Utuntu dushimishije

1

Parahesperornis could not fly. Its wings were tiny and useless for flying, but its legs were strong for swimming.12

2

It had sharp teeth in its beak, which is unusual for modern birds. These teeth helped it grab slippery fish.12

3

Parahesperornis is known from two nearly complete skeletons, which is rare for ancient birds. Most are found as just a few bones.2

4

It lived in the Western Interior Seaway, a shallow sea that covered central North America during the Cretaceous.1

5

The first fossil of Parahesperornis was found in 1894, but it was not named until 1984 by scientist L. D. Martin.24

6

Parahesperornis was about the size of a modern loon or a small penguin, around 60 to 90 centimeters long.2
