A group at Cardiff University in Britain has discovered archaeologists in sediments of 111 million years after traveling 1.6 kilometers at the bottom of the Atlantic Ocean. The research focused on knowing how deep living beings reach, that is, how deep the biosphere reaches in the seabed. In fact, several experts have suggested that two-thirds of the Earth's prokaryotes live under the sea floor and should reach up to four or five kilometers. Suggest yes, but so far no one found living things more than 842 meters from the seabed.
