Utuntu dushimishije

1

Gracilornis had a very small sternum, or breastbone, compared to its body length. The sternum was only about 11% of the trunk length.3

2

This bird lived around 110 million years ago, during the Early Cretaceous period.1

3

The name Gracilornis comes from Latin and Greek words meaning 'slender bird', because its skeleton was very thin and light.1

4

Gracilornis is known from a nearly complete skull and skeleton, which helps scientists understand what it looked like.1

5

It belonged to a group called Enantiornithes, which were the most common birds during the Cretaceous period.1
