Potamornis

Igama lithetha: “river bird”3
Yayitya: InyamaIintaka zokuqalaiCretaceous yamva

Potamornis was a small, toothed bird that lived near the end of the Age of Dinosaurs. It hunted along the shores of a river in what is now Wyoming, USA. It was a fast, meat-eating bird that could probably run and maybe fly a little.3

izinto ezimnandi

Iinyani ezimnandi

1

Potamornis is known from just one partial skull bone, called a quadrate, which was found in Wyoming.3

2

It lived about 72 to 66 million years ago, right before the big extinction that killed the non-bird dinosaurs.1

3

Potamornis belonged to a group of ancient birds called Hesperornithiformes, which were mostly diving birds with teeth.3

4

The name Potamornis means 'river bird', because it was found in rocks that were once a riverbed.3

5

Scientists think Potamornis was a ground-dwelling bird that could run fast on land.3

6

It laid eggs, like all birds do, and probably built nests on the ground.1

Umfanekiso owenziwe yi-AI obonisa indlela Potamornis 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: Potamornis

?How big was Potamornis?

It was a small bird, weighing perhaps 1.5 or 2 kilograms (3.3 to 4.4 pounds).2

?Did Potamornis have teeth?

Yes, it was a toothed bird. It belonged to a group of ancient birds called Hesperornithiformes, which had teeth.2

?Could Potamornis fly?

Probably not. It was a flightless diving bird, like other members of its group, though some scientists think it might have been able to fly a little.2

?What did Potamornis eat?

It was a meat-eater (carnivore). It likely hunted for fish and other small animals in the water.3

Inyaniso ngeentsomi

Intsomi: Some people think Potamornis was a dinosaur like T. rex.

Inyaniso: Potamornis was a bird, and while birds are dinosaurs, it was a small, feathered, flying or running bird, not a big predator.3

Ukufunyanwa
Potamornis was named by Elzanowski, Paul, and Stidham in 2001, based on a skull bone found in the Lance Formation of Wyoming.3
Kusaxoxwa ngayo
Scientists are still not sure exactly how Potamornis is related to other ancient birds, because only a single skull bone has been found.3
