The Times Union's Paul Grondahl writes about the discovery of the world's oldest forest near the Gilboa Dam in Schoharie County. The fossilized forest, estimated to be 385 million years old, dates from a period marked by the early evolution of trees. Researchers at the New York State Museum were part of a team that made the discovery in the spring of 2010, after working a riverside quarry exposed when the dam was built in the 1920s. The site is located about one-quarter mile below the dam on Schoharie Creek. The forest flourished during the Middle Devonian period, predating the dinosaurs by 160 million years. The discovery included the identification of two new species of prehistoric trees. Read the full story in the Times Union.
