Although originally described as an alga, F. gyrata is now regarded by some authors as a coprolite (e.g., Steiner et al. 2005). Taxonomy from GBIF.org. Description and remarks by Chen and Zhou 1997., p. 88 : "Thread cylindrical, unbranchial, with a uniform, flattened width of 1.2mm and a preserved length of at least 20cm. Surface bears a tightly and helically coiled structure. Remarks: This is the most abundant alga in the Chengjiang biota. Most of the thread are preserved within a microturbidite mud layer and show irregular twisting, indicating that the thread was extremely flexible. Specimens probably sank to the bottom from the overlying water column, in a very low-energy environment, before the incursion of minor mud flow.” Restoration by Chen and Zhou 1997., p. 89: References: Chen, J.Y., and Zhou, G., (1997) Biology of the Chengjiang fauna.
