Welcome to the Forum. :) 

These look like Orthocone cephalopods to me. 

The first may be a cross section of one, not sure. 

 

Cropped and brightened a bit:

Thank you. I’ll see what I can do on lighting.

One possibility for your first item is a longitudinal section through the "fronds" / whorls that radiate from the spiral axial column of an Archimedes bryozoan.  This would also seem to fit with the geology of your area.  Closer pics might help.

 

Another possibility for your second item is horn coral (Hapsiphyllidae?)

This close-up of the broken edge of your first fossil with the dentate margins seems consistent with Archimedes fronds.  The spaces between the "teeth" are where the fenestrae were.

Here's a link to a picture on the Palaeontology Portal that will help put your specimen in context of a more complete/better-exposed specimen:

Not a bad idea! :)

I wondered if the second specimen was plant material, also. It has a porous look about it like the woody plant material I find at Mazon.

Could we see a side view of the this. If it were to be Cephalopod or Archimedes, the pattern should likely be seen on this side too (unless just an imprint). From this view, I don't see a hint of that being present. I will stick my neck out and say shell material from a brachiopod? Actually an end view of your other specimen would be helpful too.
