Velumbrella Explained

Velumbrella is a medusoid organism with tentacles^[1] known from the Middle Cambrian of Poland, and perhaps related to Rotadiscus; the fossils depict a scleritosed disk with a U-shaped gut.^[2] It was originally related to members of the Ediacara biota^[3] but is now thought to be related to the paropsonemids.^[4]
