The Lost World of Fossil Lake: Snapshots from Deep Time

Lance Grande

The landscape of southwestern Wyoming around the ghost town of Fossil is beautiful but harsh; a dry, high mountain desert with cool nights and long, cold winters inhabited by a sparse mountain desert community. But during the early Eocene, more than fifty million years ago, it was a subtropical lake, surrounded by volcanoes and forests and teeming with life. Buried within the sun-baked limestone is spectacular evidence of the lush vegetation and plentiful fauna of the ancient past, a transitional ecosystem giving us clues to how North America recovered from a great extinction event that wiped out dinosaurs and the majority of all species on the planet. Paleontologists have been conducting excavations at Fossil Butte for more than 150 years, and with The Lost World of Fossil Lake, one of the world’s leading experts on the fossils from this spectacular locality takes readers on a fascinating journey through the history of the discovery and exploration of the site. Deftly mixing incredible color photographs of the remarkable fossils uncovered at the site with an explanation of their evolutionary significance, Grande presents an unprecedented, comprehensive portrait of the site, its treasures, and what we’ve learned from them.
