What do you guys think.
These are heavy. Together they weigh 1lb. Some of my favorite rocks.
Pics show the top, the bottom is black and indented like it was sinking into the bedrock.
My gut tells me it's flint with chalk coating. Yes? No? Any ideas.
From the pictures I would guess some sort of iron stone weathering on the outside to limonite.

The bottom shows evidence of it sinking into the bedrock almost like clay.
That wouldn't be Creation Clay would it?
