A New Period for the Geologic Time Scale
@article{Knoll2004ANP, title={A New Period for the Geologic Time Scale}, author={Andrew H. Knoll and Malcolm R. Walter and Guy M. Narbonne and Nicholas Christie‐Blick}, journal={Science}, year={2004}, volume={305}, pages={621 - 622} }
The geologic time scale is in need of an update, given that the last modification took place in 1891. In their Perspective, [Knoll and colleagues][1] announce the proud addition of a new interval to the geologic time scale, the Ediacaran Period, by the International Union of Geological Sciences.

A uranium-lead zircon age for a volcanic ash interstratified with fossil-bearing, shallow marine siliciclastic rocks in the Zimnie Gory section of the White Sea region indicates that a diverse assemblage of body and trace fossils occurred before 555.3 +/- 0.3 million years ago, making co-occurring trace fossils the oldest that are reliably dated.
Stable isotopic evidence for methane seeps in Neoproterozoic postglacial cap carbonates

Carbon isotopic and petrographic data from a Neoproterozoic postglacial cap carbonate in south China are reported that provide direct evidence for methane-influenced processes during deglaciation, lending strong support to the hypothesis that methane hydrate destabilization contributed to the enigmatic cap carbonates deposition and strongly negative carbon isotopic anomalies following Neopropriaterozoic ice ages.
