If you could travel back in time 4.5 million years, how different would the flora look in your area? That is a difficult question to answer because we don't know of many fossil beds that capture this time period. That is one of the reasons the Gray Fossil Site in Tennessee is so amazing. Join me and Paleobotanist Dr. Liz Hermsen for a discussion about some of the amazing discoveries she and her colleagues are making from this unique paleontological gold mine.
