Igama lithetha: “near Hesperornis”1
Yayitya: InyamaIintaka zokuqalaiCretaceous yamva

Parahesperornis was a flightless bird that lived in the sea. It swam like a penguin and had teeth in its beak. It lived during the time of dinosaurs, about 85 to 82 million years ago.14

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI obonisa indlela Parahesperornis esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.
ubuzile

Eyona mibuzo ibuzwa kakhulu: Parahesperornis

?Was Parahesperornis a dinosaur?

Yes, it was a type of prehistoric bird. While birds are descendants of dinosaurs, scientists classify Parahesperornis as an avialan bird rather than a dinosaur.1

?How big was Parahesperornis?

It was about 60 to 90 centimetres (2 to 3 feet) long, roughly the size of a modern loon or a small penguin.1

?Did Parahesperornis have teeth?

Yes, it had sharp teeth in its beak, which helped it grab slippery fish.2

?Could Parahesperornis swim?

Yes, it was a foot-propelled diving bird that swam like a penguin, using its strong legs to chase fish underwater.3

Inyaniso ngeentsomi

Intsomi: Some people think Parahesperornis was a dinosaur.

Inyaniso: Parahesperornis was a bird, not a dinosaur. Birds evolved from dinosaurs, but Parahesperornis is classified as an avialan, which is a group that includes modern birds and their extinct relatives.14
