Rotadiscus is a genus of discoidal animal known from the Cambrian Chengjiang biota[2] and classified with the eldoniids.[3]
As with other eldoniids, it was originally thought to have been pelagic, but is now thought to be benthic.
A 2023 cladistic analysis based on new fossils places Rotadiscus, along with other eldoniids, as stem-group ambulacrarians.[4]
