States (in the U.S.) Where Trilobites Have and have not been Found

Here is a more comprehensive list of North Dakota Trilobites from lower Ordovician drill cores:

At long last......the 10 year old link is broken no more!

 

Hooray! Cheers bud!

Rare trilobites have been found in Citronelle chert gravels of Thompson Creek, West Feliciana Parish, and rest of eastern Louisiana. A Louisiana trilobite can be found in the last page of "Fossil Hunting in Louisiana Gravels" by Dr. J. Schiebout and others. These chert gravels came down the paleo-Tennessee when it emptied directly into the Gulf of Mexico from the Nashville Dome.

Possible I suppose but highly unlikely.  The few trilobites from South Carolina came from a very localized area within a highly deformed schist formation, where the rock was not quite as deformed and metamorphosed.  The equivalent formation in North Carolina is even more metamorphosed.  The main South Carolina site was a very small roadcut, mostly exposed in a ditch on a very small road near Batesburg.  I visited the site a few years ago and and found no trace of the roadcut remaining.  Other localities in the area consisted of erratic boulders, not actual bedrock exposures.

It's possible NC has some out west. The Chilhowee Group has produced trilobites very close to the NC border in Tennessee, Georgia, and Virginia, but granted most of those were on the western side of the Blue Ridge. I believe the Chilhowee does outcrop in NC, but haven't heard much about it. The Wilhite Formation in far eastern TN has also produced trilobites, and I believe that formation may be exposed in parts of western NC, but I'm not entirely sure on that.

If you want NC trilobites, this sounds like the formation to go looking for.
