New discovery and it might alter the views on their habits and as well as their extinction.
Story:
Many dinosaurs may have been warm-blooded just like mammals or birds, potentially explaining their extraordinary success before their extinction.
For decades, scientists assumed that because dinosaurs resembled lizards, they were cold-blooded as well, their internal temperature rising and falling with the outside world. However, birds are warm-blooded, and the fact that birds seem to be descended from dinosaurs raises the question of whether their ancestors were as well.
If dinosaurs were warm-blooded, they would have possessed the potential for athletic abilities rivaling those of mammals and birds. They could have survived in colder habitats that would kill cold-blooded creatures, such as high mountain ranges and polar regions, enabling them to cover the entire landscape. Such advantages do carry a price — warm-blooded animals need much more food than their cold-blooded counterparts because their rapid metabolisms fatally malfunction if they cool down too much from lack of fuel.
