Vt fossils

[Jazfossilator]

Got out for the first time this year to one of my favorite spots on Lake Champlain. Came home with a grocery bag full of rocks. 

tons of crinoid bits and pieces as usual, some bryozoa pieces and some brachiopods. Any info on these would be much appreciated! (Iberville formation-Ordovician) these fossils are very small so I’ve tried taking pictures through a magnifying lense to show detail, if more are required of any given piece just ask!

Number 5 looks like a piece of conulariid, but I'm having a hard time interpreting it's orientation to fit the shape (four-sided / "pyramidal"), unless it's axially flattened. 

 

 

Here's a piece I found in the Mississippian

I found another similar thing on the same rock, thanks for the response

You must work at Kmart, cause you love your Blue Light specials!

It could be ornamentation on a brachiopod, too.  But that black color made me think phosphatic.

It’s the light attached to the magnifying lense

#3 may be a blastiod.

The last picture is a trilobite fragment - cross section of pleura.

I found others like this in a more Uniform shape, is there a reason that this part of the trilo would preserve more often than others parts? Thank you!

When I find pieces like that, I assume it was a high energy environment that may have broken up the molted shells of the trilobites. 

Many of these areas you can mostly find pieces, numerous cephalons, or pygidiums, depending on how the currents winnowed them and deposited them , usually by weight, I would think.

#5 is a plate from a cystoid along the lines of Glyptocystites/Homocystites/Cheirocystites.  The horizontal lines are part of the pore rhombs, which were resiratory structures.

This one, and the next look like a chaetetid or a bryozoan like my Monotyypa, also Ordovician
