It is produced by a variety of organisms in shallow marine environments globally and appear as lineated features in sedimentary rocks. The phrase, “worm borrows” comes to mind at the sight of the winding shapes. The finding is significant, Pratt explained, as it's long been believed that animals couldn't survive in the seabed because of a lack of oxygen.
