Double meteorite strike 'caused dinosaur extinction'

The dinosaurs were wiped out 65 million years ago by at least two meteorite impacts, rather than a single strike, a new study suggests.

Previously, scientists had identified a huge impact crater in the Gulf of Mexico as the event that spelled doom for the dinosaurs.

Now evidence for a second impact in the Ukraine has been uncovered.

This raises the possibility that the Earth may have been bombarded by a whole shower of meteorites.

The new findings are published in the journal Geology by a team lead by Professor David Jolley of Aberdeen University.

When first proposed in 1980, the idea that a meteorite impact had killed the dinosaurs proved hugely controversial. Later, the discovery of the Chicxulub Crater in the Gulf of Mexico, US, was hailed as "the smoking gun" that confirmed the theory.

What about the Shiva Crater off Mumbai, India. Much larger than the one at Yucatan or the Ukraine.

Controversy ended.

Two = a swarm

I’m thinking the GofM strike was plenty large enough to do the job.
