A dry patch of high desert today, Fossil Lake is what remains of three huge lakes that spread across what is now Utah, Wyoming, and Colorado some 50 million years ago. The place is rich in fossil remains of subtropical plants and animals remarkably well preserved across eons of time.
This book documents the immense formations which captured in fossilized form a moment in the early Eocene period 55 millions years ago. It was a time when the North America continent was primarily subtropical, warmer and far more humid than today.
The author explains of how the fossil lake system was formed, what flora and fauna thrived and died within it's waters, and how they were preserved for mankind to discover and interpret.
