Dinosaurs died from sudden temperature drop 'not comet strike', scientists claim
British researchers claim that a sudden plummeting in the sea temperature of 16F (9C) more than 137 million years ago was the first step towards their eventual road to extinction.
While studying fossils and minerals from the Arctic Svalbard, Norway, they concluded the sudden change in the Atlantic Gulf Stream during the Cretaceous period would almost certainly have wiped out the ''abundance'' of the world's dinosaurs.
Some experts believe the creatures were wiped out by one cataclysmic event 65 million years ago – such as a meteor hitting the planet.
But the new research suggests they were wiped out by a series of environmental changes, starting with a drop in sea temperatures.
