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 ]
Kangina are inexpensive, eco-friendly, and effective vessels for the preservation of fresh fruit. [2] A 2023 study found kangina and polystyrene foam boxes to be the most effective vessels for preserving grapes. [2] The containers are, however, heavy, unwieldy, and prone to absorbing moisture. [2] [6]
The preservational mode is only present in the Precambrian, and is restricted to shallow or tidal waters. [1] After this point, organisms such as sponges extracted silica from the oceans in order to construct tests (skeletons), with the result that the surface oceans no longer became supersaturated with respect to silica when evaporation condensed the mineral.

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.
Estimated to reach 34.2–37.8 cm (13.5–14.9 in) long excluding the frontal appendages and tail fan, [4] Anomalocaris is one of the largest animals of the Cambrian, and thought to be one of the earliest examples of an apex predator, [5] [6] though others have been found in older Cambrian lagerstätten deposits.
It is famous for the exceptional preservation of the soft parts of its fossils. At 508 million years old ( middle Cambrian ), it is one of the earliest fossil beds containing soft-part imprints. During the Cambrian, the ecosystem of the Burgess Shale sat under 100 to 300 metres (330 to 1000 feet) of water at the base of a submarine canyon known ...
Proaulopora is a Cambrian–Ordovician fossil genus of calcareous algae.It has been variously thought to belong to the green algae, red algae or cyanobacteria.It was originally established by the Russian paleontologist Aleksandr Grigoryevich Vologdin [] in 1937, for species known from the Lower Cambrian of the western Altai Mountains.
