Palaeontologists characterize mass extinctions as times when the Earth loses more than
three-quarters of its species in a geologically short interval, as has happened only five times …

Non‐avian dinosaurs went extinct 66 million years ago, geologically coincident with the
impact of a large bolide (comet or asteroid) during an interval of massive volcanic eruptions …

The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

The Cretaceous/Paleogene mass extinction, 66 Ma, included the demise of non-avian
dinosaurs. Intense debate has focused on the relative roles of Deccan volcanism and the …

Mass extinctions manifest in Earth's geologic record were turning points in biotic evolution.
We present 40Ar/39Ar data that establish synchrony between the Cretaceous-Paleogene …

Large igneous provinces are exceptional intraplate igneous events throughout Earth's
history. Their significance and potential global impact are related to the total volume of …

We report a time-calibrated stratigraphic section in Colorado that contains unusually
complete fossils of mammals, reptiles, and plants and elucidates the drivers and tempo of …

Mass extinctions are a major pattern in macroevolution. Because of their frequency,
quickness and global effects, they shaped the global biodiversity several times during the …

Abstract The Cretaceous–Paleogene mass extinction approximately 66 million years ago is
conventionally thought to have been a turning point in mammalian evolution,. Prior to that …

Fishes include more than half of all living animals with backbones, but large‐scale
palaeobiological patterns in this assemblage have not received the same attention as those …
