Oklahoma trilobite experts needed

[Perfect Castaway]

I had some rock left over from a trip to Oklahoma a few years ago and finally decided to take a hammer to it to see if I could find anything and, well, I found this guy. Pretty sure it's a trilobite, just wondering about the species. Looks to my untrained eye to be a phacopid. Not sure about which one, or even the orientation inside the rock. Haragan formation.  Any ideas?

I think @Kane and @LordTrilobite will be able to help.

Judging by the shape, it may be Kainops raymondi, but that is a guess based solely on the outline. From what I have heard from others, it is not uncommon that trilobites from that formation may appear as "hairlines" and tend to shear through requiring being glued together and prepared in a manner similar to that of Devonian trilobites in Morocco. 

 

It might be more advantageous if we get @piranha's expertise on this one.

 

If I had to play with this one, I might remove the matrix in yellow to reveal some diagnostic details:

Thanks, I should have mentioned that I intend to glue it back together and prep it out. I just want to make sure I'm hitting it from the right angle.

I agree they are phacopids.  Here is a similar cross-section example from:
