酷東西

趣味知識

Eotyrannus had D-shaped teeth in its upper jaw, just like T. rex.2

Its hands were long and slender, with fingers that could grab prey.2

The fossil was found in a plant debris bed, which was a swampy floodplain.2

Eotyrannus lived alongside other dinosaurs like Neovenator, Iguanodon, and Polacanthus.1

Scientists think Eotyrannus was a subadult when it died, because some of its bones were not fully fused.2

The name Eotyrannus means 'dawn tyrant' because it was an early relative of the tyrannosaurs.1

關於 Eotyrannus 最常被問的問題

?How big was Eotyrannus?

The only known specimen was about 4.5 metres long, but it was a subadult, so adults may have been larger.1 2

?When did Eotyrannus live?

Eotyrannus lived during the Early Cretaceous period, about 131 to 126 million years ago.3

?What did Eotyrannus eat?

Eotyrannus was a predator that probably ate small to medium-sized dinosaurs like Hypsilophodon and Iguanodon, as well as mammals and reptiles.3

?Where was Eotyrannus found?

Eotyrannus was found on the Isle of Wight in England, in a plant debris bed from the Wessex Formation.1 3

?How fast could Eotyrannus run?

Scientists think Eotyrannus was fast and agile because it had unusually long legs, but no exact speed is known.3

?Is Eotyrannus a dinosaur?

Yes, Eotyrannus is a dinosaur. It is a tyrannosauroid theropod, which is a type of meat-eating dinosaur.1
