Impact or eruptions: Are both to blame in the great end-Cretaceous whodunit?

Few episodes in geologic history are as widely recognized — and debated — as the end-Cretaceous extinction. For several decades, the Chicxulub impact has been the primary suspect. But new research suggests the impact wasn’t solely responsible for the extinctions; widespread volcanism in India seemed to play a role as well.

What lies below?

Technological advances continue to improve the resolution of our view of Earth’s interior, but disagreement remains over what we’re viewing. In a recent Nature paper titled, “Broad plumes rooted at the base of the Earth’s mantle beneath major hot spots,” Scott French, a computational scientist at the Department of Energy’s National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory, and Barbara Romanowicz, a seismologist at the University of California at Berkeley, reported the development of the most detailed model yet of the structure of the mantle.

The Snowmastodon Project: Mammoths and mastodons lived the high life in Colorado

In fall 2011, a bulldozer driver in Snowmass, Colo., unearthed an unprecedented trove of Pleistocene-aged fossils. Over the next few months, “Snowmastodon” became one of the largest fossil excavations ever. Scientists have already learned a lot from the bones.
