organism Margaretia dorus resembles an Alcyonarian, according to C.D. Walcott (1931), and was reclassified as green algae closely resembling modern Caulerpa by D.F. Satterthwait in her Ph.D. thesis in 1976 and confirmed by Conway Morris and Robison in 1988. Otherwise their fossil record can be traced back to the Cretaceous.
