There it occurs as a bed that is shale- bounded in places, overlies the Noix along an irregular contact, is overlain by the Bowling Green Dolomite along an undulator>' surface, and pinches out north- ward along the exposure (Text-figs. 5. 6). This bed is assigned to the Kissenger. The coral-rich interval of the Kissenger Limestone contains solitary rugosan coralla that are abraded, have algal coatmgs, and have microborings of probable algal origin associated with micritized surfaces. We consider it to be a lag deposit that is likely isochronous. Slrep- telasnia suhregu/arc (Saxage. 1913b), the only solitary rugosan species in the interval, also occurs in the un- named member as well as other strata included in the Kissenger Limestone Member of the Bryant Knob For- mation. The solitary coral assemblage in the basal Bowling Green Dolomite at Section 17 (Clarksville), both above and lateral to the coral-rich bed, is entirely different. We infer that the unnamed member of the Bryant Knob is older than the Kissenger Limestone Member, which in turn is older than the Bowling Green Dolomite. This interpretation, based on the distribution of sol- itary Rugosa, is consistent with the nature of contacts between the various units in this sequence. Where the unnamed member of the Bryant Knob Formation is present { Section 18), it overlies the Noix Lime- stone with apparent conformity (Thompson and Sat- terfield, 1975, p. 103). Where the coral-rich interval at the base of the Kissenger Limestone Member of the Bryant Knob overlies the Noix, the contact is uncon- formable (Section 17). The contact between the Kis- senger Limestone and Bowling Green Dolomite is un- conformable at some sections { Sections 17, 18; see Thompson and Satterfield, 1975, pp. 98, 103). We conclude that both members of the Bryant Knob For- mation as well as the Bowling Green Dol
