The role of experiments in investigating the taphonomy of exceptional preservation (2016, background): “E, phosphatized Parapandorina raphospissa from the Doushantuo Formation, China; D, two-cell stage; E, nanocrystallites of apatite in a substrate microfabric typical of the preservation of such structures (adapted from Xiao and Knoll 2000).”
Eukaryotic organisms in Proterozoic oceans (2006, background): “Complicating the issue further, there is no reason to believe that oxygen levels trendedmonotonically through the Proterozoic Eon.”
The Multiple Origins of Complex Multicellularity (2011, background): “Ediacaran rocks of broadly comparable age in China contain beautifully preserved microfossils interpreted as metazoan eggs and embryos (Figure 4; Xiao & Knoll 2000).”
The Weng'an biota and the Ediacaran radiation of multicellular eukaryotes (2014, background): “17 Megasphaera was compared with embryos of crown-group animals [16, 136].”
AUTECOLOGY AND THE FILLING OF ECOSPACE: KEY METAZOAN RADIATIONS (2007, background): “…modularity of the rangeomorphs (Narbonne 2004; Xiao et al. 2005) and the remarkable preservation of fossil embryos in the Duoshantuo Formation (Xiao and Knoll 2000); and, finally (4) comparative developmental biology (‘evo-devo’), which has revealed a rich source of information about highly…”
Biomineralization and Evolutionary History (2003, unknown): “Biomarkers ascribed to alveolates have been found in shales as old as 1100 million years (Summons and Walter 1990), but animals are unknown before 600 million years ago (Xiao and Knoll 2000).”
THE EDIACARA BIOTA: Neoproterozoic Origin of Animals and Their Ecosystems (2005, background): “The discovery of fossilized cnidarian and possibly bilaterian eggs and embryos (Xiao et al. 1998, Xiao & Knoll 2000) in phosphorites of the Doushantuo Formation of China represents a significant development in Ediacaran paleobiology.”
Biological Physics of the Developing Embryo (2005, unknown): “It is significant, therefore, that such structures have been found in Ediacaran-period sediments dating from ∼ 600 Ma unaccompanied by the ‘‘adult” metazoan forms characteristic of the later Cambrian period (Xiao and Knoll, 2000; Xiao et al., 2000; Chen, J. -Y., et al., 2004).”
Borings in Cloudina Shells: Complex Predator-Prey Dynamics in the Terminal Neoproterozoic (2003, background): “…is underlain by interbedded phosphatic calcareous shale, dolomite, sandstone, and siltstone laterally equivalent to the Doushantuo Formation, which elsewhere yields the remarkable phosphatized biota of embryos, non-mineralized tubes, and acritarch cysts (Xiao and Knoll, 2000; Xiao et al., 2000).”
Proterozoic phytoplankton and timing of Chlorophyte algae origins (2011, background): “Previously in acritarchs, only Tianshushania represents evidently animal resting eggs and embryos (Xiao and Knoll 2000; Yin et al. 2004).”
