The aftermath of the asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth. [13] The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures which ...

The extinction event produced major changes in Paleogene insect communities. Many groups of ants were present in the Cretaceous, but in the Eocene ants became dominant and diverse, with larger colonies. Butterflies diversified as well, perhaps to take the place of leaf-eating insects wiped out by the extinction.
The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, [ 37 ] with the small but well-funded European continent having a large percentage of ...
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium.
Harvard researchers found that when a meteorite nicknamed S2 paid a visit to our planet 3 billion years ago, it may have helped life flourish.
The Hickman crater is a recently discovered meteorite impact crater, 16 kilometres northeast of the Hope Downs 4 Mine and 35 kilometres north of Newman in the Ophthalmia Range, Western Australia. It was discovered by Arthur Hickman , a government geologist with the Geological Survey of Western Australia , in July 2007. [ 1 ]
