No clue what it is.
From the thumbnail I thought you posted bear scat.

Thanks GALLA.

Nidularia is a really interesting proposal. The surface of each nugget looks a lot like the “egg mass” of N. deformis. But according to the info I have found, N. deformis is sheathed by a cup-like base, and the eggs spill out at maturity. So if this is N. deformis, then some sort of unusual development must have contributed to the egg mass remaining intact and hardening over time.

Walt, I see you have weighed in on this one. Are you familiar with Nidularia?

is black inside, without the appearance of the slightly raised polygonal plates as seen coating the surface. But with the loupe, I did notice a few concave polygonal imprints within the interior.

I think Phil is probably correct about this, with the polygonal plates representing fossilized seeds.

What does the context look like?

Phil, this sounds like a good posibility.

I suppose some small animal may have eaten blackberries, or another types of berry with large hard seeds, and the result was a skat that did not deteriorate. These objects are hard, like roughened pebbles.
