The extinction of the dinosaurs remains one of the world's enduring mysteries, but a project getting underway off the coast of Mexico may provide some answers.
A team of researchers from the US and the UK will be drilling into the Chicxulub Crater, which was created when an asteroid hit the earth more than 60 million years ago.
