This fossil of a liana gives evidence that modern-type rainforests may have been around as early as 80 million years ago. The stone had been unearthed in the 1990s by housing construction near Granite Bay in Sacramento, California, and stored in a museum. Now, Brian Atkinson, assistant professor of ecology & evolutionary biology at the University of Kansas, discovered that the find pushes back the known origins of lamiids to the Cretaceous, extending our knowledge of nearly 40,000 species of flowering plants, including modern-day staple crops like coffee, tomatoes, potatoes, and mint.
