The dino killing asteroid did not trigger a long lasting winter

The massive asteroid impact that killed the dinosaurs also triggered mega-earthquakes that lasted months.  That was the story until last month.

Now, however, recent research shows that the impact did not trigger a long-lasting  winter.  

According to evolution, roughly 66 million years ago, an asteroid approximately 10 kilometres or 6.2 miles across smashed into Earth near the Yucatan Peninsula, plunging the planet into darkness and causing a mass extinction that wiped out 80% of animal life — including all the non-avian dinosaurs except some who did not, for instance theTuatara  (Sphendon punctatus) that still lives in New Zealand.

However, scientists have discovered an ancient lakebed buried under more than 1,5 kilometres or a mile of ice that may hold secrets to Greenland's past climate or its ice-free past – that is, the global flood of Noah's flood or 4 500 years ago. and the petrified forests of Antartica also speak of Noah's Flood.
