Marpolia has been interpreted as a cyanobacterium, but also resembles the modern cladophoran green algae. It is known from the Middle Cambrian Burgess shale [1] and Early Cambrian deposits from the Czech Republic. [2] It comprises a dense mass of entangled, twisted filaments.
Fuxianospira gyrata is a Cambrian macroalgae found in the Chengjiang lagerstätte. [1] Preserved in clustered, helicoid groups, the filaments are threadlike, plain and without branches. [ 1 ] Brown and smooth in appearance, these structural characteristics display a resemblance to modern brown algae. [ 2 ]

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]
The extinct Solenoporaceae have traditionally been interpreted as a group of red algae ancestral to the Corallinales. [4] The genus from which they take their name, Solenopora, originates in the Ordovician. [5] Unlike the Corallinaceae, this family has large vegetative cells and an undifferentiated thallus. [5]
A Cambrian stem-group chaetognath, Timorebestia, first described in 2024, was much larger than modern species, showing that chaetognaths occupied different roles in marine ecosystems compared to today. [43] A more recent chaetognath, Paucijaculum samamithion Schram, has been described from the Mazon Creek biota from the Pennsylvanian of Illinois.
