Looking for dino asteroid material

Scientists say they have a clue that may enable them to find traces of the asteroid that wiped out the dinosaurs in the very crater it made on impact.

This pointer takes the form of a nickel signature in the rocks of the crater that is now buried under ocean sediments in the Gulf of Mexico.

An international team has just drilled into the 200km-wide depression.

Prof Philippe Claeys from the Free University in Brussels told our correspondent Jonathan Amos that nickel was a first step to finding the asteroid's iridium.
