Datos curiosos
All known fossils of Archaeorhynchus have more than three dozen gizzard stones in their stomach area.21
The first fossil was found in the Yixian Formation in Liaoning, China, and was reported in 2005.1
Archaeorhynchus had a long, flat beak that was not pointed, so it probably did not eat fish or insects.2
It had strong wings and an alula, which is a small feather that helps with flight control, similar to modern birds.2
The name Archaeorhynchus comes from Greek words meaning 'ancient snout'.1
