Gary, The Florissant Fossil Beds date from the late Eocene, around 36 million years ago. This post dated the last of the Laramide Orogeny and was in a basically a period of erosion and sedimentation in the area through the onset of post Laramide volcanism in the area. In general the climates was very much wetter and warmer than it is today. Ice ages did not really begin until some fits and starts perhaps 7 million years ago, and the multiple glaciations episodes of the Pleistocene for the last million years.
