Key Facts About The Bird Has No Teeth

According to research by experts at the University of Toronto (Canada), the ancestors of modern birds have a hard beak structure and a nut-seed diet. And this is the reason why they survived the extinction disaster at the end of the Cretaceous period.

More than 60 million years ago, meteorite disasters hit the Earth, causing climate change, food sources become extremely scarce. leading to the extinction of animals like carnivorous dinosaurs, lizards, including species belonging to the family Maniraptoran (dinosaur family including birds).

Why The Bird Has No Teeth Matters

But birds with beaks but no teeth survived strangely through that great extinction.

From data analyzing more than 3,000 fossil teeth samples of 4 groups of the Maniraptoran family, experts believe that the diet is the main factor that helps the ancestors of modern birds survive at that time.

Research, experts found that in the White Pollen, modern bird relatives ate nuts. And modern birds all have mines but no teeth. This means that 60 million years ago, the birds had become extinct, only the birds of the tooth thanks to the menu that survived the grain to this day.

Is this answer surprisingly interesting? This study is published in Current Biology.
