How worms shaped Earth's biodiversity explosion

One of Earth's most consequential bursts of biodiversity—a 30-million-year period of explosive evolutionary changes spawning innumerable new species—may have the most modest of creatures to thank for the vital stage in ...

Separating out signals recorded at the seafloor

Blame it on plate tectonics. The deep ocean is never preserved, but instead is lost to time as the seafloor is subducted. Geologists are mostly left with shallower rocks from closer to the shoreline to inform their studies ...

Research finds 'fool's gold' not so foolish after all

New marine sulfur cycle model after the Snowball Earth glaciation

The Sturtian Snowball Earth glaciation (~717-660 million years ago) represents the most severe icehouse climate in Earth's history. Geological evidence indicates that, during this glaciation, ice sheets extended to low latitudes, ...

Asteroid impact enriches certain elements in seawater

Asteroid strikes upset the environment and provide clues via the elements they leave behind. Now, University of Tsukuba researchers have linked elements that are enriched in the Cretaceous–Paleogene (KPg) boundary clays ...
