Evidence of ancient life discovered in mantle rocks deep below the seafloor — ScienceDaily

Ancient rocks harbored microbial life deep below the seafloor, reports scientists. This first-time evidence was contained in drilled rock samples of Earth’s mantle — thrust by tectonic forces to the seafloor during the Early Cretaceous period. The discovery confirms a long-standing hypothesis that interactions between mantle rocks and seawater can create potential for life even in hard rocks deep below the ocean floor.
