Tens of millions of years ago volcanoes erupted in Colorado, fossilizing animals such as insects, fish, and mammals in the same deposits as flowers, trees, and the delicate leaves of plants. This collection of animals and plants from the same place at the same time provides a rare, uniquely comprehensive view of life at this time. Herbert Meyer brings the fossils of Florissant to life using more than 200 colour photographs and vivid descriptions. He provides background on the plants and animals as well as exploring the warm environment in which they lived.
