Rockwood Posted February 25, 2017 Share Posted February 25, 2017 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.

Rockwood Posted February 26, 2017 Author Share Posted February 26, 2017 Could these be root casts that were formed in the paleosol of a Pleistocene interglacial ? Link to comment Share on other sites More sharing options...
EMP Posted February 26, 2017 Share Posted February 26, 2017 Definitely not lower Devonian, seeing as though this would be a vascular plant. I don't know, looks like a rock to me. Link to comment Share on other sites More sharing options...
Rockwood Posted February 27, 2017 Author Share Posted February 27, 2017 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.
