This fossil was a puzzle, as its head looked rather like that of an arthropod but its body, with what seemed to be fins along its back and belly, looked rather like of a chordate's.[1] In 2010 Smith and Caron described another 91 specimens, some very good, and reconstructed it as a cephalopod, and the earliest one as of 2010. Unlike later cephalopods it had only two arms, and its eyes seem mounted on stalks. But it had a soft funnel, similar to the ones used for propulsion by modern cephalopods.
