A team of marine biologists, Earth scientists and evolutionary specialists affiliated with several institutions in the U.K., has found that prior researchers studying a fossil of an ancient sea creature called Pikaia were looking at it upside down. In their study, published in the journal Current Biology, the group found that a blood vessel running along what was reported to be its belly was actually a dorsal nerve cord.
