Why do grass-eating dinosaurs have long necks?

The act of swallowing food is considered to be the cause of herbivore dinosaurs with large bodies with long necks and small heads. That is the conclusion of German scientists.

According to a study by Bonn University in Biology, if the dinosaurs stopped to chew they would not have time to eat. Ingestion will help bring food into the stomach quickly. So they need long necks.

Grass-eating dinosaurs have long necks to swallow food.

Animals eat a lot and chew like elephants, need a large head to have enough space for giant jaw and jaw muscles. However, because dinosaurs do not chew food, a big head is not necessary.

In addition, the long neck helps big dinosaurs bring food down faster and do not encounter any stops.

While elephants need 18 hours a day to 'satisfy' hunger, herbivorous dinosaurs need up to 30 hours to fill their empty stomachs. Therefore, swallowing food is necessary for them to shorten the time.

Professor Sander asserts that swallowing food is not harmful to herbivorous dinosaurs.

Professor Martin Sander, Bonn University, said that the act of swallowing trees without chewing is not a big problem for dinosaurs.

The animals belonging to the lizard family often change, about once a month. Large stomachs and intense metabolism help them digest any un-chewed food.

Dinosaurs also possess an effective respiratory system like birds with many air sacs attached to bones and body cavities.

'Historically, the lungs of grass-eating birds and dinosaurs have the same origin. 200 million years ago, there were a lot of 'utopian' combinations going on and that could be the factor that created the giant form of dinosaurs, ' Professor Sander said.
