“…Black shales in the Ediacaran Doushantuo Formation or equivalent lithostratigraphic units are also exposed at Taoying, Jiangkou County, Guizhou Province [14] , and at Lantian, Xiuning County, Anhui Province [7,15,16] . They too contain well-preserved macroscopic remains.…”

“…They too contain well-preserved macroscopic remains. The macroscopic assemblages, from the above-mentioned localities are dominated by many kinds of benthic multicellular algae with branching and holdfast structures, and were deposited in a partly enclosed shallow-water environment similar to the Miaohe assemblage [14][15][16][17] . The Lantian benthic assemblage also contains fan-like forms with numerous filaments as well as pyritized chuarids with medial split excystment structures [16,18] , which are also considered as the "genital butt" structures of advanced algae [19] .…”

“…This macrobiota, compression fossils including megascopic algae, possible metazoan and trace fossils, might correlate with the Miaohe biota from Western Hubei and the Lantian flora from Southern Anhui (Zhao et al, 2004;Wang et al, 2005). The Chinese Doushantuoan biota were mainly composed of macroalgae (Bi et al, 1987;Chen and Xiao, 1991;Chen et al, 1994a;1994b;Ding et al, 1996;Tang et al, 1997;Yuan et al, 1999;Xiao et al, 2002;Yuan et al, 2002;Zhao et al, 2004;Wang et al, 2005). Most of these macroalgae, which were fixed on the sea floor by their holdfast (Chen et al, 1994b;Ding et al, 1996;Chen et al, 2000;Hu, 1997;Xiao et al, 2002;Yuan et al, 2002;Wang et al, 2005), formed a primitive "submarine grassland" (Chen et al, 1994b;2000;Wang et al, 2005).…”

Numerous macro-organisms of the Doushantuo macrobiota, which were found in the black carbonaceous mudstone of the upper Neoproterozoic Ediacraan Doushantuo Formation in Jiangkou County, Guizhou Province, China, are considered to live on sea floor by their holdfasts. The appearance and preserved forms of the macroalgal holdfasts may provide some data to the study of the living and buried environments of macrobiota. They lived in the lower energy and clear environment, and fixed on a soupground with rich water (about 79% water). Currents, possibly ocean currents, could pull out the macroalgal holdfasts from the soupground and break off the macroalgal foliations. After such events, the corpses of macro-organisms would be covered in a reduced environment by the deposits. Afterwards, a new community, including regenerating and undying macro-organisms, lived continuously on a new deposit.

“…Comparison: The complexity of the sub-branching represents a greater degree of evolution than is present in Proterozoic algae, which are found in strata of 1.7-0.54 Ma [25][26][27][28][29][30][31][32][33][34]. From the general shape, the alga is similar to Hallucigenia.…”

The Kaili Biota of Jianhe County, Guizhou Province is found in a Burgess Shale type of deposits, and as such it provides a key fossil record for studying biotic differentiation following the Cambrian explosion. Macroalgae represent several important groups of primary producers and yet have not been well studied. Here, we report two new forms of macroalgae from the Kaili Biota, including a new genus and species and an indeterminate genus and species. The new genus and species, Parallelphyton tipica, is a heterotrichous alga with thalli composed of a prostrate cardinal axis, and parallel bundles of erect trichomes on the axis. The bifurcation of the trichomes is somewhat similar to the living heterotrichous Fritschiella (Chlorophyta), representing "architectonic differentiation" only known in higher plants as an adaptation to terrestrial conditions. The indeterminate genus and species consists of an arched, thick, cylindrical major shaft and irregularly spaced, curved lateral branches attached to the major shaft and subdivided into subbranches. The characteristics of the thick and strong major shaft and the lateral branch subdivided branches are analogous to the dichotomous branching of Psilophyton in Protopteridophyta. Thus, the differentiation of the thalli in these two algal forms represents the expression of properties of some higher metaphytes, indicating that the ecological differentiation of the macroalgae was well underway at the time of the Kaili Biota.
