If an industrial civilization had existed on Earth many millions of years prior to our own era,
what traces would it have left and would they be detectable today? We summarize the likely …

Mass extinction events affect a wide breadth of ecosystems and are one of the major driving
mechanisms behind evolution, origination, and diversification of taxa. Such dramatic …

The ability to resolve the stratigraphic record of Earth history is critical to understanding past
global change events and the range of natural variability within the global paleoclimate. The …

The stratigraphic record preserves a library of global climate change that allows us to use
the past as the key to the present by studying prior examples of the multiple climate states of …

Sea level is not static, but liable to fluctuations due to addition or subtraction of water in the
world's oceans, as well as changes to the shape and holding capacity of ocean basins …

Understanding ancient climate changes is hampered by the inability to disentangle trends in
ocean temperature from trends in continental ice volume. We used carbonate “clumped” …
