There is an interesting new paper in Quaternary Science Reviews. It is:
Spencer, J., Jones, K.B., Gamble, D.W., Benedetti, M.M., Taylor, A.K. and Lane, C.S., 2017. Late-Quaternary records of vegetation and fire in southeastern North Carolina from Jones Lake and Singletary Lake. Quaternary Science Reviews, 174, pp. 33-53. http://www.sciencedirect.com/science/article/pii/S0277379117303141 In part the abstract reads; "We conducted fossil pollen, charcoal, and geochemical analyses of sediment cores from Jones Lake and Singletary Lake spanning the last ∼50,000 cal yr BP to examine the linkages between climate, vegetation, and fire activity on the Atlantic Coastal Plain, and particularly emphasize changes since the Last Glacial Maximum." There are two interesting aspects of these cores. 1. Nothing special occurs at the beginning of the Younger Dryas in terms of either changes in lithology, vegetation, or charcoal influx. 2. The sedimentary and palynological records in both bays extend past the beginning of the Younger Dryas at least to circa 50,000 years ago. Thus, contrary to the model of Antonio Zamora, both of these Carolina Bays are significantly older then beginning of the Younger Dryas. This raises some obvious problems with his ideas. In addition, there is complete lack of any abrupt changes in sedimentation or flora at the beginning of the Younger Dryas that a person would expect to accompany a truly catastrophic extraterrestrial event capable of causing a mass extinction. Just some thoughts. Yours, Paul H.
