A sawtooth-like timeline for the first billion years of lunar bombardment
Abstract We revisit the early evolution of the Moon's bombardment. Our work combines modeling (based on plausible projectile sources and their dynamical decay rates) with constraints from the lunarExpand

The Origin of Planetary Impactors in the Inner Solar System
Insights into the history of the inner solar system can be derived from the impact cratering record of the Moon, Mars, Venus, and Mercury and from the size distributions of asteroid populations. OldExpand

Support for the lunar cataclysm hypothesis from lunar meteorite impact melt ages.
Lunar meteorites represent a more random sampling of lunar material than the Apollo or Luna collections and, as such, lunar meteorite impact melt ages are the most important data in nearly 30 yearsExpand

Cataclysmic bombardment throughout the inner solar system 3.9–4.0 Ga
[1] Cohen et al. [2000] recently confirmed the hypothesis that the Moon was resurfaced by an intense period of impact cratering ∼3.9 Ga ago and, by inference, that the Earth also sustainedExpand

Chicxulub Crater: A possible Cretaceous/Tertiary boundary impact crater on the Yucatán Peninsula, Mexico
We suggest that a buried 180-km-diameter circular structure on the Yucatan Peninsula, Mexico, is an impact crater. Its size and shape are revealed by magnetic and gravity-field anomalies, as well asExpand

The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary
The Fall of the Dinosaurs According to the fossil record, the rule of dinosaurs came to an abrupt end ∼65 million years ago, when all nonavian dinosaurs and flying reptiles disappeared. SeveralExpand

Widespread mixing and burial of Earth’s Hadean crust by asteroid impacts
The history of the Hadean Earth (∼4.0–4.5 billion years ago) is poorly understood because few known rocks are older than ∼3.8 billion years old. The main constraints from this era come from ancientExpand

Isotopic evidence bearing on Late Triassic extinction events, Queen Charlotte Islands, British Columbia, and implications for the duration and cause of the Triassic/Jurassic mass extinction
Stable isotope analyses of Late Triassic to earliest Jurassic strata from Kennecott Point in the Queen Charlotte Islands, British Columbia, Canada shows the presence of two distinct and differentExpand

The Chicxulub impact event and its environmental consequences at the Cretaceous–Tertiary boundary
Abstract An impact-mass extinction hypothesis for the Cretaceous–Tertiary (K/T) boundary transition has been confirmed with multiple lines of evidence, beginning with the discovery of impact-derivedExpand

High-velocity collisions from the lunar cataclysm recorded in asteroidal meteorites
Lunar samples suggest that the inner Solar System was bombarded by asteroids about 4 Gyr ago. Radiometric ages of meteorites suggest an unusual number of high-velocity asteroids at this time,Expand
