酷東西

趣味知識

Kank lived about 70 million years ago in a warm, wet place with rivers and ponds.1

Its neck bones had air chambers inside, making them light and strong.1

Kank had a big claw on its second toe, like other raptors, but it probably used it for fishing, not hunting on land.1

The first Kank fossils were found in 2018, but scientists needed more bones to know it was a new species.1

Kank shared its home with giant predators like Maip macrothorax, a megaraptorid over 10 metres long.1

Kank is part of a group called unenlagiids, which are found in South America, Antarctica, Australia and Madagascar.1

關於 Kank 最常被問的問題

?How big was Kank?

About 2.5 to 3 metres long. It weighed roughly 27 kilograms.1 2

?What did Kank eat?

Kank mostly ate fish, like a modern heron. It may have also eaten frogs, lizards, turtles and small mammals that lived in its wetland home.1 2

?Did Kank have feathers?

Scientists think Kank probably had feathers, because it belongs to a group of dinosaurs called unenlagiids that are closely related to birds. No direct feather fossils of Kank have been found yet.2

?When did Kank live?

Kank lived about 70 million years ago, during the Late Cretaceous period. That was near the very end of the age of dinosaurs.1 2

?Where was Kank found?

Kank was discovered at La Anita farm near El Calafate in Santa Cruz, Argentina. The fossils come from the Chorrillo Formation in southern Patagonia.1 2

?Was Kank bigger than Velociraptor?

Yes, Kank was a bit bigger. Velociraptor was about 2 metres long, while Kank grew up to 3 metres long.1

迷思破解王

迷思： All raptor-like dinosaurs were fast land hunters like Velociraptor.

真相： Kank was a fish-eater that behaved like a heron, not a speedy land predator.1
