Did asteroid kill the dinosaurs? This study reveals shocking details - HT Tech

The reason behind the extinction of dinosaurs has always been blamed on a massive asteroid strike around 66 million years ago?

According to the old theory behind the extinction of dinosaurs, all the non-avian dinosaurs were killed either by the explosion itself or the acid rain and darkness, which lasted for decades.

The disappearance of the non-avian dinosaurs on Earth gave space for the emergence of mammals as the dominant animal group on Earth, the report suggested.

Hence, the low number of dinosaur species for the last few million years is expected to result from global climate fluctuations and massive volcanic eruptions.
