“…Overall, the decay sequence of Thiomargarita has much in common with those of other bacteria [24]. As in other bacteria, the Thiomargarita sheath is the most resistant structure to decay.…”

“…Although patterns of decay in animal embryos are now being studied [17,[19][20][21][22], nothing is known about decay processes or preservation potential in giant sulphur-oxidizing bacteria. Previous studies on decay of bacteria (see earlier studies [23,24] for reviews) are of limited relevance because of the comparatively small size, lack of central vacuole and lack of successive reductive division in the species studied. In order to address this issue, we experimentally infer a decay sequence for Thiomargarita, and compare the results with the patterns observed in the Doushantuo fossils and other putative fossil eukaryotes.…”

“…Moreover, taphonomic features displayed by Bangiomorpha are similar to those of other early eukaryotes, but different from those of filamentous cyanobacteria known from the Proterozoic fossil record. Bangiomorpha displays three-dimensionally competent preservation of outer and inner walls, with no cytoplasmic preservation, whereas cyanobacterial filaments with sheaths generally show competent three-dimensional preservation of the sheath, but partial or complete collapse of the cells inside (Bartley 1996). Published radiometric dates constrain Bangiomorpha only to the interval 1267G2 to 723G 3 Myr, but an unpublished Pb-Pb date of 1198G 24 Myr and physical stratigraphic relationships strongly suggest that the fossils' age lies close to the lower radiometric boundary (Butterfield 2000).…”

“…The process of fossilisation through calcification has been induced experimentally to study the deterioration of cellular and extracellular (EPS) products under controlled laboratory conditions [31]. Natural fossilisation and early diagenesis have been studied in freshwater carbonate deposits in carbonate regions for example in the USA and Europe [20,32,33] and non-carbonate environments of lacustrine lakes in Antarctica [34].…”
