Recent advances in understanding the terminal Ediacaran Earth-life system in South China and Arctic Siberia

espanolEl Ediacarico terminal inlcuye una serie de cambios drasticos en los ciclos biogeoquimicos, muchos de los cuales se asocian con modificaciones evolutivas en los registros fosiles correspondientes. Entre ellos destacan las condiciones redox, las cuales pueden haber causado un impacto profundo en la evolucion animal temprana. Este trabajo destaca el significado de la lito-, bio- y quimioestratigrafia en la investigacion geobiologica del tiempo profundo. EnglishThe terminal Ediacaran contains dramatic changes in biogeochemical cycles, many of which are closely coupled with evolutionary transitions in the corresponding fossil records. Dynamic redox conditions may have caused a profound impact on early animal evolution. Our work highlights the significance of integrated bio-, litho-, and chemo-stratigraphy in geobiology research of the deep time.
