酷東西

趣味知識

Eucnemesaurus was once mistaken for a giant meat-eater called Aliwalia, but scientists later realized it was a plant-eating sauropodomorph.1

The name Eucnemesaurus means 'good tibia lizard' because its shin bones (tibiae) were very strong and sturdy.1

Fossils of Eucnemesaurus are about 228 million years old, from the Late Triassic period.1

A second species, Eucnemesaurus entaxonis, was named in 2015 based on a nearly complete skeleton.2

Eucnemesaurus is closely related to Riojasaurus, another early long-necked dinosaur from South America.1 3

?What did Eucnemesaurus eat?

Eucnemesaurus was a plant-eater. It is a sauropodomorph, a group of long-necked dinosaurs that ate plants.1

?Was Eucnemesaurus a dinosaur?

Yes, Eucnemesaurus was a dinosaur. It was a basal sauropodomorph, which is a type of long-necked dinosaur.1

?When did Eucnemesaurus live?

Eucnemesaurus lived during the Late Triassic period, about 228 million years ago.1

迷思破解王

迷思： Eucnemesaurus was a giant carnivorous dinosaur like T. rex.

真相： Eucnemesaurus was actually a plant-eater. The confusion came from a meat-eating jawbone that was mixed with its fossils.1
