Datos curiosos
Eogranivora is the only Early Cretaceous ornithuromorph bird that has direct evidence of eating seeds.1
It had no teeth at all, which is unusual for a bird from its time. Many other early birds still had small teeth.1
Eogranivora had no hallux, the backward-pointing toe that most birds use to perch. This suggests it lived on the ground.1
Its fossil was first thought to be a different bird called Hongshanornis, but scientists later realized it was a new species.2
The fossil preserves at least 15 seeds inside the crop area, each about 4.3 mm long.1
Eogranivora lived about 125 million years ago during the Early Cretaceous period.1

- Eogranivora was named in 2018 by Zheng Xiaoting and colleagues. The fossil was found at Dawangzhangzi in China and was originally mistaken for Hongshanornis.21
- Aínda en debate
- Scientists are not sure if Eogranivora ate only seeds or also other foods, because some modern birds that eat hard items also use gizzard stones.1
