酷東西

趣味知識

Euhelopus had longer front legs than back legs, like a giraffe.1

Its neck was about 4 metres long and made of 17 vertebrae.1

The first fossils were found by a priest in 1913, but the dinosaur was named in 1929.1

Euhelopus was originally called Helopus, but that name was already used for a bird, so it was changed.1

Scientists think Euhelopus is closely related to titanosaurs, a group of huge sauropods.1

Its bones had many tiny air pockets, making them lighter.1

關於 Euhelopus 最常被問的問題

?How big was Euhelopus?

Scientists disagree on its size. Some earlier estimates said it was about 15 metres (49 feet) long and weighed 15 to 20 tonnes (17 to 22 short tons). Newer estimates suggest it was about 11 metres (36 feet) long and weighed around 3.5 to 5.9 tonnes (3.9 to 6.5 short tons).1

?What did Euhelopus eat?

Euhelopus was a herbivore, meaning it ate plants. Its strong, broad teeth and skull shape suggest it fed on tough, hardy vegetation.1 5

?When did Euhelopus live?

Euhelopus lived during the Early Cretaceous period, between about 143 and 133 million years ago.1

?Where was Euhelopus found?

Euhelopus fossils were found in Shandong Province, China. It was one of the first dinosaurs ever discovered in China.1 2
