Magnetofossils Unveil Paleoredox Conditions in Extreme Climate
The Paleocene-Eocene Thermal Maximum, a thermal pulse about 56 million years ago, is an analog for future global warming. A new magnetofossil study shows progressive ocean deoxygenation.
A Spike in Wildfires Contributed to the End-Permian Extinction
An upward trend in fossilized charcoal indicates that wildfires may have contributed to extinctions during the Great Dying.
Cretaceous Charcoal Gives a Glimpse of Plant Evolution
New data from vegetal charcoal in northwest India supports the theory of paleowildfires as a global phenomenon and an evolutionary force for biodiversity.
When Climate Ruled the Dinosaurs of Grand Staircase
Living in Geologic Time: Navigate the prolific boneyards and shifting boundaries of Grand Staircase-Escalante and Bears Ears National Monuments.
Mammoths Lost Their Steppe Habitat to Climate Change
Ancient plant and animal DNA buried in Arctic sediments preserve a 50,000-year history of Arctic ecosystems, suggesting that climate change contributed to mammoth extinction.
Greener, Wetter Arabia Was a Crossroads of Early Human Migration
Hand axes, hippo bones, and a stack of ancient lake beds show that arid Arabia experienced intervals of humid weather, spurring pulses of human migration over the past 400,000 years.
Multicellular Algae Discovered in an Early Cambrian Formation
A new study describes eukaryotic organisms found organized in a cortex-medulla pattern in southern China’s Kuanchuanpu Formation.
The Rocky Roads of Colombian Paleontology
Colombia has a wealth of fossils, and geologists are leading the charge to both collect data and share ancient history with local communities.
Sooty Layers in Stalagmites Record Human Activity in Caves
Scientists analyzing cave formations in Turkey find layers of soot and charcoal in stalagmites, revealing that humans—and their fires—occupied caves thousands of years ago.
