A rock with a lot of life in it

[Ralenka]

Hi! 
Found this interesting rock on my walk today with a lot of remains. Sone of them I can try to ID (I see lots of crinoids), but there is also new staff. 
location: Tompkins county, NY, USA

period: Devonian

size:1-2 cm

Rock compositions: shale with layers of remains-rich material
 

Items of interest: On the last picture what are the comb-like structure and two things that remind me of sea acorn? Thank you!

Your second to last picture shows crinoidal limestone. 

The last pictures are rugose corals, and possibly a Pleurodictyum or Favosites type coral.
