Would love some IDs on these. I could take a stab at it from this page of Robert Sloan's book, but would like other eyes on these. I believe both are complete, what do you think?

 

Thanks for looking!  :-D

First one looks like flexicalymene.thumb.jpg.15f26c8d8a69c7c7e3711b192fb04a48.jpg

The second one is enrolled and cant make out the cephalon or pygidium.

I second that the first one is a Flexi. You might need to prep the second one a bit more to obtain a bit more detail.

The other one is a ceraurid.  Here is an illustration listing the anatomical features.

Thank you so much Piranha!

 

So the full creature would look something akin to this...
