New research led by scientists at the American Museum of Natural History and Yale shows that the oldest ancestors of the group of animals that includes octopuses and vampire squids had not 8 but 10 arms. The study, which describes a new species of vampyropod based on a 328-million-year-old fossil that had not been previously described, pushes back the age of the group by nearly 82 million years. The details are published today in the journal Nature Communications.
