“Dinosaurs killed off by ‘one-two punch’ of climate change and asteroid strike – study”

Scientists have long debated the cause of the so-called Cretaceous-Palaeogene mass extinction, which led to the rise of the mammals.


The dinosaurs’ long reign was not ended swiftly but by torturous millennia of climate change before and after a giant asteroid slammed into Earth, scientists have said.

The dinosaurs’ demise, according to US-based researchers in the new paper, was caused by two periods of global warming – the first sparked by monster volcanic eruptions in what is India today, and the second by the asteroid’s impact.
