酷東西

趣味知識

Afrovenator is the most complete predatory dinosaur from the Cretaceous period ever found in Africa.2

Its skeleton was discovered in 1993 by a team led by famous paleontologist Paul Sereno.1 2

Afrovenator had a flexible, S-shaped neck and strong neck muscles, which helped it move its head side to side and up and down while hunting.1

Its lower leg bones were long compared to its thigh bone, meaning it was probably a fast runner.1

The name Afrovenator comes from Latin words meaning 'African hunter'.1

Afrovenator lived during the Middle to Late Jurassic Period, about 167 to 157 million years ago.1

?How big was Afrovenator?

Afrovenator was about 8 metres (26 feet) long from snout to tail tip, stood about 1.9 metres (6.2 feet) tall at the hips, and weighed around 790 kg (1,740 lb). Different scientists give slightly different estimates, but it was a medium-sized, slender predator.1

Afrovenator was a meat-eater. It had long, blade-shaped teeth for slicing into prey, and it probably hunted other dinosaurs and animals in what is now the Sahara Desert.1 2

?When did Afrovenator live?

Afrovenator lived during the Middle to Late Jurassic Period, about 167 to 157 million years ago. Some older sources said it lived in the Early Cretaceous, but scientists now think it is Jurassic in age.1

?Where was Afrovenator found?

Afrovenator was discovered in 1993 in the Tiourarén Formation of Niger, in West Africa. Its skeleton is the most complete predatory dinosaur from the Jurassic period ever found in Africa.1 2

?Was Afrovenator a fast runner?

Yes, Afrovenator was probably a fast runner. It had long lower leg bones compared to its thigh bone, and its bones were slender and light, which helped it run quickly after prey.1 2

?Is Afrovenator related to Allosaurus?

Afrovenator was a cousin to Allosaurus, but not a close relative. It belonged to a group called megalosaurids, while Allosaurus was in a different family. Afrovenator had longer, more slender bones and was lighter and faster than Allosaurus.1 2

發現: Afrovenator was named in 1994 by Paul Sereno and his team, based on a nearly complete skeleton found in Niger, West Africa. The species name, abakensis, comes from the Tuareg name for the region where it was found.1
仍有爭議: Scientists are not sure exactly how big Afrovenator was, because different estimates give different lengths and weights.1
