In 1835, Charles Darwin discovered a petrified forest in Auga de la Zorra, Argentina. His discoveries made him question the origin of species. He later recorded his observations in “A Naturalist Voyage (1845)”. Thus, the discovery of fossil forests may have been one of the driving factors for Darwin’s theory of evolution by natural selection. The ancient forest (237-242 million years old) was interpreted to be a subtropical dry seasonal forest and is now known as the “Darwin Forest” (Dr. Telmo Pievant et al., 2009).
