Paleoenvironmental Change and Megafaunal Extinction at Page-Ladson, Florida
Author(s): Angelina Perrotti; Jessi Halligan; Michael Waters

Summary
Sporormiella sp. is a coprophilous fungi associated with large herbivore dung that can be used as a proxy to track megafaunal extinctions. The data is based on its abundance or absence within dated sediments, which is often presented as a percentage related to the total pollen sum. This poster presents the results of a fossil pollen and Sporomiella analysis from a sediment core extracted from the Page-Ladson Site, located in a sinkhole in the Aucilla River, Florida. The 5 meter core spans the Pleistocene-Holocene boundary and most of the Holocene. The types and percentages of fossil pollen combined with the presence/absence of various percentages of Sporormiella sp. provide a unique window into the timing and possible causes of megafaunal extinctions in that region of Florida.
