Reevaluating Links Between Meteorite Impacts and Early Cenozoic Global Warming
The Paleocene‐Eocene Thermal Maximum (PETM) and the lower Chron 29n hyperthermal event were recently proposed to have been triggered by the meteorite impacts that formed the Marquez Dome (Texas, USA;

Dynamical Origin and Terrestrial Impact Flux of Large Near-Earth Asteroids
Dynamical models of the asteroid delivery from the main belt suggest that the current impact flux of diameter km asteroids on the Earth is ≃0.5–1 Gyr−1. Studies of the Near-Earth Asteroid (NEA)
An asteroid breakup 160 Myr ago as the probable source of the K/T impactor
TLDR
It is argued that this apparent surge in impact flux was triggered by the catastrophic disruption of the parent body of the asteroid Baptistina, which it is inferred was a ∼170-km-diameter body (carbonaceous-chondrite-like) that broke up Myr ago in the inner main asteroid belt.
Discovery of a 25-cm asteroid clast in the giant Morokweng impact crater, South Africa
TLDR
The discovery of a large (25-cm), unaltered, fossil meteorite and several smaller fragments within the impact melt of the giant Morokweng crater, South Africa, suggests that the MorokWeng asteroid incorporated part of the LL chondrite parent body not represented by objects at present reaching the Earth.
Forming the Flora Family: Implications for the Near-Earth Asteroid Population and Large Terrestrial Planet Impactors
Formed from a catastrophic collision of a parent body larger than 150 km in diameter, the Flora family is located in the innermost part of the main belt near the secular resonance. Objects in this
A meteorite from the Cretaceous/Tertiary boundary
Cretaceous/Tertiary boundary sediments are now widely recognized to contain the record of a large asteroid or comet impact event, probably at the site of the Chicxulub crater on the Yucatan
Modeling the Historical Flux of Planetary Impactors
The impact cratering record of the Moon and the terrestrial planets provides important clues about the formation and evolution of the solar system. Especially intriguing is the epoch ≃3.8–3.9 Gyr ago
Impact spherules as a record of an ancient heavy bombardment of Earth
TLDR
Estimates of the sizes and impact velocities of the asteroids that created global spherule layers reveal that the impactor flux was significantly higher 3.5 billion years ago than it is now, consistent with a gradual decline of theimpactor flux after the Late Heavy Bombardment.
