Datos curiosos
Janavis lived about 66.8 million years ago, just 800,000 years before the asteroid that killed the dinosaurs.1
Its wing bones were hollow and filled with air, like modern birds, making it lighter for flying.1
The fossil was found in a Belgian quarry in 2000 by an amateur fossil hunter named Rudi Dortangs.1
Janavis had a skull that could move its upper jaw up and down, a feature of modern birds called neognathous palate.1
Scientists first thought a piece of its skull was a wing bone, until a CT scan in 2021 showed the truth.1
Janavis was bigger than its relative Ichthyornis, with a wingspan of about 1.5 metres (5 feet).1

- Aínda en debate
- Scientists debate whether Janavis could fly as well as modern birds, because its wing bones were very air-filled but its shoulder blade lacked a normal hook.1
