The Carters Limestone is a geologic formation in Tennessee. It preserves fossils dating back to the Ordovician period. [1] [2] [3] The Carters contains abundant invertebrate fossils, including corals, stromatoporoids, brachiopods and bryozoans, mollusk (gastropods, bivalves and orthoconic cephalopods) and trilobites. Trace fossils also occur.
The Douglas Lake Member is composed of a diverse set of sedimentary rocks, including rubble conglomerate, chert conglomerate, and black dolomite.In outcrops along the north shore of Lake Douglas, the chert conglomerate overlies the rubble conglomerate and both of which fill prehistoric sinkholes, called paleokarst, developed in upper surface of the Mascot Dolomite.
Notable fossils from this formation is the gastropod Turritella, the bivalve Pterotrigonia thoracica (the state fossil of Tennessee), as well as other fossils such as crabs. It is alternately considered its own geologic formation (as the Coon Creek Formation) or a distinct member of the wider Ripley Formation (as the Coon Creek Member or the ...
