Scientists from China, Switzerland, and Germany have collaborated to study an ancient beak bird specimen from the Jehol Biota in the western Liaoning region of China about 120 million years ago, revealing an important stage in the evolution of birds.
The ancient beak bird was only the size of a pigeon, and because it did not develop teeth, it represented important evidence of the differentiation between modern toothless birds and anti-birds with teeth.
The picture shows the restoration of the ancient beak bird provided by the research team.
