gauza bikainak

Datu dibertigarriak

Asilisaurus is one of the oldest known bird-line archosaurs, meaning it is more closely related to dinosaurs and birds than to crocodiles.2

Its name comes from the Swahili word 'asili' meaning ancestor or foundation, and the Greek word 'sauros' meaning lizard.1

Fossils of at least 14 individuals were found together in a bonebed in Tanzania.1

Asilisaurus had a beak at the tip of its snout, similar to some plant-eating dinosaurs that came later.1

Scientists think Asilisaurus walked on all four legs because its front and back legs were similar in length.1

The teeth of Asilisaurus were peg-like and had tiny serrations, which helped it chew plants.1

Asilisaurus: gehien egindako galderak

?How big was Asilisaurus?

Asilisaurus was a silesaurid, not a dinosaur. It was about 1 to 3 metres (3 to 10 ft) long and 0.5 to 1 metre (2 to 3 ft) tall at the hip. It weighed roughly 10 to 30 kilograms (20 to 70 lb).1

?Was Asilisaurus a dinosaur?

Asilisaurus was not a dinosaur, but a close relative. It belonged to a group called silesaurids, which are the sister group to dinosaurs.2

?What did Asilisaurus eat?

Asilisaurus probably ate plants or a mix of plants and small animals. Its beak and peg-like teeth suggest it was an omnivore or herbivore.1 3

?When did Asilisaurus live?

Asilisaurus lived about 247 to 241 million years ago, during the Middle Triassic period. It is one of the oldest known bird-line archosaurs.1 3

?Where was Asilisaurus found?

Asilisaurus fossils were found in Tanzania, in a rock formation called the Manda Beds. At least 14 individuals were discovered in a single bonebed.1

?Did Asilisaurus walk on two legs or four?

Asilisaurus probably walked on all four legs. Its front and back legs were similar in length, which suggests a quadrupedal stance.1 2
