> Tony, et al.: You're right that in western Georgia the Providence SS represents the latest Maastrichtian and is unconformably overlain by the Clayton LS, which is early Paleocene: hence, we imply a hiatus. However, I'm not convinced there isn't some locality where they are conformable and where the K/T boundary is present: I'm finding that the latest Providence age and earliest Clayton are nearly contemporary. It also makes paleoecological and physical sence for them to be penecontemporaneous. David Schwimmer Hey Dave - I was wondering if you were lurking out there and hoping that you would interject with something beyond my limited experience with the K/T boundary in Georgia. I wouldn't be surprised that a conformable boundary is somewhere in western Georgia, buried beneath the kudzu. (Kudzu, for those of you who have not visited the southeastern U.S., is a creeping vine that covers entire outcrops in a matter of days, it seems; it is one of the few plants that cause geologists here to support the use of Agent Orange.) Nevertheless, it would be pretty exciting news if you can find it. What evidence are you finding for a penecontemporaneous boundary? Has the vertebrate material coming from the Providence and Clayton helped with the resolution of the boundary? Any trace fossils that transect what you're interpreting as the boundary? Inquiring minds want to know (and I'm sure that mine isn't the only one here that's inquiring)... Anthony J.
