Cambrian Shady Dolomite east of Cartersville

So I've been reading some bulletins recently looking for a new place to hit when I came across this interesting section in bulletin 54 (https://epd.georgia.gov/document/publication/b-54-geology-and-mineral-resources-paleozoic-area-northwest-georgia-1948/download):

I've heard of the Archeocyathus from the Georgia fossils website and that they're Georgia's oldest fossils coming in at ~516 MYO. What I didn't hear about, however, was this:

Trilobites? More importantly, Wanneria??? For reference, here's the bug in question:

It's safe to say that I've never heard of the whole trilobite part about these rocks. Anyone with additional info about this?

The Shady Dolomite in Georgia only has Wanneria fragments according to Resser 1938:

 

Shady Dolomite — ...Archaeocyathid reefs are beautifully developed in the vicinity of Austinville (Plate 1), and Archaeocyathinae are known from Georgia and Virginia. They may be expected anywhere in the formation. In Virginia and Maryland fragmentary fossils indicate the presence of Kutorgina, Salterella, and olenellid trilobites. A very large species of Hyolithes, fragments of Wanneria, and poorly preserved brachiopods occur in reefs in northern Georgia.

I'm a bit confused.  Is the trilobite in the photo from Georgia, and is it from the Shady?  What is the source of the photo?  I have heard of whole olenellids being found (rarely) in the Rome Formation but not the Shady.
