ເລື່ອງໜ້າຮູ້ມ່ວນໆ

Hesperornis was one of the first birds to give up flying and become a full-time swimmer.2

Its legs were placed far back on its body, like a loon, making it clumsy on land but a powerful diver.1

Hesperornis had teeth in its beak, which is rare for birds. It used them to catch fish.1 2

The first fossils of Hesperornis were found by famous fossil hunter Othniel Charles Marsh in 1870 in Kansas.1 2

Several species of Hesperornis lived from about 90 to 66 million years ago, during the Late Cretaceous.5

Hesperornis fossils have been found in many places, including Canada, the United States, Russia, and Sweden.5

ຄຳຖາມທີ່ຖືກຖາມຫຼາຍທີ່ສຸດກ່ຽວກັບ Hesperornis

?How big was Hesperornis?

About 1.5 to 2 metres (4.9 to 6.6 ft) long and weighed around 10.6 kilograms (23 lb).1

?Did Hesperornis have teeth?

Yes, it had teeth in its beak, which is rare for birds. The teeth sat in a groove, not in individual sockets.1

?Could Hesperornis fly?

No, it could not fly. Its wings were tiny and useless for flight, and its breastbone lacked a keel for flight muscles.1 3

?What did Hesperornis eat?

It ate fish, which it caught with its tooth-lined beak while diving in the sea.4

?When did Hesperornis live?

It lived during the Late Cretaceous period, about 83.6 to 72 million years ago, and possibly into the early Maastrichtian.1

?Where was Hesperornis found?

Fossils have been found in Kansas, Canada, Russia, Sweden, and other places, mostly in marine rocks.1

?Could Hesperornis walk on land?

It was clumsy on land. Its legs were placed far back, so it probably pushed itself along on its belly like a seal.1

ໄຂຄວາມເຊື່ອຜິດ

ຄວາມເຊື່ອຜິດ: Some people think Hesperornis was a dinosaur.

ຄວາມຈິງ: Hesperornis was a bird, not a dinosaur. Birds evolved from dinosaurs, but Hesperornis itself is classified as a bird.1
