Taxonomic remark From Wang et al., 2016: Grypania [hence: Grypaniaceae] has been commonly regarded as a eukaryotic macroalga (e.g., Walter et al. 1976, 1990, Hofmann 1985, 1992, Runnegar 1991, Han & Runnegar 1992, Samuelsson & Butterfield 2001, Niu 1998, Sun et al. 2006, Knoll et al. 2006, Butterfield 2009, Sharma & Shukla 2009c, Xiao 2013, Wang et al. 2014) but alternative interpretations have been proposed: (1) pseudofossil (Horodyski 1986), (2) prokaryote (Vidal 1989, Niu 1998, 2002), (3) cyanobacteria (Kumar 1995), (4) trace fossil (Walcott 1899, Mathur 1983, Du & Tian 1985, Yan & Liu 1998), (5) probable metazoan (Tandon & Kumar 1977, Chen 1989, Chen et al. 2000) and (6) uncertain affiliation (Du et al. 1986, Chen 1999, Sharma & Shukla 2009a, Shi et al. 2014). Most commonly, the large ribbon-like form of Grypania has been regarded to reflect a photosynthetic organism (Walter et al. 1990, Sharma & Shukla 2009c, Payne et al. 2011). [details]
