趣味知識

Achillobator is named after the Greek hero Achilles, because of the large Achilles tendon that helped power its sickle claw.1

It was one of the largest dromaeosaurs, along with Utahraptor and Austroraptor, reaching about 5 metres (16 feet) long.1

Unlike many other raptors, Achillobator had a very robust, heavily built skeleton and short, stocky legs.1

Its legs were not built for high-speed running; instead, it was a powerful ambush predator that could leap onto prey.1

The first fossils were found in 1989 by a Mongolian-Russian expedition, but the dinosaur was not named until 1999.1

Achillobator lived in a warm, wet environment with rivers and lakes, about 96 to 89 million years ago.1

Scientists think Achillobator may have used its feathered arms to help balance while wrestling with prey.1

關於 Achillobator 最常被問的問題

?How big was Achillobator?

About 4.5 to 5 metres (15 to 16 feet) long and weighed 250 to 300 kilograms (550 to 660 pounds). That is as long as a car and as heavy as a polar bear.1 2

?Did Achillobator have feathers?

Yes, scientists are confident it had feathers. Although no feathers were found with its fossils, its close relatives had feathers, so Achillobator almost certainly did too.1

?What did Achillobator eat?

It was a carnivore that hunted large prey. It used its giant sickle claw on each foot to help it catch and hold onto animals.1

?How fast could Achillobator run?

Not very fast. Its short, stocky legs were built for power, not speed. It was an ambush predator that leaped onto prey rather than chasing it.1

?When did Achillobator live?

It lived during the Late Cretaceous period, about 96 to 89 million years ago.1 2

?Where was Achillobator found?

Its fossils were discovered in the Bayan Shireh Formation of Mongolia, in the Gobi Desert.1

?Why is it called Achillobator?

Its name means 'Achilles hero' in Latin and Mongolian. It is named after the Greek hero Achilles because of the large Achilles tendon that helped power its sickle claw.1

?Was Achillobator bigger than Velociraptor?

Yes, much bigger. Achillobator was about 5 metres long, while Velociraptor was only about 2 metres long. Achillobator was one of the largest dromaeosaurs.1

迷思破解王

迷思： Some people think all raptors were fast runners.

真相： Achillobator had short, stocky legs and was not built for speed. It was a powerful ambush predator that used strength and leaping to catch prey.1
