Velumbrella
''Velumbrella'' is a medusoid organism with tentacles〔 〕 known from the Middle Cambrian of Poland, and perhaps related to ''Rotadiscus''; the fossils depict a scleritosed disk with a U-shaped gut. It was originally related to members of the Ediacara biota〔 〕 but is now thought to be related to the paropsonemids.〔 〕 ==References==
