Velumbrella
From Wikipedia, the free encyclopedia
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]
