Margaretia is a frondose organism known from the middle Cambrian Burgess shale and the Kinzers Formation of Pennsylvania. [1] Its fronds reached about 10 cm in length and are peppered with a range of length-parallel oval holes. It was originally interpreted as an alcyonarian coral. [2] It was later reclassified as a green alga closely resembling modern Caulerpa by D.F. Satterthwait in her Ph.D. thesis in 1976, [3] a finding supported by Conway Morris and Robison in 1988. [2] More recently, it has been treated as an organic tube, that is used as nest of hemichordate Oesia. [4]
