The oldest plants in the world have been found in fossils in India. The ancient rocks resemble red algae, which lived 1.6 billion years ago. Scientists from the Swedish Museum of Natural History discovered the fossils in an ancient rock outcrop in central India. Therese Sallstedt, Department of Paleobiology, found cyanobacteria in the fossils. Cyanobacteria are single-cell life forms that are among the oldest known fossils in the world. Therese Sallstedt
