Moscow fm. boulder fossils

[SharkySarah]

These are from large rocks I found in Erie co NY. I would love second opinions on my ID and any tips for pyrite. 

 

2. Some kind of coral or bryozoan 

 

3. Crinoid column 

 

 

4 A and 4 B. Greenops?

 

 

 

4c. some shell matter, something unknown and a crinoid 

 

11. A large rugosa coral?

4 are likely both Eldredgeops rana. 4a is a bit too weathered to confidently tell, but 4b is definitely Eldredgeops.
