The Cairo Fossil Forest in New York, discovered in 2009 and announced in 2019, contains 385 million-year-old trees from the Devonian period, representing some of the oldest trees with leaves and woody trunks, and providing insights into early forest evolution and Earth's atmospheric changes.
Fossilized tree roots from a 385 million-year-old forest in New York's Catskill mountain range provide insights into the origins and evolution of woody deciduous trees. Belonging to the genus Archaeopteris, these roots resemble modern-day forests and demonstrate that trees developed the strategy of roots early on and have maintained it until today. Unlike other plants at the time, Archaeopteris had sturdy and intricate root systems that allowed for efficient water and nutrient absorption. This ancient tree ancestor had a large trunk, broad leaves, and a serious metabolic engine. The discovery sheds light on the impact of trees on the Earth's environment and the reverse effect of deforestation.
