Help me name the outstanding fossil deposits of the midcontinent Devonian

[pefty]

Crowdsourcing / help request!

 

I'm putting together a review article for the fossil collector community on the Devonian rocks of the American midcontinent, which I've defined as the gray area on the map below plus southwest Ontario. I'm hoping to include a section in which I highlight the midcontinent fossils of greatest renown for each of a number of taxa (list below). (I purposely leave "renown" as a somewhat squishy quality open to multiple interpretations.)

 

I would appreciate

(1) your nominations of any midcontinent Devonian fossils of great renown that I have failed to capture in the list below and

(2) your assistance in filling in the blanks marked with "????"

 

Thank you! List is below.
