Here are the best prep results from a trade with Misha.  Second & 3rd images:  Back row, left specimen, Greenops boothi.

In front of it, cephalon of Eldredgeops rana.  Front specimen, pygidium (will try to identify later). Second row:  brachiopods, one on left, Spinatrypta spinosa (renamed, will add new name to thread later on).  The rest, thorax assemblages. Unfortunately, I couldn't get any of them to fit together.

First image:  rugose horn corals, other side of Spinatrypta brach.  I will add the finest specimen in a reply to this post.  Ran out of photo room.1596851262755-336587389.thumb.jpg.d12decf912789ccfab23163847be0247.jpg

Here is the finest specimen, an Eldredgeops cephalon sitting atop a rugose horn coral, several views.  Preparation is not complete on this one, as matrix still needs to be removed from between nodes on cephalon and lenses on eyes.  Photos in next reply.

One last set of photos.  Was having troubles getting photos to load.  The coral side of things. Strangely, ther1596854192315-710349244.thumb.jpg.34ed0ad55be76a1fe34e9ff4988b4fa9.jpg1596854192315-710349244.thumb.jpg.34ed0ad55be76a1fe34e9ff4988b4fa9.jpge is a tubular item stuck in one end, just filled with crystals?  Large bryozoan?

In Part E (Evolution) of this course, attention is given to Spinayrypta spinosa, Tropidoleptus carinatus, and Pseudoatrypta devonica.  I cannot, otherwise, find Spinatrypta anywhere on the web, so I can only presume its name has been changed, perhaps related to the other two mentioned in the course?

 

Here are some better photos to help figure it out with.

As for the pygidium, I think it belongs to an Eldredgeops, but I am no expert.

Looks like Pseudoatrypa to me

I think that this is most likely, crystals. I have a few pieces that contain some really nice ones inside the corals

 

Also, one of the pictures you sent me has a G. boothi cephalon from Penn Dixie, I don't see it here but it is a nice piece.

Ok, other cephalon pieces maybe not shown before.  Also upon review of the original post1596862479100657388360.thumb.jpg.72e8c500f5627fd5401614c794da2744.jpg, I notice that the photos are in mixed order from what the text indicates.  No idea how that happened.
