Most of you know that I'm a big fat nerd when it comes to deep-marine turbidity currents* and the sedimentary deposits they create - turbidites (e.g., here, here, here, and here). In fact, my current ...
The Neoproterozoic interval of "hidden" evolution refers to a gap of unknown duration between the time when animals first evolved (uncertain) and the oldest known fossil or geochemical evidence of ...
Unsurprisingly, the record of microfossils in Neoproterozoic glacial deposits is relatively scarce, but the rare deposits that do preserve organic-walled microfossils in shales record assemblages ...
The Neoproterozoic Noonday Dolomite (Death Valley, USA), a post-glacial cap carbonate, contains closely packed, meter-long, cm-wide, tube-like structures that define the vertical accretion direction.
The Cambrian "explosion" of multicellular animal life is one of the most significant evolutionary events in Earth's history. But what was it that jolted the Earth system enough to prompt the evolution ...
Scientists have been mystified as to why animals are missing in much of the fossil record. Researchers have now developed a new method to determine if animals really were absent during certain ...
For insight into what can happen when the Earth's carbon cycle is altered -- a cause and consequence of climate change -- scientists can look to an event that occurred some 720 million years ago. New ...
