名字的意思： “dawn shark”1

吃：肉肉食恐龍白堊紀早期

Eocarcharia was a fierce meat-eating dinosaur that lived about 110 million years ago. It had blade-shaped teeth and a thick bony eyebrow above its eyes, which made it look very scary. This predator was one of the early giant hunters of its time.2 1

酷東西

趣味知識

Eocarcharia belongs to a group called carcharodontosaurids, which means 'shark-toothed lizards' because of their sharp, serrated teeth.1

Its name comes from Greek words meaning 'dawn shark', because it was an early member of the shark-toothed dinosaur family.1

The dinosaur had a thick, bumpy bony ridge above its eyes, which scientists call a 'brow boss'. This might have been used for display or fighting.1

Eocarcharia lived alongside other dinosaurs like the spinosaurid Suchomimus and the abelisaurid Kryptops in what is now the Sahara Desert.1

Its fossils were found in the Elrhaz Formation of Niger, which was once a river environment with many different animals.1

Scientists think Eocarcharia was about 7.6 metres (25 feet) long and stood about 1.8 metres (6 feet) tall at the hips.2

Eocarcharia is one of the oldest known carcharodontosaurids, along with relatives like Acrocanthosaurus from North America.1

關於 Eocarcharia 最常被問的問題

?How big was Eocarcharia?

About 6 to 8 metres (20 to 26 feet) long. That is about half the size of its bigger relatives like Giganotosaurus.4 2

?What did Eocarcharia eat?

It ate meat. Its blade shaped teeth were designed for hunting prey.2

?Why did Eocarcharia have a bony eyebrow?

The thick, bumpy bony ridge above its eyes might have been used for display or head-butting with other Eocarcharia. It may have been covered in keratin.4

?Is Eocarcharia a dinosaur?

Yes, it is a theropod dinosaur, a meat-eating dinosaur that walked on two legs.4

?When did Eocarcharia live?

It lived about 110 million years ago, during the Early Cretaceous period.2

?Where was Eocarcharia found?

Its fossils were found in the Elrhaz Formation of Niger, in the Sahara Desert. That area was once a river environment.4
