Mini slab with macro fossils, maybe?

[Bradley Flynn]

I have this little slap I polished a awhile ago, it has some really interesting critters on it. Even a micro jaw bone with teeth maybe? Has many interesting things on it, I have just taken pictures of a few. Green arrows point out the "jaw" and a few other things. The "jaw" is the biggest at a whopping 40mm.

I see fragments of brachiopod shell and some crinoid stem columnals. 

Interesting piece, I'd be peeking at it for hours with my loupe and microscope.

Looks like crinoidal limestone with a few other things mixed in.

Nice! Thank!was wondering if I could expose these fossils a little more without damaging them and possibly exposing some hidden macros?

Anybody know if the second and fourth close ups are pictures of a possible jaw bone? Fourth close up has a disc with a hole and two serrated edges running parallel to each other, Ancient Aliens or what?  pic below.

It's a cross section through a crinoid stem. This sort of thing - if worn a bit obliquely across the surface so as to go right through one of the discs on each side, the radial grooves will produce a straight row in section (red line).
