the final deposition.
