In the middle of the Devonian Period some 385 million years ago, the Wissahickon Schist was the heart of a huge mountain chain that was something like the Pacific Northwest of today.Volcanoes formed ...

Paleontologists use ancient marine faunas to test long-term changes in our warming oceans. Members of Syracuse University's College of Arts and Sciences are shining new light on an enduring mystery -- ...

Black shales deposited in epeiric seas preserve dynamic, bottom-water oxygen conditions as inferred from high-resolution trace- and body-fossil data. Nearly all paleoproxies are imperfect; however, ...
