Are theses imprint of feathery pinnules of a crinoid or graptolite ?

Are these partial imprints of crinoid feathery pinnules?

 

Sorry for the bad photos, the plate is small and monochrome.

These look like graptolite imprints.

Thanks @Fossildude19, if this is a graptolite imprint, then it's the first one I've found. 

There seems to be something else in the top right corner, do you know what it is ?

Looks like a cephalopod, possibly with some sort of epibiont encrusting it.

I picked up this small dark, ordinary plate for the crinoid segments, but now it is quickly becoming one of the most interesting fossils in my collection with graptolite, a cephalopod, with maybe some sort of intriguing epibiont encrusting it.  

 

Thanks!
