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]
Anomalocaris ("unlike other shrimp", or "abnormal shrimp") is an extinct genus of radiodont, an order of early-diverging stem-group marine arthropods.. It is best known from the type species A. canadensis, found in the Stephen Formation (particularly the Burgess Shale) of British Columbia, Canada.
Bosworthia is a genus of branching photosynthetic alga known from the Middle Cambrian Burgess Shale. 20 specimens of Bosworthia are known from the Greater Phyllopod bed, where they comprise 0.04% of the community. [1] One of its two original species has since been reassigned to Walcottophycus. [2]
Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
This genus has been interpreted as a cyanobacterium, but also resembles the modern cladophoran green algae. It is known from the Middle Cambrian Burgess shale and Early Cambrian deposits from the Czech Republic. It consists of a dense mass of entangled, twisted filaments.
Morania is a genus of cyanobacterium preserved as carbonaceous films [1] in the Middle Cambrian Burgess Shale. [2] it is present throughout the shale; [3] 2580 specimens of Morania are known from the Greater Phyllopod bed, where they comprise 4.90% of the community. [2] It is filamentous, [1] forms sheets, [3] and resembles the modern ...
