Charniodiscus was first found in Charnwood Forest in England, and named by Trevor D. Ford in 1958. The name is derived from the fact that Ford only described a holdfast consisting of a double concentic circle, his species being named Charniodiscus concentricus. Later it was discovered that a frond (Charnia masoni) was part of a closely related organism. Charnia differs in the branching structure in the frond. Charniodiscus specimens are known from across the globe dating to around 565 to 555 million years ago.

- 查恩盤蟲（學名：Charniodiscus ）是一種Ediacaran時期的化石，估計其在世時應該是一種固定的底棲性動物，生活於沙質的海床。 The organism had a holdfast, stalk and frond. The holdfast was bulbous shaped, and the stalk was flexible. The frond was segmented and had a pointed tip. There were two growth forms: one with a short stem and fat frond, and another with a long stalk, elevating a smaller frond about above the holdfast. While the organism superficially resembles the sea pens (cnidaria), it is probably not a crown-group animal. Charniodiscus specimens are known from across the globe dating to around .
