Notes:
We know of these forests because of the splendid sample of fossil seeds, nuts, fruits, leaves, branches, and roots. The Clarno locality is one of the finest fossil plant localities on the planet, with hundreds of species, many new to science, preserved. The Nutbeds were formed as a delta in a lake. Because of the variety of plants fossilized we have a very detailed look at the ancient environment and make assumptions about the climate.
