    Cuyahoga County stream bed find.  Matrix brushed away.  Post glacial (rounded) Canadian pebble?  Ohio couldn’t have rounded and smoothed it and left a fossil on its surface, right?

    @greg-kessinger  Canadian pebble is probable.  The material on the surface would not have survived the glacial action that rounded the pebble.  My thought is that this is a post glacial mineralogic creation, perhaps caliche?

    From my own experience, I have a small pebble that I found as a kid that was split in two with both sides together.  It is red sandstone (?) and inside is the impression of a Devonian brachiopod.  So this one made it from Canada to Dayton, Ohio.

    The other improbable specimen was found by a fellow Dry Dredger here in Cincinnati.  This was a small slab with a complete well preserved Devonian Phacops trilobite from the Toledo, Ohio area.  How that survived is unimaginable.
