Space impact killed the dinosaurs

An international panel of experts have come to the conclusion that a space impact was responsible for the extinction of the dinosaurs.

They reached the consensus after conducting the most wide-ranging analysis yet of the evidence.
Writing in Science journal, they rule out alternative theories such as large-scale volcanism

The analysis has been discussed at the 41st Lunar and Planetary Science Conference (LPSC) in the US.A panel of 41 international experts reviewed 20 years’ worth of research to determine the cause of the Cretaceous-Tertiary (K-T) mass extinction, around 65 million years ago.

The extinction wiped out more than half of all species on the planet, including the dinosaurs, bird-like pterosaurs and large marine reptiles, clearing the way for mammals to become the dominant species on Earth.

Their review of the evidence shows that the extinction was caused by a massive asteroid or comet smashing into Earth at Chicxulub on Mexico’s Yucatan Peninsula.
