Did ancient birds lose teeth for flight ?

New research has suggested that ancient birds may have lost their teeth to lose enough weight to help them fly. The 150 million-year-old Archaeopteryx did have teeth but within 20 milion years some birds had none.
In a new research, scientists have suggested that ancient birds lost their teeth in order to shed some weight to get airborne. Archaeopteryx, at 150 million years old still the oldest known bird, had an imposing set of teeth. But within 20 million years, at least some birds were toothless.
