Taxonomic remark From Vorob'eva et al., 2009: Parmia anastassiae was originally described as a population of macroscopic carbonaceous tubes with distinct annulations, interpreted as annelid-like worms (Gnilovskaya, 1998). Subsequent maceration of the same rocks revealed cuticle-like microfossils reasonably interpreted as Parmia tube fragments (Gnilovskaya et al., 2000). ... Biological interpretation of both macroscopic and microscopic Parmia fossils remains a subject for debate. See Dong et al. (2008) for illuminating discussion of broadly similar macrofossils from Tonian to lower Cryogenian shales in China. ... Dong et al. (2008) restudied the Chinese populations, concluding that they probably record epibenthic algae (or possibly, cnidarian-grade animals) rather than motile bilaterians. Such caution applies, as well, to Parmia. [details]
