veral meters of water, but also in intertidal deposits right at the shoreline. The use of this burrow (most likely produced by soft-bodied worms known as priapulids) to delineate the Ediacaran-Cambrian boundary has been controversial because many scientists believed its presence was restricted to certain environments, therefore reducing its utility as a general fossil guide. To establish the broad environmental tolerance of this form, the research team combined detailed field work with conceptual and methodological tools employed in the recently established field of Stratigraphic Paleobiology. This study provides a solid base to the paleontologic criteria employed to establish the Ediacaran-Cambrian boundary, a topic that is receiving huge attention within the paleobiological and geological community because of its implications for the early evolution of life.


Using repeating volcano-tectonic earthquakes to track post-eruptive activity in the conduit system at Redoubt Volcano, Alaska Helena Buurman et al., Alaska Volcano Observatory, Geophysical Institute, University of Alaska Fairbanks, 903 Koyukuk Drive, Fairbanks, Alaska 99775-7320, USA. Posted online 7 Feb. 2013; http://dx.doi.org/10.1130/G34089.1.

Redoubt Volcano erupted for 3 months in 2009, generating spectacular ash clouds and producing a large lava dome that remains in place today. Both this eruption and the last eruption in 1989 were preceded by bursts of earthquake activity -- known as earthquake swarms-- that provided scientists with early warning of the imminent eruption. When more earthquake swarms occurred around the vent in the year after the eruption, the alert levels were raised in anticipation of eruptive activity. No eruption occurred, however, so the earthquakes were dismissed as having occurred either within the cooling lava dome or in the summit glaciers rather than being generated by the volcano. H
