The Stratigraphic Relationship Between the Shuram Carbon Isotope Excursion, the Oxygenation of Neoproterozoic Oceans, and the First Appearance of the Ediacara Biota and Bilaterian Trace Fossils in Northwestern Canada
(Elsevier BV, 2013)
A mechanistic understanding of relationships between global glaciation, a putative second rise in atmospheric oxygen, the Shuram carbon isotope excursion, and the appearance of Ediacaran-type fossil impressions and ...
Searching for an oxygenation event in the fossiliferous Ediacaran of northwestern Canada
(Elsevier BV, 2013)
Late Neoproterozoic (Ediacaran) strata from northwestern Canada provide a thick and rich sedimentological record, preserving intercalated carbonates and shale extending from the ~ 635 million year old Marinoan glacial ...
Oxygen, Ecology, and the Cambrian Radiation of Animals
(Proceedings of the National Academy of Sciences, 2013)
The Proterozoic-Cambrian transition records the appearance of essentially all animal body plans (phyla), yet to date no single hypothesis adequately explains both the timing of the event and the evident increase in diversity ...
Late Ediacaran Redox Stability and Metazoan Evolution
(Elsevier, 2012)
The Neoproterozoic arrival of animals fundamentally changed Earth's biological and geochemical trajectory. Since the early description of Ediacaran and Cambrian animal fossils, a vigorous debate has emerged about the drivers ...
The Ecological Physiology of Earth's Second Oxygen Revolution
(Annual Reviews, 2015)
Living animals display a variety of morphological, physiological, and biochemical characters that enable them to live in low-oxygen environments. These features and the organisms that have evolved them are distributed in ...
