Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million…
Artist’s rendering of a comet headed towards Earth. New theory explains possible origin of the Armageddon-causing object. It forever changed history when it crashed into…
New research suggests that overhunting by humans was not responsible for the extinction of mammoths, ground sloths, and other North American megafauna. A new study…
A new study applies machine learning to the fossil record to visualize life’s history, showing the impacts of major evolutionary events. This shows the long-term…
Mass extinctions align with major asteroid impacts and devastating volcanic outpourings of lava called flood-basalt eruptions. Researchers find that timing of mass extinctions lines up…
Titanosaurs were common at the time of the asteroid hit at the end of the Cretaceous 66 million years ago. A new statistical analysis of…
The researchers found coronene-mercury enrichments in sedimentary rocks deposited in southern China and Italy 252 million years ago. Paired coronene — mercury enrichments are products…
