Hints: Hints: London the Gulf of Mexico Hiroshima bombs the Atlantic
As they died they slowly sank, settling in layers on the seafloor. Through time they formed these cliffs in an ocean that was up to 300 meters deeper than we see it today. Just imagine how London might have looked back then. All this flooding was triggered by rising seafloors and a warming climate, causing the ice caps to melt, a cataclysm that resulted in much of the continent's disappearing.
But it wasn't these rising seas that spelt the end for the dinosaurs, it was an event that happened 30 million years later and half a world away.
A giant meteorite crashed into the Gulf of Mexico. The destructive power equaled 5 billion Hiroshima bombs. Shock waves swept across the Atlantic.
