Directions:
The site is on the east side of Murfreesboro Pike between the interstate and Plus Park Blvd.  Park in the gas station parking lot and walk south toward the bus stop.  To get to this site you will have to climb down into the gully next to the road and then up a bit on to the exposure.  Because it is on a major street, the site has a good deal of broken glass.  It also is overgrown during the growing season and has cactus growing right where you want to lay your hand down.
 

Why go to this site:
This is the best site in town to see the boundary between the Stones River Group and the Nashville Group (the Upper Carters member of the Carters Limestone and the Curdsville member of the Hermitage Formation).  It is also the best place in town to find Upper Carters and Curdsville fossils.
 

What you will see:
The Upper Carters member consists of very white thinly bedded limestone mud alternating with thin layers of limestone sand.  The limestone mud has very few fossils, but the limestone sand is filled with fossils, mostly ribbony bryozoans and crinoids.
 

This is a typical piece of Upper Carters Limestone found at  the Plus Park site.  The thin (~1mm) layer of limestone sand in the center is filled with crinoid stems and ribbony bryozoans.  The white limestone mud unterneath it (top and bottom) has only trace fossils.

The Curdsville member of the Hermitage Formation which lies above Upper Carters is very fossiiferous shaley limestone. Slabs containing dozens or even hundreds of fossils are common at this site.  The fossils of the Hermitage Formation are very distinctive, markedly different from the fossils found above and below it.
 

The commonest brachiopod is called Resserella. The species found here is appropriately named fertilis. It appears to have multiplied wildly and formed huge groups.	The commonest bivalve mollusk is Ctenodona.  In Nashville, bivalve mollusks are almost all internal molds.  There is another larger species of mollusk found here which I have not identified.
The bryozoan Prasopora started its colony encrusting on the shell of a Resserella or a Ctenodonta and then grew to be a great deal larger.  On the top view (left) you can just barely see the dots which are the holes for the individual zoids.  On the bottom view (right) you can see the imprint (external mold) of the Ctenodonta on which the colony grew.	Atactoporella is an encrusting bryozoan which grew on the shell of a small snail.  This bryozoan was so common that it covered the shell of nearly every snail in the area.  In all of my hunting in the Curdsville, member, I have only found one snail shell which was not covered with Atactoporella
