“…Of particular note is the Strelley Pool Formation, which not only contains the largest spheres and filaments, but also spindle-like structures that can have diameters well in excess of 50 µm (Sugitani et al 2010;Wacey et al 2011). Fewer fossils have been documented from the Swaziland Supergroup of the Barberton Greenstone Belt, although spheres, filaments and spindles are all represented, along with putative rods and sausage-shaped cells (Knoll & Barghoorn 1977;Walsh & Lowe 1985;Walsh 1992;Westall et al 2001a;Tice & Lowe 2004;Westall et al 2006b). Of particular note in the South African deposits are very large spheres (30-300 µm) discovered within siliciclastic sediments of the 3.2 Ga Moodies Group (Javaux et al 2010).…”

“…The earliest fossiliferous deposits are found in the East Pilbara Granite-greenstone Terrane of the Pilbara Craton, Western Australia (Van Kranendonk 2006;Wacey 2012) and the Barberton Greenstone Belt, South Africa (Walsh 1992;Westall et al 2006b). Both sites contain rocks of Palaeoarchean age with metamorphosed approaching 3.5 Ga containing the first indications for life (body fossils).…”

“…La presencia de microfósiles, microbialitas, y biomarcadores moleculares e isotópicos en rocas de más de 3000 Ma, indican que la vida microbiana era abundante en ambientes marinos, someros y profundos del Arqueano (Lowe, 1980;Walter et al, 1980;Awramik et al, 1983;Schopf, 1983;Walter, 1983;Walsh y Lowe, 1985;Rasmussen, 2000;Westall et al, 2001;Furnes et al, 2004;Shen y Buick, 2004;Tice y Lowe, 2004;Allwood et al, 2006;Banerjee et al, 2006;Westall et al, 2006aWestall et al, , 2006bUeno et al, 2006;Schopf et al, 2007 y referencias incluidas;Shen et al, 2009;Westall, 2010;Wacey et al, 2011). Ello apoya la idea de que las zonas costeras estuarinas fueron muy productivas en aquel tiempo, y que la fotosíntesis ya estaba operando (Awramik, 1992;Rosing y Frei, 2004;Tice y Lowe, 2004;Buick, 2008;Hoashi et al, 2009;Kato et al, 2009;Kendall et al, 2010), aunque tal vez no necesariamente oxigénica (Westall et al, 2011;Li et al, 2012).…”

“…An important aspect of the discussion about the onset of life development on Earth has been the role that water, one of the essential ingredients for the formation of life on this planet (for discussion of origin of life on Earth and Archean evidence for early life, see e.g., Westall et al 2006;Schopf 2006, and references therein), must have played, from the start. Was water readily available on the Hadean/Archean planet Earth?…”
